Description

[Technical Field]

[0001] The present invention relates to a sailing device and a watercraft. [Background technology]

[0002] BACKGROUND ART Conventionally, there is known a ship that includes a base member to which the lower end side of a mast is connected and that is rotatable within a plane perpendicular to the up-and-down direction of the hull (see, for example, Patent Document 1).

[0003] Patent Document 1 describes a sailing ship (marine) equipped with a sail, a mast that extends along the vertical direction of the hull and supports the sail, a boom that extends along a plane perpendicular to the vertical direction of the hull and supports the sail from the lower side of the hull in the vertical direction, and a circular guide (base member) to which the lower end of the mast is connected and that is rotatable in a plane perpendicular to the vertical direction of the hull. In other words, the sailing ship described in Patent Document 1 is configured so that the circular guide allows the sail, mast, and boom to rotate together in a plane perpendicular to the vertical direction of the hull. In the sailing ship described in Patent Document 1, the base of the boom is connected to the lower end of the mast. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2-68290 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the sailing ship (marine) described in Patent Document 1, the base of the boom is connected to the lower end of the mast, so the mast is subjected to a load for supporting the boom. In this case, the mast is required to have a relatively high level of strength. Therefore, a configuration is desired that allows the sail, mast, and boom to rotate integrally in a plane perpendicular to the up-and-down direction of the hull while suppressing the increase in the strength required of the mast.

[0006] This invention has been made to solve the above-mentioned problems, and one object of this invention is to provide a sailing device and a ship that can rotate the sail, mast, and boom together in a plane perpendicular to the up-and-down direction of the hull while suppressing the increase in the strength required of the mast. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, a sailing device according to a first aspect of the present invention is a sailing device attached to a hull, and comprises a sail, a mast that extends along the vertical direction of the hull and supports the sail, a boom that extends along a plane perpendicular to the vertical direction of the hull and supports the sail from the lower side of the hull in the vertical direction, and a base member to which the lower end side of the mast and the base side of the boom are connected and which is rotatable within a plane perpendicular to the vertical direction of the hull.

[0008] As described above, the sailing device according to the first aspect of the present invention includes a base member to which the lower end of the mast and the base of the boom are connected, and which is rotatable in a plane perpendicular to the vertical direction of the hull. This allows the sail, mast, and boom to rotate together in a plane perpendicular to the vertical direction of the hull using the base member. Furthermore, because the base of the boom is connected to the base member, the mast is not subjected to a load to support the boom. This reduces the strength required of the mast compared to when the base of the boom is connected to the lower end of the mast. As a result, the sail, mast, and boom can be rotated together in a plane perpendicular to the vertical direction of the hull while minimizing the increase in the strength required of the mast.

[0009] The sailing device according to the first aspect preferably further comprises an arc-shaped or circular base guide member that supports and guides the base member when it rotates in a plane perpendicular to the vertical direction of the hull. With this configuration, the arc-shaped or circular base guide member that supports and guides the base member makes it easy to rotate the base member in a plane perpendicular to the vertical direction of the hull.

[0010] In the above-described configuration of the sailing device including base guide members, preferably, a pair of base guide members are provided, with one and the other of the pair of base guide members being arranged in an arc shape to the left and right of the center of the mast in the transverse direction of the hull. This configuration allows the installation space for the base guide members to be reduced compared to when the base guide members are circular. Furthermore, since the pair of base guide members are unlikely to be arranged forward and aft of the center of the mast in the transverse direction of the hull, the base guide members are less likely to interfere with the movement of passengers in the transverse direction of the hull.

[0011] In the above-mentioned sailing device having a base guide member, the base guide member preferably supports and guides the base member via a base moving member that is movable along the arc-shaped or circular base guide member. With this configuration, the base member can be easily guided and supported by the arc-shaped or circular base guide member by the base moving member that is movable along the arc-shaped or circular base guide member.

[0012] In the above-described configuration in which the base guide member supports and guides the base member via a base moving member that is movable along the arc-shaped or circular base guide member, the base guide member is preferably a rail formed in an arc-shaped or circular shape, and the base moving member is a roller member that is movable along the arc-shaped or circular rail. With this configuration, it is possible to easily realize a configuration in which the base guide member supports and guides the base member via the base moving member that is movable along the arc-shaped or circular base guide member.

[0013] The sailing device according to the first aspect preferably further includes an arc-shaped boom guide member that is positioned forward or aft of the base member in the fore-and-aft direction of the hull, connected to the tip of the boom, and that guides and supports the boom when the base member rotates in a plane perpendicular to the up-and-down direction of the hull. With this configuration, the arc-shaped boom guide member, connected to the tip of the boom and that guides and supports the boom, allows the base member to easily rotate in a plane perpendicular to the up-and-down direction of the hull. Furthermore, because the boom guide member is positioned forward or aft of the base member in the fore-and-aft direction of the hull and connected to the tip of the boom, the boom guide member is unlikely to be positioned in the center of the fore-and-aft direction of the hull. This prevents the boom guide member from interfering with the movement of passengers in the fore-and-aft direction of the hull.

[0014] In the above-described configuration of the sailing device equipped with a boom guide member, preferably, the sail includes a rear sail positioned aft in the fore-and-aft direction of the hull, the boom includes a rear boom supporting the rear sail, and the boom guide member is connected to the tip of the rear boom and positioned aft in the fore-and-aft direction of the hull relative to the base member. With this configuration, the boom guide member is positioned aft in the fore-and-aft direction of the hull relative to the base member, making it easier to position the boom guide member aft in the fore-and-aft direction of the hull. This prevents the boom guide member from obstructing the passenger's forward field of view in the fore-and-aft direction of the hull.

[0015] In the above-described configuration of the sailing device equipped with a boom guide member, the boom guide member preferably supports and guides the boom via a boom moving member that is movable along the arc-shaped boom guide member. With this configuration, the boom can be easily guided and supported by the arc-shaped boom guide member by the boom moving member that is movable along the arc-shaped boom guide member.

[0016] In the above-described configuration in which the boom guide member supports and guides the boom via a boom moving member that is movable along the arc-shaped boom guide member, the boom guide member is preferably a rail formed in an arc shape, and the boom moving member is a bearing member that is movable along the arc-shaped rail. With this configuration, it is possible to easily realize a configuration in which the boom guide member supports and guides the boom via a boom moving member that is movable along the arc-shaped boom guide member.

[0017] In the sailing device according to the first aspect, the mast preferably has an inverted V shape in which the two mast sections gradually approach each other toward the upper end of the mast. This configuration eliminates the need for a separate wire to support the two mast sections in the direction in which they are aligned, simplifying the device configuration and eliminating the need to adjust the wire.

[0018] In the sailing device according to the first aspect, the boom preferably has an inverted V shape in which the two boom sections gradually approach each other toward the tip of the boom. This configuration eliminates the need for a separate wire to support the two boom sections in the direction in which they are aligned, simplifying the device configuration and eliminating the need to adjust the wire.

[0019] In the sailing device according to the first aspect, preferably, the sail includes a front sail disposed on the front side of the hull in the longitudinal direction and an aft sail disposed on the aft side of the hull in the longitudinal direction, and the boom includes a front boom supporting the front sail and an aft boom supporting the aft sail, the aft end of the front boom being connected to the front end of the base member, and the front end of the aft boom being connected to the aft end of the base member. With this configuration, because the aft end of the front boom is connected to the front end of the base member, no load is applied to the mast to support the front boom. This reduces the strength required of the mast compared to when the aft end of the front boom is connected to the lower end of the mast. Also, because the front end of the aft boom is connected to the aft end of the base member, no load is applied to the mast to support the aft boom. This reduces the strength required of the mast compared to when the front end of the aft boom is connected to the lower end of the mast.

[0020] The sailing device according to the first aspect preferably further comprises an actuator for adjusting the rotation angle of the base member. With this configuration, the actuator can easily and automatically adjust the rotation angle of the base member.

[0021] In addition, in order to achieve the above-mentioned object, a watercraft according to a second aspect of the present invention comprises a hull and a sailing device attached to the hull, the sailing device comprising a sail, a mast extending along the vertical direction of the hull and supporting the sail, a boom extending along a plane perpendicular to the vertical direction of the hull and supporting the sail from the lower side of the hull in the vertical direction, and a base member to which the lower end side of the mast and the base side of the boom are connected and which is rotatable within a plane perpendicular to the vertical direction of the hull.

[0022] In a watercraft according to a second aspect of the present invention, as described above, the sailing device includes a base member to which the lower end of the mast and the base of the boom are connected and which is rotatable in a plane perpendicular to the vertical direction of the hull. This allows the sail, mast, and boom to rotate together in a plane perpendicular to the vertical direction of the hull, just as in the sailing device according to the first aspect. Furthermore, just as in the sailing device according to the first aspect, the strength required of the mast can be reduced compared to when the base of the boom is connected to the lower end of the mast. As a result, just like in the sailing device according to the first aspect, the sail, mast, and boom can be rotated together in a plane perpendicular to the vertical direction of the hull without increasing the strength required of the mast.

[0023] In the watercraft according to the second aspect, the sailing device preferably further comprises an arc-shaped or circular base guide member that supports and guides the base member when it rotates in a plane perpendicular to the vertical direction of the hull. With this configuration, as with the sailing device according to the first aspect, the arc-shaped or circular base guide member that supports and guides the base member makes it easy to rotate the base member in a plane perpendicular to the vertical direction of the hull.

[0024] In the sailing device for a watercraft according to the second aspect, a pair of base guide members are preferably provided, with one and the other of the pair of base guide members arranged in an arc shape on the left and right sides of the center of the mast in the transverse direction of the hull. This configuration, like the sailing device according to the first aspect, allows for a smaller installation space for the base guide members on the hull compared to when the base guide members are circular. Furthermore, like the sailing device according to the first aspect, the base guide members are less likely to interfere with the movement of passengers in the fore-and-aft direction of the hull.

[0025] In the sailing device for a boat according to the second aspect, the base guide member preferably supports and guides the base member via a base moving member that is movable along the arc-shaped or circular base guide member. With this configuration, as with the sailing device according to the first aspect, the base member can be easily guided and supported by the arc-shaped or circular base guide member using the base moving member that is movable along the arc-shaped or circular base guide member.

[0026] In the vessel according to the second aspect, the base guide member is configured to support and guide the base member via a base moving member that is movable along the arc-shaped or circular base guide member, and the base guide member is preferably a rail that is formed in an arc-shaped or circular shape, and the base moving member is a roller member that is movable along the arc-shaped or circular rail. This configuration makes it easy to realize a configuration in which the base guide member supports and guides the base member via a base moving member that is movable along the arc-shaped or circular base guide member, as in the sailing device according to the first aspect.

[0027] In the watercraft according to the second aspect, the sailing device preferably further comprises an arc-shaped boom guide member disposed forward or aft of the base member in the fore-and-aft direction of the hull, connected to the tip of the boom, and guiding and supporting the boom as the base member rotates in a plane perpendicular to the up-and-down direction of the hull. With this configuration, as with the sailing device according to the first aspect, the arc-shaped boom guide member connected to the tip of the boom and guiding and supporting the boom allows the base member to easily rotate in a plane perpendicular to the up-and-down direction of the hull. Furthermore, as with the sailing device according to the first aspect, the boom guide member is prevented from interfering with the movement of passengers in the fore-and-aft direction of the hull.

[0028] In the configuration of the sailing device for a watercraft according to the second aspect, which is equipped with a boom guide member, preferably the sail includes a rear sail arranged aft in the fore-and-aft direction of the hull, the boom includes a rear boom supporting the rear sail, and the boom guide member is connected to the tip of the rear boom and arranged aft in the fore-and-aft direction of the hull relative to the base member. With this configuration, as with the sailing device according to the first aspect, the boom guide member can be prevented from obstructing the passenger's forward field of view in the fore-and-aft direction of the hull. [Effects of the Invention]

[0029] According to the present invention, as described above, it is possible to provide a sailing device and a ship that can rotate the sail, mast, and boom together in a plane perpendicular to the vertical direction of the hull while suppressing the increase in the strength required of the mast.

[0033] (Vessel configuration) As shown in FIG. 1 , the boat 110 includes a hull 111, two outboard motors 112, and a sailing device 100. The hull 111 has two body sections 111a aligned in the fore-and-aft direction of the hull 111 and connected by a deck 111b. In other words, the boat 110 is a catamaran. The deck 111b is provided with an operating unit for steering the boat 110, seats for passengers, etc. The two outboard motors 112 are attached to the stern of the hull 111. Specifically, each of the two outboard motors 112 is attached to the rear end of each of the two body sections 111a. Each of the two outboard motors 112 is an engine-driven outboard motor configured to drive a propeller with an engine. The sailing device 100 is attached to the top of the hull 111. The sailing device 100 is used for sailing the boat 110.

[0034] (Configuration of sailing devices) As shown in Figure 1, the sailing device 100 comprises a sail 10, a mast 20, a boom 30, a base member 40, an actuator 50, a base guide member 60, a base guide support member 70, a boom guide member 80, and a boom guide support member 90. In Figure 1, the sail 10 is indicated by a two-dot chain line.

[0035] <Sail> As shown in FIG. 1, the sail 10 is configured so that its opening degree can be adjusted to catch wind to generate propulsive force for the vessel 110. The sail 10 is configured so that it opens in the fore-and-aft direction and the up-and-down direction of the hull 111 when the boom 30 extends in the fore-and-aft direction of the hull 111. In other words, the sail 10 is a fore-and-aft sail. The sail 10 has a triangular shape. The sail 10 includes a front sail 11 arranged on the front side of the hull 111 and an aft sail 12 arranged on the rear side in the fore-and-aft direction of the hull 111.

[0036] <Mast> As shown in FIG. 1, the mast 20 extends from the base member 40 toward the upper side of the hull 111 in the vertical direction of the hull 111. The mast 20 supports the sail 10. The mast 20 has an inverted V shape in which two mast sections 20a gradually approach each other toward the upper end 20b of the mast 20. The mast 20 includes a mast section connection part 20c that connects the two mast sections 20a together. Note that FIG. 1 shows an example in which the mast 20 includes two mast section connection parts 20c.

[0037] <boom> As shown in FIG. 1 , the boom 30 extends from the base member 40 along a plane perpendicular to the up-and-down direction of the hull 111. The boom 30 supports the sail 10 from the lower side of the hull 111 in the up-and-down direction. The boom 30 has an inverted V shape with two boom sections 30a gradually approaching each other toward the tip 30b of the boom 30. The boom 30 includes a front boom 31 that supports the front sail 11 and a rear boom 32 that supports the rear sail 12. When the front boom 31 extends along the fore-and-aft direction of the hull 111, the front boom 31 extends from the base member 40 toward the front side in the fore-and-aft direction of the hull 111. When the rear boom 32 extends along the fore-and-aft direction of the hull 111, the rear boom 32 extends from the base member 40 toward the rear side in the fore-and-aft direction of the hull 111.

[0038] <Base material> As shown in FIG. 1 , the base member 40 is formed in a plate shape extending along a plane perpendicular to the up-down direction of the hull 111. The lower end 20d of the mast 20 and the base portion 30c of the boom 30 are connected to the base member 40. Specifically, the lower end 20d of one of the two mast sections 20a and the lower end 20d of the other of the two mast sections 20a are connected to the left and right ends of the base member 40, respectively. The rear end 31a of each of the two boom sections 30a of the front boom 31 is connected to the front end 40a of the base member 40. The front end 32a of each of the two boom sections 30a of the rear boom 32 is connected to the rear end 40b of the base member 40.

[0039] The base member 40 is configured to be rotatable about a rotation center axis C in a plane perpendicular to the up-down direction of the hull 111. That is, the base member 40 allows the mast 20 connected to the base member 40, the boom 30 connected to the base member 40, and the sail 10 supported by the mast 20 and the boom 30 to rotate integrally about the rotation center axis C in a plane perpendicular to the up-down direction of the hull 111. The rotation center axis C passes through the center of the base member 40 in the left-right direction of the hull 111 and through the front part of the base member 40 in the fore-and-aft direction of the hull 111.

[0040] <Actuator> 1, the actuator 50 adjusts the rotation angle of the base member 40. The actuator 50 is disposed between the base member 40 and the hull 111 in the up-down direction of the hull 111, and in the center of the hull 111 in the fore-and-aft direction. The actuator 50 is, for example, a hydraulic cylinder, an electric cylinder, or the like.

[0041] <Base guide member> As shown in FIG. 1, the base guide member 60 guides and supports the base member 40 when the base member 40 rotates in a plane perpendicular to the up-down direction of the hull 111. As shown in FIG. 2, the base guide member 60 is formed in an arc shape corresponding to a circle centered on the rotation central axis C. Specifically, the base guide member 60 is a rail formed in an arc shape corresponding to a circle centered on the rotation central axis C. As shown in FIG. 1, a pair of base guide members 60 are provided. One and the other of the pair of base guide members 60 are respectively arranged on the left and right sides of the center portion 20e of the mast 20 in the left-right direction of the hull 111, in an arc shape corresponding to a circle centered on the rotation central axis C. The base guide member 60 is arranged below the base member 40 in the up-down direction of the hull 111.

[0042] As shown in FIG. 2, the base guide member 60 supports and guides the base member 40 via a base moving member 61 that is movable along the arc-shaped base guide member 60, which corresponds to a circle centered on the rotation center axis C. The base moving member 61 is a roller member that is movable along an arc-shaped rail that corresponds to a circle centered on the rotation center axis C. Specifically, as shown in FIG. 3, the roller member (base moving member 61) is fixed to the base member 40 via a fastening member or the like so as to be rotatable in a direction from the roller member toward the rotation center axis C. Two roller members (base moving members 61) are provided so as to be aligned in the vertical direction of the hull 111 and to sandwich the rail (base guide member 60). The rail (base guide member 60) includes a plate-shaped rail main body 60a and protrusions 60b that protrude upward and downward from the plate-shaped rail main body 60a in the vertical direction of the hull 111. Each of the two roller members (base moving members 61) includes a recess that engages with the protrusion 60b of the rail (base guide member 60). As shown in Figure 4, the sailing device 100 is provided with two base moving members 61.

[0043] <Base guide support member> As shown in Figure 1, the base guide support member 70 supports the base guide member 60 from the lower side in the vertical direction of the hull 111. The base guide support member 70 is attached to the hull 111. The base guide support member 70 is configured by combining multiple rod-shaped members, multiple plate-shaped members, etc. so that the base guide support member 70 is at a predetermined position relative to the hull 111 in the vertical direction of the hull 111.

[0044] <Boom guide components> As shown in FIG. 1 , the boom guide member 80 supports and guides the boom 30 when the base member 40 rotates in a plane perpendicular to the up-down direction of the hull 111. The boom guide member 80 is formed in an arc shape corresponding to a circle centered on the rotation central axis C. Specifically, the boom guide member 80 is a rail formed in an arc shape corresponding to a circle centered on the rotation central axis C. The boom guide member 80 is disposed rearward of the base member 40 in the fore-and-aft direction of the hull 111, and is connected to the tip 30b of the boom 30. Specifically, the boom guide member 80 is connected to the tip 32b of the rear boom 32. The boom guide member 80 is disposed below the boom 30 in the up-down direction of the hull 111.

[0045] As shown in FIGS. 4 and 5, the boom guide member 80 supports and guides the boom 30 via a boom moving member 81 that is movable along the arc-shaped boom guide member 80, which corresponds to a circle centered on the rotation central axis C (see FIG. 1). The boom moving member 81 is a bearing member that is movable along an arc-shaped rail that corresponds to a circle centered on the rotation central axis C. Specifically, the bearing member (boom moving member 81) is fixed to the tip end 32b of the rear boom 32 via an aluminum plate 82, a connecting member 83, fastening members, etc. that extend in the vertical direction of the hull 111, so as to be rotatable in a direction from the bearing member toward the rotation central axis C. The aluminum plate 82 is fixed to the tip end 32b of the rear boom 32 with fastening members, etc. The upper end of the connecting member 83 is fixed to the lower end of the aluminum plate 82. The bearing member (boom moving member 81) is connected to the lower end of the connecting member 83 by a pivot shaft 84 so as to be rotatable about a pivot axis along the movement direction of the bearing member. As shown in FIGS. 5 and 6, the bearing member (boom moving member 81) includes a recess that is recessed upward in the up-down direction of the hull 111. The recess of the bearing member (boom moving member 81) is formed on the lower side of the bearing member (boom moving member 81) in the up-down direction of the hull 111. The rail (boom guide member 80) engages with the recess of the bearing member (boom moving member 81). As shown in FIGS. 4 and 5, the bearing member (boom moving member 81) includes a ball to reduce friction between the bearing member (boom moving member 81) and the rail (boom guide member 80).

[0046] <Boom guide support member> As shown in Figures 4 and 5, the boom guide support member 90 supports the boom guide member 80 from below in the vertical direction of the hull 111. As shown in Figure 1, the boom guide support member 90 is attached to the hull 111. The boom guide support member 90 is configured by combining multiple rod-shaped members so that the boom guide support member 90 is at a predetermined position relative to the hull 111 in the vertical direction of the hull 111.

[0047] (Effects of this embodiment) In this embodiment, the following effects can be obtained.

[0048] In this embodiment, as described above, the sailing device 100 includes a base member 40 to which the lower end 20d of the mast 20 and the base 30c of the boom 30 are connected, and which is rotatable in a plane perpendicular to the up-down direction of the hull 111. This allows the sail 10, mast 20, and boom 30 to rotate together in a plane perpendicular to the up-down direction of the hull 111. Furthermore, because the base 30c of the boom 30 is connected to the base member 40, no load is applied to the mast 20 to support the boom 30. This reduces the strength required of the mast 20 compared to when the base 30c of the boom 30 is connected to the lower end 20d of the mast 20. As a result, the sail 10, mast 20, and boom 30 can rotate together in a plane perpendicular to the up-down direction of the hull 111, while minimizing the increase in the strength required of the mast 20.

[0049] Furthermore, in this embodiment, as described above, the sailing device 100 is equipped with an arc-shaped base guide member 60 that supports and guides the base member 40 when the base member 40 rotates in a plane perpendicular to the up-down direction of the hull 111. As a result, the arc-shaped base guide member 60 that supports and guides the base member 40 makes it easy to rotate the base member 40 in a plane perpendicular to the up-down direction of the hull 111.

[0050] In this embodiment, as described above, a pair of base guide members 60 are provided. One and the other of the pair of base guide members 60 are respectively arranged in an arc shape on the left and right sides of the center 20e of the mast 20 in the left-right direction of the hull 111. This makes it possible to reduce the installation space for the base guide members 60 in the hull 111 compared to when the base guide members 60 are circular. Furthermore, because the pair of base guide members 60 are unlikely to be arranged forward and rearward in the fore-and-aft direction of the hull 111 with respect to the center 20e of the mast 20 in the left-and-right direction of the hull 111, it is possible to prevent the base guide members 60 from interfering with the movement of passengers in the fore-and-aft direction of the hull 111.

[0051] Furthermore, in this embodiment, as described above, the base guide member 60 supports and guides the base member 40 via the base moving member 61 that is movable along the arc-shaped base guide member 60. This allows the arc-shaped base guide member 60 to easily guide and support the base member 40 by the base moving member 61 that is movable along the arc-shaped base guide member 60.

[0052] In this embodiment, as described above, the base guide member 60 is a rail formed in an arc shape. The base moving member 61 is a roller member that is movable along the arc-shaped rail. This makes it possible to easily realize a configuration in which the base guide member 60 supports the base member 40 while guiding it via the base moving member 61 that is movable along the arc-shaped base guide member 60.

[0053] As described above, in this embodiment, the sailing device 100 includes an arc-shaped boom guide member 80 that is disposed rearward of the base member 40 in the fore-and-aft direction of the hull 111, connected to the tip 30b of the boom 30, and that guides and supports the boom 30 when the base member 40 rotates in a plane perpendicular to the up-and-down direction of the hull 111. This allows the arc-shaped boom guide member 80, which is connected to the tip 30b of the boom 30 and supports and guides the boom 30, to easily rotate the base member 40 in a plane perpendicular to the up-and-down direction of the hull 111. Furthermore, because the boom guide member 80 is disposed forward or rearward of the base member 40 in the fore-and-aft direction of the hull 111 and is connected to the tip 30b of the boom 30, the boom guide member 80 is unlikely to be positioned in the center of the hull 111 in the fore-and-aft direction. This prevents the boom guide member 80 from interfering with passenger movement in the fore-and-aft direction of the hull 111.

[0054] Furthermore, in this embodiment, as described above, the sail 10 includes the rear sail 12 that is disposed on the rear side in the fore-and-aft direction of the hull 111. The boom 30 also includes the rear boom 32 that supports the rear sail 12. The boom guide member 80 is connected to the tip 32b of the rear boom 32, and is disposed on the rear side in the fore-and-aft direction of the hull 111 relative to the base member 40. As a result, the boom guide member 80 is disposed on the rear side in the fore-and-aft direction of the hull 111 relative to the base member 40, and therefore the boom guide member 80 is easily disposed on the rear side in the fore-and-aft direction of the hull 111. This makes it possible to prevent the boom guide member 80 from obstructing the passengers' forward field of vision in the fore-and-aft direction of the hull 111.

[0055] Furthermore, in this embodiment, as described above, the boom guide member 80 supports and guides the boom 30 via the boom moving member 81 that is movable along the arc-shaped boom guide member 80. This allows the boom moving member 81 that is movable along the arc-shaped boom guide member 80 to easily guide and support the boom 30 on the arc-shaped boom guide member 80.

[0056] Furthermore, in this embodiment, as described above, the boom guide member 80 is a rail formed in an arc shape. The boom moving member 81 is a bearing member that is movable along the arc-shaped rail. This makes it possible to easily realize a configuration in which the boom guide member 80 supports and guides the boom 30 via the boom moving member 81 that is movable along the arc-shaped boom guide member 80.

[0057] Furthermore, in this embodiment, as described above, the mast 20 has an inverted V shape in which the two mast sections 20a gradually approach each other toward the upper end 20b of the mast 20. This eliminates the need to provide a separate wire for supporting the two mast sections 20a in the direction in which the two mast sections 20a are aligned, thereby simplifying the device configuration and eliminating the need for adjusting the wires.

[0058] Furthermore, in this embodiment, as described above, the boom 30 has an inverted V shape in which the two boom sections 30a gradually approach each other toward the tip 30b of the boom 30. This eliminates the need to provide a separate wire for supporting the two boom sections 30a in the direction in which the two boom sections 30a are aligned, thereby simplifying the device configuration and eliminating the need for adjusting the wire.

[0059] In this embodiment, as described above, the sail 10 includes a front sail 11 disposed on the front side of the hull 111 and a rear sail 12 disposed on the rear side in the fore-and-aft direction of the hull 111. The boom 30 includes a front boom 31 that supports the front sail 11 and a rear boom 32 that supports the rear sail 12. The rear end 31a of the front boom 31 is connected to the front end 40a of the base member 40. The front end 32a of the rear boom 32 is connected to the rear end 40b of the base member 40. As a result, the rear end 31a of the front boom 31 is connected to the front end 40a of the base member 40, so no load is applied to support the front boom 31 on the mast 20. This reduces the strength required of the mast 20 compared to when the rear end 31a of the front boom 31 is connected to the lower end 20d of the mast 20. Furthermore, because the front end 32a of the rear boom 32 is connected to the rear end 40b of the base member 40, no load is placed on the mast 20 to support the rear boom 32. This reduces the strength required of the mast 20 compared to when the front end 32a of the rear boom 32 is connected to the lower end 20d of the mast 20.

[0060] In this embodiment, as described above, the sailing device 100 is equipped with an actuator 50 that adjusts the rotation angle of the base member 40. This allows the actuator 50 to easily and automatically adjust the rotation angle of the base member 40.

[0074] In the above embodiment, the sailing device 100 is equipped with an actuator 50 that adjusts the rotation angle of the base member 40. However, the present invention is not limited to this. In the present invention, the sailing device does not necessarily have to be equipped with an actuator that adjusts the rotation angle of the base member. That is, the sailing device 200 of the boat 210 according to the modified example shown in FIG. 7 may be configured so that the rotation angle of the base member 40 can be adjusted manually. As shown in FIG. 7, the sailing device 200 of the boat 210 is equipped with a pair of winches 250 that adjust the rotation angle of the base member 40. One and the other of the pair of winches 250 are located on the left and right sides of the boom moving member 81 in the transverse direction of the hull 211, respectively. One and the other of the pair of winches 250 are located near the ends of the boom guide member 80 in the arc direction. As shown in FIG. 8, each of the pair of winches 250 is configured to reel in a rope 251 (see FIG. 7). As shown in Fig. 7, one of the pair of winches 250 is configured to be able to take up a rope 251 fixed to one of the two bearing members (boom moving members 81). The other of the pair of winches 250 is configured to be able to take up a rope 251 fixed to the other of the two bearing members (boom moving members 81). When one of the pair of winches 250 takes up the rope 251 fixed to one of the two bearing members (boom moving members 81), the bearing member rotates to one side in the arc direction of the boom guide member 80. When the other of the pair of winches 250 takes up the rope 251 fixed to the other of the two bearing members (boom moving members 81), the bearing member rotates to the other side in the arc direction of the boom guide member 80. As the bearing member (boom moving member 81) rotates in the arc direction of the boom guide member 80, the boom 30 (and thus the base member 40) fixed to the boom moving member 81 rotates around the rotation center axis C in a plane perpendicular to the vertical direction of the hull 211.
