Problems solved by technology

Another disadvantage is that it is not easy to provide a relatively large number of air chambers in an efficient manner: this is because for each air chamber an additional partition wall needs to be welded to the bottom

Embodiment Construction

[0026] figure 1 The ship shown in perspective in FIG. 2 has a hull generally indicated by reference number 1 , which has an outer wall 2 . The bottom 3 is provided with a large number of air chambers 4 extending longitudinally of the hull 1 . like figure 2 As shown in the cross-sectional view in , the air chamber 4 is formed by the bottom 3 in the shape of a trapezoid. The trapezoid has a raised wall portion 5, a lowered wall portion 6, and a connecting wall portion 7 connecting the raised wall portion and the lowered wall portion. Each two connecting wall parts 7 and one raised wall part 5 delimits an air chamber 4 . In the transverse direction of the bottom 3, the spacing a remains constant. This means that the width of the raised walls 5 is equal to the width of the opening between said walls.

[0027] As a result of the use of a base shaped based on a trapezoidal profile, not only can a relatively large number of air cells 4 arranged next to each other be obtained, b...

Abstract

A vessel has a hull (1) provided with an outer wall (2), chambers (4) on the outside of the outer wall (2) that extend in the longitudinal direction of the hull (1) as well as means for supplying airto said chambers to lower the frictional resistance of the hull with respect to the body of water in which the hull can be located. At least one portion of the outer wall has, in cross section, a profile with wall sections (7) extending transversely to the transverse direction, such that in each case at least two wall sections (7) extending transversely to the transverse direction delimit a chamber (4).

Description

technical field [0001] The invention relates to a ship, the hull of which is provided with: a closed outer wall, which limits the displacement of the ship, air chambers located on the outside of the outer wall, which extend longitudinally along the hull and can be opened towards the body of water in which the ship is located, and air supply means for supplying air to said air chamber to reduce friction of the hull relative to the body of water Background technique [0002] One such boat is disclosed in NL-A 6815424 . The hull bottom of this known boat is provided with a collar which is oriented downwards and extends around a large part of the bottom. Inside the collar, three walls extend longitudinally of the base and are likewise oriented downwards, which together with the collar delimit four air chambers. These air chambers are in turn separated longitudinally by transverse walls. [0003] In this known boat, the walls forming the bottom are made flat in a conventional ...
