Benefits of technology

[0006] It is an object of this invention to provide a marine craft which is relatively stable and easily handled in rough water and permits the main body or hull of the craft to be minimally affected by waves. It is a further object of this invention to maximise the headroom available in the forward, interior, part of the boat.

Problems solved by technology

Catamarans are relatively stable but of necessity have flat floors and therefore do not have the interior area of a conventional monohull boat.

Embodiment Construction

[0020] A preferred embodiment of the invention is shown in FIGS. 1 to 4. The marine craft 10 of the invention is a marine craft having a hull 12 which is relatively conventionally shaped, in the form of mono-hull boats, except that its hull is effectively elevated above two lateral hull devices 14.

[0021] The hull has floors above and substantially across the lateral hull devices but which descend down into a third hull device 20, which is oriented along the centreline of the craft, which in the embodiment of the invention described here has a leading edge 21 which is effectively a continuation of the bow of the boat.

[0022] This third hull device 20 has an opening 22 into its interior and in this embodiment of the invention is substantially V shaped. As shown in FIG. 4 this hull device 20 can be provided with a floor 23 to provide a convenient platform upon which a person can stand. Irrespective of the improved handling characteristics provided by the central hull device, the fact ...

Abstract

A multi-hull marine craft includes two laterally spaced, wave-piercing side hulls, which extend for the length of the marine craft. In a forward portion of a tunnel extending between the two laterally spaced side hulls is a V-shaped third hull of less draught and length than the two lateral side hulls, but which is also of a wave-piercing shape. The V-shaped third hull, or central hull, may have a lowered floor affording additional headroom in the cabin of the marine craft.

Description

TECHNICAL AREA [0001] This invention relates to the area of the manufacture of marine craft and in particular to the development of craft which is stable and easily handled in adverse weather conditions while having an interior which is substantially similar to a conventional craft. BACKGROUND TO THE INVENTION [0002] For the purpose of improving stability and comfort when compared to mono-hull boats it is known for multi-hull boats such as catamarans and trimarans to be used. [0003] Catamarans are relatively stable but of necessity have flat floors and therefore do not have the interior area of a conventional monohull boat. [0004] Trimarans, having a central hull and two laterally positioned stabilising hulls are very stable however they extend across a large area while having relatively little useful space other than in the central hull. [0005] In addition trimarans have a significantly greater wetted surface area than a catamaran and consequently, although being fairly stable vess...
