Abstract

A boat or dinghy can be dismantled into three longitudinal sections 26, 27 and 28 which are each divided transversely. Rigidity is maintained by staggering the transverse joints 22, 23, 24 and 25. The joints only protrude a few inches into the boat so that it is substantially hollow. When dismantled the sections nest into one another for compact storage or transporting. <IMAGE>

Description

SPECIFICATION Sectionalised boat This invention relates to a boat which is made in easily detachable sections which facilitate transport and storage of the boat and enable it to be assembled by unskilled labour at the place at which it is to be used.

An object of the invention is to provide a sectionalised boat which meets the requirements set out above and at the same time when assembled has the necessary inherent strength in its structure.

According to the invention a sectionalised boat comprises at least three detachable longitudinal sections divided by fore and aft joint lines, the longitudinal sections each being divided into at least two smaller sections by transverse joint lines, the transverse joint line or lines in the outboard longitudinal sections being staggered with respect to the transverse joint line or lines in the inboard longitudinal section.

Preferably the outboard longitudinal sections are each divided into two smaller sections by a transverse joint line and the inboard longitudinal section is divided into three or more smaller sections by transverse joint lines.

The joint lines may be formed as flanges which may protrude only a small distance, e.g. 50-100 mm into the hull of the boat.

Preferably the sections are so designed as to be easily nestable. For example the outboard longitudinal sections may be each divided into two smaller sections, one of which, e.g. the bow section, will nest within the other, and the inboard longitudinal section may be divided into three smaller sections which will partially fit within each other and in turn will fit within one of the larger outboard sections.

Thus, by arranging the dimensions to allow this nesting of the sections, it is possible for the whole boat to be reduced to occupy the volume of only two of the smaller sections of an outboard longitudinal section when packed for transport.

Preferably the sections are arranged to be bolted together by easily removable nuts and bolts and joints may be sealed with rubber or similar caulking as necessary.

A deck may be provided as part of the bow section and a removable deck section may be fitted along the inboard or central longitudinal section.

The invention is now described by way of example with reference to the accompanying drawings in which: Figure 1 is a plan of a boat embodying the present invention; and Figure 2 is a section on the centre line of the boat indicated by the arrows A-A.

The boat shown in the drawing comprises a number of sections which are bolted together.

There are two main longitudinal outboard sections 10 and 11 and an inboard longitudinal section 1 2. Fore and aft joint lines 1 3 and 14 divide the longitudinal sections. The outboard longitudinal section 10 is in turn divided into two smaller sections 1 5 and 1 6. Similarly the outboard longitudinal section 11 is divided into two smaller sections 1 7 and 18. The inboard longitudinal section 1 2 is divided into three smaller sections 19, 20 and 21.

Transverse joint lines are provided between each of the sub-sections. For example subsections 1 5 and 1 6 are joined on a transverse joint line 22, sub-sections 1 7 and 1 8 are joined on a transverse joint line 23, subsections 1 9 and 20 are joined on a transverse joint line 24 and sub-sections 20 and 21 are joined on a transverse joint line 25. It will be noted that transverse joint lines 24 and 25 are staggered with respect to transverse joint lines 22 and 23. All the joint lines are in the form of flanges which extend a small distance, e.g, from about 50mm to 100mm up from the floor of the hull as shown in the section in Fig. 2.

Although shown as roughly equal in width the longitudinal sections are preferably unequal in the sense that the outer longitudinal sections comprising sub-sections 1 5 and 1 6 are wider than the inboard longitudinal sections i.e. the dimension 26 is less than the dimensions 27 and 28.

Because of the taper of the bow sections 1 6 and 18 as illustrated at 29 in Fig. 2 and because of the rake of the stern 30 it will be seen that section 1 8 will fit into section 1 7 in a nesting fashion. Similarly section 1 6 fits into section 1 5. The smaller sections of the inboard part of the boat will stack on each other and fit into one of the larger sections of the outboard part of the boat. Thus the whole boat can be reduced to two packages no larger than the largest of the outboard sections.

1. A sectionalised boat comprising at least three detachable longitudinal sections each being divided into at least two smaller sections by transverse joint lines, the transverse joint line or lines in the outboard longitudinal sections being staggered with respect of the transverse joint lines or line in the inboard longitudinal section.
