Benefits of technology

The invention proposes an inflatable boat that has a better hydrodynamic profile than previous examples, resulting in better gliding quality on water.

Problems solved by technology

There is a disconnection between the front part of the floor and the tubes, the effect of which is to generate a considerable draught, penalising the advance of the boat and jeopardising the gliding quality of the boat.
This type of boat therefore has a hydrodynamic profile which is ineffective.

Embodiment Construction

[0055]FIG. 1 shows an inflatable boat 10 according to the present invention. In this example, it is a boat of canoe or kayak type.

[0056]The boat 10 extends according to a longitudinal direction L, and classically has a front part called a prow, referenced 12, and a rear part, called a stern, referenced 14.

[0057]The prow 12 comprises a first bow 16 which will be described in more detail herein below.

[0058]In this example, the stern 14 substantially has the same form as the prow 12, such that the stern 14 further comprises a bow, called a second bow18, opposite the first bow. The boat 10 further comprises two inflatable lateral tubes 20, 22 which extend according to the longitudinal direction L of the boat 10, between the prow 12 and the stern 14. The length of the inflatable lateral tubes is substantially equal to the length of the boat.

[0059]Each of the lateral tubes 20, 22, also called “collar” or “sponson” has a substantially circular transversal cross-section. Each lateral tube h...

Abstract

The invention relates to a boat having a longitudinal direction, including a first bow, two inflatable lateral tubes extending according to the longitudinal direction of the boat, and an inflatable base arranged between the two inflatable lateral tubes. The inflatable base further comprises a floor portion, and at least one first pair of end portions extending from one of the two longitudinal ends of the floor portion. A fold line is formed between the floor portion and each of the end portions of the first pair, and when the inflatable base is in its inflated state, each end portion is in a position folded around the corresponding fold line to form the first bow of the boat.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to the field of boating, and more particularly that of inflatable boats.[0002]The invention relates especially, though not exclusively, to an inflatable boat of kayak, canoe, ship type or any other type of boat.[0003]The invention refers more particularly to a boat having a longitudinal direction and comprising:[0004]a first bow;[0005]two inflatable lateral tubes extending according to the longitudinal direction of the boat;[0006]an inflatable base arranged between the two lateral tubes.[0007]In terms of the invention, the first bow is preferably situated at the prow of the boat. The invention also covers a boat capable of navigating in both directions such that the first bow can also be arranged at the level of the stern of the boat according to the direction of navigation of the boat.[0008]Traditionally, the bow of such an inflatable boat is constituted by the ends in front of the lateral tubes which come into contact ...
