Description
A watercraft
The invention relates to a watercraft comprising at least a hull and a deck connected to the hull along its circumference, whereby the hull and the deck are each provided with respective flanges, whereby the flanges are connected. to each other, which watercraft is further provided with at least one covering element positioned at a connection between the flanges,
Watercrafts are commonly provided with a hull being the watertight part of the watercraft and a deck being a permanent covering over the hull. To connect the hull and deck to each other in a watertight manner to prevent water to enter the watercraft, the hull and the deck can be provided with flanges, which flanges are connected to each other. To conceal the connection between the hull and the deck it is known to cover the connection with a covering element.
US5743204A discloses a watercraft whereby an edge trim is used to cover the area of junction between top (deck) and bottom (hull) members.
US6776u4B2 discloses a watercraft, whereby the watercraft body is constructed by joining a hull and a deck together at their peripheral regions and applying a protector strip of extruded material to the joint between the hull and the deck.
By these known watercrafts the connection between the hull and the deck are located outside the watercraft forming a bulky rim, whereby the covering element located on said connection further enhance the size of the bully rim.
The rim can easily be damaged since it extends at the most vunerable and widest part of the watercraft.
The edges of the flanges have often a bad tinish which need to be concealed.
Since the flanges extend at the outer side of the hull and deck, the flanges enlarge the width of the watercraft at the expense of the inner volume of the watercraft.
At least one of the objects of the invention is to provide a watercraft, like for example a yacht, whereby the connection between the hull and the deck is less bulky to provide a smoother transition between the hull and the deck.
This object is accomplished with the watercraft according to the invention in that the flanges extend towards the interior of the watercraft, whereby a first transition between the hull and its respective flange and a second transition between the deck and its respective flange form together a recess to accommodate the at least one covering element, wherein the flanges extending towards the interior of the watercraft are connected to each other.
Since the flanges extend towards the interior of the watercraft instead of to the outside as by the prior art watercraft, the flanges are not visible and do not form a bulky rim on the outside of the watercraft. Since the connection between the flanges is located insie the watercraft and not visible from the outside, the connection can be made with any combination of adhesive, welding, mechanical connections like bolts, nuts, pop rivets. If desired the flanges can be reinforced.
Furthermore, due to the recessed transitions forming a recess for the covering element, also the covering element does extend less outside the watercraft as the covering element by the known watercrafts. It is even possible to let the covering element being located completely inside the recess.
It has to be noticed that EP1157922A2 discloses a watercraft whereby first flanges extend towards the interior of the watercraft, whereby ends of the first flanges are provided with second flanges directed perpendicular to the first flanges and towards each other. Ends of the second flanges abut against each other. The surface over which the second flanges can be connected to each other is limited. By the watercraft according to the invention flat surfaces of the flanges extending towards the interior of the watercraft are connected to each other, so that larger surfaces can be connected to each other so that it is easier to obtain a watertight watercraft .
It has to be noticed that US2018001978A1 discloses a houseboat, whereby three panels are connected to each other by parts extending towards the interior of the watercraft. The hull part and the deck part are offset with respect to each other. US2018001978A1 does not disclose that the transition between a hull part and its respective flange and a transition between a deck part and its respective flange form together a recess to accommodated the at least one covering element.
An embodiment of the watercraft according to the invention is characterized in that the covering element is provided at at least one end with a tensioning element to tension the covering element against the first and second transition.
By means of the tensioning element the covering element can be pulled thigh in the recess and against the walls of the transitions.
Another embodiment of the watercraft according to the invention is characterized in that the recess formed by the first and second transition has an arcuate shape, preferably forming about half of a circle.
Due to the arcuate shape a smooth transition between the hull and the deck is obtained.
Another embodiment of the watercraft according to the invention is characterized in that the at least one covering element comprises a longitudinal tender provided with a centrally located wire, whereby the fender is tensioned in the recess by means of the wire.
The fender fulfils two purposes, firstly covering the connection between the hull and the deck and secondly forming a bumper to absorb kinetic energy of the watercraft when berthing against a jetty, quay wall or other vessel.
Since the fender is located in the recess, it is firmly being held against the watercraft without the risk that it will get loosen during surging waves during heavy seas.
Another embodiment of the watercraft according to the invention is characterized in that the fender comprises a tube, a guiding element located centrally inside the tube and spokes extending from a wall of the tube to the guiding element, whereby the wire is slideably located in the guiding element.
Due to the spokes the tube can easily move temporarily with respect to the guiding element when the fender bumps against another object like a jetty, quay wall or other vessel. The wire can easily slide with respect to the guiding element, during tensioning of the wire. In this manner a relatively simple but reliable fender is obtained. Each spoke can extend completely in the longitudinal direction of the fender or can extend over relatively short distances in the longitudinal direction with open spaces between adjacent spokes.
Another embodiment of the watercraft according to the invention is characterized in that the guiding element comprises a conduit.
The conduit extends along the whole fender so that the wire is supported along the whole fender by the conduit.
Another embodiment of the watercraft according to the invention is characterized in that the fender is a rope fender with a centrally located wire.
Besides being used as a fender and covering element, such a rope fender also has a decorative function to decorate the watercraft.
Depending on the wishes of a user the watercraft can be provided with a desired fender. It is also possible to change the fender if desired to provide the same watercraft with a different appearance.
