Pleasure craft having an improved deck construction
View Patent ↗A pleasure craft is provided such as a luxury pleasure craft. The craft eliminates the need for transverse bulkheads in one or more decks inside the hull of the craft, thus improving the aesthetics and usability thereof. The hull of the pleasure craft defines an imaginary or virtual freeboard deck located below the main deck of the craft. A cavity is arranged on one or more decks on both sides of the hull separate from the remaining space of the corresponding deck and delimited on its outer side by the corresponding side wall. The imaginary or virtual freeboard deck is therefore at a height equal to the extension in the vertical direction of the cavities from the floor of the corresponding deck.

a main deck and a hull, the hull having two opposite sides and two opposite side walls and an inner space between the opposite side walls,
wherein the opposite side walls of the hull are made of framing,
wherein the inner space of the hull is divided into a plurality of overlying decks, each overlying deck having a floor and an overall height from the floor and an overall width between the two opposite sides of the hull,
wherein the plurality of overlying decks include at least a lower deck located below the main deck and an underlying underlower deck located below the lower deck and immediately above a keel of the hull,
wherein, on the lower deck inside the hull, along each of the opposite sides of the hull, a lateral cavity is provided, which is separate from a remaining space of the corresponding lower deck,
wherein each lateral cavity has an outer side, an inner side, a lower side, and an upper side,
wherein each lateral cavity is delimited on its the outer side of the lateral cavity by a corresponding side wall of the hull and each lateral cavity is integral at the outer side with the corresponding opposite side wall of the hull and at the lower side of the lateral cavity with the floor of the lower deck,
wherein each lateral cavity extends vertically from the floor of the lower deck over a given vertical extension and at a given distance from the corresponding side wall of the hull,
wherein the given distance is less than half of the overall width of the lower deck, and the given vertical extension is less than the overall height of the lower deck,
wherein each lateral cavity is delimited on the outer side of the lateral cavity by the framing of the corresponding side wall of the hull,
wherein each lateral cavity is delimited on the inner side of the lateral cavity by an additional framing, which is provided at the given distance from the corresponding side wall of the hull and extends from the floor of the lower deck in a substantially vertical direction over the given vertical extension, and
wherein each lateral cavity is delimited on the upper side of the lateral cavity by a connecting framing which extends in a substantially horizontal direction between an upper end of the additional framing and the corresponding side wall of the hull, thus joining with the framing of the side wall of the hull, and
wherein each lateral cavity is communicating at the lower side of the lateral cavity with one or more underlying watertight compartments provided between the lower deck and the underlying underlower deck.
2 . The pleasure craft according to claim 1 , wherein the hull has a longitudinal axis and each lateral cavity has a longitudinal direction parallel to the longitudinal axis of the hull, and wherein each lateral cavity is divided along the longitudinal direction into separate compartments by means of transverse bulkheads.
3 . The pleasure craft according to claim 1 , wherein a height of the given vertical extension is between 10% and 70% of the overall height of the lower deck.
4 . The pleasure craft according to claim 3 , wherein the height of the given vertical extension is between 20% and 50% of the overall height of the lower deck.
5 . The pleasure craft according to claim 1 , wherein each lateral cavity has a width between 1% and 10% of the overall width of the lower deck.
6 . The pleasure craft according to claim 5 , wherein the width of each lateral cavity is between 2% and 5% of the overall width of the lower deck.
7 . The pleasure craft according to claim 1 , wherein the lower deck is made without transverse bulkheads.
8 . The pleasure craft according to claim 1 , wherein the pleasure craft is a yacht.
9 . A pleasure craft, comprising:
a main deck and a hull, the hull having two opposite sides and two opposite side walls and an inner space between the opposite side walls,
wherein the opposite side walls of the hull are made of framing,
wherein the inner space of the hull is divided into a plurality of overlying decks, each overlying deck having a floor and an overall height from the floor and an overall width between the two opposite sides of the hull,
wherein the plurality of overlying decks include at least a lower deck located below the main deck and an underlying underlower deck located below the lower deck and immediately above a keel of the hull,
wherein, on the lower deck inside the hull, along each of the opposite sides of the hull, a lateral cavity is provided, which is separate from a remaining space of the corresponding lower deck,
wherein each lateral cavity has an outer side, an inner side, a lower side, and an upper side,
wherein each lateral cavity is delimited on the outer side of the lateral cavity by a corresponding side wall of the hull and each lateral cavity is integral at the outer side with the corresponding opposite side wall of the hull and at the lower side of the lateral cavity with the floor of the lower deck,
wherein each lateral cavity extends vertically from the floor of the lower deck over a given vertical extension and at a given distance from the corresponding side wall of the hull,
wherein the given distance is less than half of the overall width of the lower deck, and the given vertical extension is less than the overall height of the lower deck,
wherein each lateral cavity is delimited on the outer side of the lateral cavity by the framing of the corresponding side wall of the hull,
wherein each lateral cavity is delimited on the inner side of the lateral cavity by an additional framing, which is provided at the given distance from the corresponding side wall of the hull and extends from the floor of the lower deck in a substantially vertical direction over the given vertical extension, and
wherein each lateral cavity is delimited on the upper side of the lateral cavity by a connecting framing which extends in a substantially horizontal direction between an upper end of the additional framing and the corresponding side wall of the hull, thus joining with the framing of the side wall of the hull, and
wherein each lateral cavity is watertight.
10 . The pleasure craft according to claim 9 , wherein the hull has a longitudinal axis and each lateral cavity has a longitudinal direction parallel to the longitudinal axis of the hull, and wherein each lateral cavity is divided along the longitudinal direction into separate compartments by means of transverse bulkheads.
11 . The pleasure craft according to claim 9 , wherein a height of the given vertical extension is between 10% and 70% of the overall height of the lower deck.
12 . The pleasure craft according to claim 11 , wherein the height of the given vertical extension is between 20% and 50% of the overall height of the lower deck.
