Inflatable watercraft
The present invention provides inflatable watercraft that are light weight, easily stowed in relatively small spaces and formed from inflatable drop stitch panels. A preferred watercraft is a boat having a bow, stern, keel and an open transom for self-bailing. A deck can be provided as a separate panel that is cither permanently, or detachably, connected to freeboard sides of the watercraft. When connected, the deck provides a sitting area, and enhances the strength and rigidity of the watercraft by functioning like a deck beam. Optional features include a bucket held in place by, and fitted through, a hole in the deck panel. Preferred inflation pressures are between 2 and 25 p.s.i., and more preferably between 12 and 18 p.s.i.
1. An inflatable watercraft comprising:
an inflatable bottom panel having a port side and a starboard side, a bow end and a stern end, and a bottom surface;
an inflatable port side freeboard panel having a bow end and a stern end, and being connected to the port side of the bottom panel;
an inflatable starboard side freeboard panel having a bow end and a stern end, and being connected to the starboard side of the bottom panel;
the port side freeboard panel and the starboard side freeboard panel converging at their respective bow ends, and terminating substantially parallel to each other at their stern ends to define an open transom;
a first fabric strip overlapping a span between a lower outside surface of the port side freeboard panel and the bottom surface of the bottom panel;
a second fabric strip overlapping a span between a lower outside surface of the starboard side freeboard panel and the bottom surface of the bottom panel; and
an inflatable deck panel connected to and extending between the port side freeboard panel and the starboard side freeboard panel, wherein the deck panel, the bottom panel, the port side panel and the starboard side panel define a bow and a stern, a seating area approximately at midships.
2. The inflatable watercraft of claim 1 , wherein the starboard side freeboard panel and the port side freeboard panel are permanently affixed to the bottom panel by an adhesive, stitching, or a combination of adhesives and stitching.
3. The inflatable watercraft of claim 1 , wherein the open transom extends in height from an upper surface of the bottom panel to a lower surface of the deck panel, and in width from an inner surface of the port side freeboard panel to an inner surface of the starboard side freeboard panel, whereby water entering the watercraft drains by gravity out through the open transom.
4. The inflatable watercraft of claim 1 , wherein the deck panel includes means for holding objects to an upper surface of the deck panel.
5. The inflatable watercraft of claim 1 , wherein the bottom panel, the starboard side freeboard panel, the port side freeboard panel, and the deck panel are each made of inflatable drop stitch material.
6. The inflatable watercraft of claim 5 , wherein the bottom panel, the starboard side freeboard panel, the port side freeboard panel, and the deck panel are each airtight inflatable chambers having an inflation value for inflating each chamber to a pressure of between 2 and 25 p.s.i.
7. The inflatable watercraft of claim 1 , wherein the deck panel includes an opening adapted to hold a bucket fitting in the opening.
8. The inflatable watercraft of claim 1 , further comprising a plate disposed at the bow and connected between the starboard side freeboard panel and the port side freeboard panel, and extending from a gunwale of the bow to at least the waterline of the watercraft.
9. The inflatable watercraft of claim 8 , wherein the plate is made of rigid plastic material to which ends of the respective freeboard panels is affixed, and the plate extends from the gunwale down to the waterline, and rearwardly at least partially along the centerline of a keel.
10. An inflatable watercraft comprising:
an inflatable bottom panel having a port side and a starboard side, a bow end and a stern end, and a bottom surface;
an inflatable port side freeboard panel having a bow end and a stern end, and being connected to the port side of the bottom panel;
an inflatable starboard side freeboard panel having a bow end and a stern end, and being connected to the starboard side of the bottom panel;
the port side freeboard panel and the starboard side freeboard panel converging at their respective bow ends, and terminating substantially parallel to each other at their stern ends to define an open transom;
a first fabric strip overlapping a span between a lower outside surface of the port side freeboard panel and the bottom surface of the bottom panel; and
a second fabric strip overlapping a span between a lower outside surface of the starboard side freeboard panel and the bottom surface of the bottom panel;
wherein the bottom panel, the port side panel and the starboard side panel define a bow and a stern.
11. The inflatable watercraft of claim 10 , further comprising an inflatable deck panel detachably connected to and extending between the port side freeboard panel and the starboard side freeboard panel, the deck panel including a seating area approximately at midships of the watercraft.
12. The inflatable watercraft of claim 11 , wherein the deck panel includes an opening sized and positioned to hold a container resting on an upper surface of the bottom panel and extending through the deck panel.
13. The inflatable watercraft of claim 11 , further comprising a seat back panel pivotably connected to an upper surface of the deck panel.
14. The inflatable watercraft of claim 10 wherein all panels are made of a drop stitch material.
