Abstract
A marine vessel provides a hull having a bow, stern, and port and starboard portions, and a hull bottom having port and starboard sides that form a vee shape. A channel extends longitudinally from the stern toward the bow a distance at least half the hull length, and can extend substantially the entire length of the hull. The bottom of the channel is defined in part by a portion of the hull bottom. The top of the channel is defined by one or more upper panels or surfaces that form catamaran hulls with the port and starboard sides of the hull bottom when the channel is filled with water in a non-planing hull position. The channel is above the water surface when the hull is in a planing position wherein the water drains from the channel.

- 1. Field of the Invention
- The present invention relates to marine vessels. More particularly the present invention relates to an improved marine vessel hull having an outer hull (e.g. deep vee) and a channel that extends longitudinally from the stern of the hull toward the bow a distance at least half the length of the hull, wherein the channel is defined by portions of the outer hull that are below the tunnel and one or more upper surfaces that form an inner and upper part of two catamaran hulls when the channel is filled with water in an off plane position.
- 2. General Background of the Invention
- Marine vessels commonly employ a “vee” or “deep vee” outer hull arrangement. A deep vee hull can be for example a hull having a deadrise of about 20-24 degrees.
- While deep vee hulls are smooth riding hulls in rough water and when on plane, they are not as stable as a catamaran style hull when they are not on plane. Patents have issued and applications have published for various hull designs. The following table lists examples. The order of listing has no significance other than chronological.

FIGS. 1-8 show preferred embodiments of the apparatus of the present invention designated generally by thenumeral 10. Marine vessel orboat 10 provides ahull 11. In the drawings, thenumeral 12 indicates the water surface. - Hull 11 has a
port side 13 and astarboard side 14. Hull 11 provides adeck 15 to accommodate one or more passengers.Deck 15 can be fitted with chairs, a pilot house, a center console, a steering column and or any other fitting or seating desired.Hull 11 provides gunwales including port gunwale 16 anstarboard gunwale 17. -
Hull 11 can have attached thereto or received thereon or therein one ormore propulsion units 18. In the drawings thepropulsion units 18 are outboard motors, though any appropriate propulsion units could be used, including for example inboard motors. Each of thepropulsion units 18 in the drawings includes apropeller 19. -
Hull 11 provides a hull vee or deep vee portion.Hull 11 provides abow 21 and stern 22. Thehull vee portion 20 provides akeel 23 at the intersection of hull bottom panels or surfaces 24, 25. The bottom surfaces 24, 25 define a hull vee and adeadrise 26 which is illustrated schematically inFIG. 3 . The hull deadrise is typically between about 15 and 30 degrees for a vee hull, more particularly between about 20 and 26 degrees for a hull deadrise for deep vee hull. -
Hull 11 has achannel 27 that extends longitudinally.Channel 27 is defined byhull bottom segments inner hull segments segments FIG. 2-3 . Theinner hull segments edge 32 as seen inFIG. 3 .Channel 27 is open athull 11 stern 22. Thestern opening 33 can be seen inFIGS. 2 and 3 . Thechannel 27 can be closed at the bow. - An
optional port 34 can provide an air opening through which air can enterchannel 27 whenhull 11 moves from the on plane or planing position ofFIG. 6 to the off plane position ofFIG. 4 . When thevessel hull 11 moves from the on plane position ofFIG. 6 to the off plane positionFIG. 4 , water enterschannel 27 viastern opening 33 and fills thechannel 27 as illustrated byFIG. 4 . Air can optionally exitchannel 27 viaport 34. - When the
hull 11 moves between the off plane position ofFIG. 4 and the on plane position ofFIG. 6 ,arrow 41 inFIG. 5 schematically illustrates a discharge of water fromchannel 27 viastern opening 33. Because the hull bottom surfaces 24, 25 are the “wetted surfaces” that rest upon thewater surface 12 when on plane,channel 27 will empty viastern opening 33. - The
channel 27 is filled viastern opening 33 when thehull 11 is off plane as shown ifFIGS. 2 , 3 and 4. In this position, theinner hull segments port catamaran hull 42 andstarboard catamaran hull 43 inFIG. 3 . The port catamaran hull is defined byinner hull segment 30 andbottom surface 24. Similarly, thecatamaran hull 43 is defined byinner hull segment 31 and thehull bottom surface 25. Thecatamaran hulls channel 27. Thechannel 27 is filled with water in the off plane position as shown inFIG. 3 so that buoyancy is only contributed by the portion ofhull 11 that is not flooded, namely theport 42 andstarboard 43 catamaran hulls. -
FIGS. 7-8 show alternate configurations for thechannel 27.Channel 35 shown isFIG. 7 includesinner hull segments FIG. 8 , thechannel 39 is defined by curved inner hull segment 40. - The vessel of the present invention can have inboards instead of outboards, in which case it might have jet drives or propellers. It can be outfitted with inflatable rubber bumpers (or bumpers made of other soft material, not necessarily inflatable), preferably on all sides and back, so that the vessel can be used for ship inspections and offshore platform inspections, spar buoy inspections and maintenance, spar-type platform inspections and maintenance, and semi-submersible platform inspections and maintenance. The vessel can also be outfitted with decompression chambers for use in surface supplied commercial diving operations using compressed air and mixed gas diving. The vessel can also be used to support scuba diving operations.
- The tunnel could extend throughout the vessel as shown, or it could terminate further back from the front of the vessel. For example, the tunnel could go from the stern to the forward bulkhead (also known as the crash bulkhead or the collision bulkhead).
