Abstract

Abstract A catamaran vessel adapted to receive a pickup truck camper body or a house trailer is provided with a detachable bow ramp and a stern pylon. A winch supporting dolly is connected to the socket hitch of the trailer or a wheeled frame supporting a camper. The winch cable is attached to the pylon and the winch used to pull the camper or trailer up the detachable bow ramp onto the deck. The forward control podium of the vessel swings out of the way during such loading. The socket hitch then is connected directly to the pylon to maintain the camper or trailer in place, and utility modules on the vessel are connected to the camper or trailer to allow it to be utilized while on board. These modules include, within one catamaran hull, a waste water holding tank which also serves as ballast if the camper or trailer is located off-center of the vessel. The fiberglass hulls of the vessel include outwardly flanged upper edges to which are bolted deck panels comprising a polyurethane core sandwiched between fiberglass or laminated wood sheets.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 222 words
A system for utilizing a conventional camper of the type mounted on a truck body as a houseboat, comprising: a vessel having a hull supported deck structure; a pylon mounted on said vessel adjacent the stern thereof; ramp means detachably connected to the bow of said vessel; a wheeled frame for supporting said camper when removed from said truck, said frame being generally triangular and including a vertically offset section adjacent one apex, a pair of wheels being attached to said frame adjacent the other two apices and mutually spaced by greater than a width dimension of said camper, said offset section including a third wheel and adjacent said apex, a socket hitch, said non-offset portion only being disposed to fit beneath said camper in attached supporting relationship therewith; and a wheeled dolly including a winch and cable, said dolly being attachable to said wheeled frame, said cable being attachable to said pylon, whereby winding said cable onto said winch causes said dolly, said frame, and said camper to be transported up said ramp means and onto said deck structure, said frame then being directly hitchable to said pylon. CM,2Tem according to claim 1 further comprising: a waste water holding tank mounted within one of said hulls; and means for connecting the waste water outlet of said camper to said holding tank.
Claim 2
Dependent Claim 38 words
A system according to claim 1 wherein said vessel includes a fresh water supply, 28 volt dc and 110 volt ac electrical supplies, and a used water holding tank for utilization of said camper while aboard said vessel.
Claim 3
Dependent Claim 162 words
A catamaran vessel adapted to rEceive thereon a camper or trailer, comprising: a pair of unitary, partially hollow hulls each having outwardly flanged upper peripheral edges; a plurality of planar deck members of length substantially equal to the width of said vessel, each deck member being fasteningly attached to said flanged edges; a detachable ramp for wheeling said camper or trailer across the bow of said vessel onto said deck members, said ramp including at least two planar ramp members each having upwardly flanged longitudinal edges, the underside of one end of each ramp member being provided with a downwardly opening, generally hemicylindrical member, the bow deck member being provided with a number of recesses along the forward edge thereof, a horizontal, ramp attaching cylindrical member being disposed in each such recess, the hemicylindrical member of each ramp member engaging the corresponding cylindrical member to attach said ramp to said vessel; and means for securing said camper or trailer to said vessel.
Claim 4
Dependent Claim 162 words
A catamaran vessel adapted to rEceive thereon a camper or trailer, comprising: a pair of unitary, partially hollow hulls each having outwardly flanged upper peripheral edges; a plurality of planar deck members of length substantially equal to the width of said vessel, each deck member being fasteningly attached to said flanged edges; a detachable ramp for wheeling said camper or trailer across the bow of said vessel onto said deck members, said ramp including at least two planar ramp members each having upwardly flanged longitudinal edges, the underside of one end of each ramp member being provided with a downwardly opening, generally hemicylindrical member, the bow deck member being provided with a number of recesses along the forward edge thereof, a horizontal, ramp attaching cylindrical member being disposed in each such recess, the hemicylindrical member of each ramp member engaging the corresponding cylindrical member to attach said ramp to said vessel; and means for securing said camper or trailer to said vessel.
Claim 5
Dependent Claim 52 words
A catamaran vessel according to claim 4 wherein mounted on said deck members or within a hull are utility services facilities connectable to said camper or trailer, said facilities further providing ballast for said vessel when said camper or trailer is situated on said vessel but offset from the longitudinal centerline thereof.
Claim 6
Dependent Claim 92 words
A catamaran vessel adapted to receive thereon a camper or trailer, comprising; a pair of partially hollow hulls; a planar deck structure disposed between said hulls, said camper or trailer adapted to be positioned on said deck structure and situated laterally off center, substantially above one of said hulls; a waste water holding tank positioned within the other of said hulls, whereby said waste water holding tank acts as ballast for said catamaran vessel; and means for connecting the waste water discharge outlet of said camper or trailer to said holding tank.
Claim 7
Dependent Claim 92 words
A catamaran vessel adapted to receive thereon a camper or trailer, comprising; a pair of partially hollow hulls; a planar deck structure disposed between said hulls, said camper or trailer adapted to be positioned on said deck structure and situated laterally off center, substantially above one of said hulls; a waste water holding tank positioned within the other of said hulls, whereby said waste water holding tank acts as ballast for said catamaran vessel; and means for connecting the waste water discharge outlet of said camper or trailer to said holding tank.
