Abstract
Abstract A catamaran power boat has two spaced apart hulls interconnected by a substantially flat deck. Straddle-type pedestal seating is provided along the fore and aft center line of the deck with a handlebar-type steering mechanism located at the forward portion of the seating facility. Each hull has a substantially vertical step located approximately one-third of the distance from the aft portion of same. Hydraulic controls operate trim tabs to help the vessel regain a planing attitude during the various stages of the operation thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
A boat having two spaced apart hulls interconnected by a substantially flat deck, said boat comprising: at least one seating means substantially centered along the longitudinal center line of said deck, said seating means extending above the horizontal plane of said deck and adaptable to be straddled, said hulls each having a substantially vertical step therein at a location approximately one-third of the length of said hulls, said step dividing the lower surface of each hull into two adjacent surfaces lying in substantially parallel planes, and means for facilitating the movement of said hulls from an attitude where both adjacent surfaces contact the water to a planing position with substantially only that portion of said hulls forward of said step in said water contacting position.
Claim 2
Dependent Claim
125 words
A boat having two spaced apart hulls interconnected by a substantially flat deck, said boat comprising: at least one seating means substantially centered along the longitudinal center line of said deck, said seating means extending above the horizontal plane of said deck and adaptable to be straddled, said hulls each having a substantially vertical step therein at a location approximately one-third of the length of said hulls, said step dividing the lower surface of each hull into two adjacent surfaces lying in substantially parallel planes, and means for facilitating the movement of said hulls from an attitude where both adjacent surfaces contact the water to a planing position with substantially only that portion of said hulls forward of said step in said water contacting position.
Claim 3
Dependent Claim
39 words
The invention as in claim 1, wherein said boat includes a motor mounted on same, same being operable to propel said boat through the water, and means for protecting sad motor from turbulence as said boat is being propelled.
Claim 4
Dependent Claim
45 words
The invention as in claim 2, wherein said boat includes a motor well located adjacent the aft portion of same and wherein said protecting means includes a motor fairing interconnected with said motor well and positioned forwardly of the location normally occupied by said motor.
Claim 5
Dependent Claim
88 words
The invention as in claim 2, wherein said boat includes a handlebar steering mechanism located at the forward end portion of said seating means, said handlebar interconnected by a mechanical linkage with said motor and operable to position said motor for steering purposes in accordance with the movement of said handlebar mechanism, said motor linkage including a means for facilitating the control of the steering movement of said motor so that relatively short ratio turns of said handlebar steering mechanism positively controls the steering movement of said motor.
Claim 6
Dependent Claim
68 words
The invention as in claim 4, wherein said linkage between said motor and said handlebar steering mechanism includes a bellcrank pivotally movable in accordance with the movement of said handlebar steering mechanism, a steering cable interconnected with said motor, a rod means interconnected with said bellcrank and contacting said steering cable to efFect the movement of said steering cable and said motor with the movement of said bellcrank.
Claim 7
Dependent Claim
46 words
The invention as in claim 1, wherein said hull planing means includes at least one trim tab hingedly connected to said boat and hydraulic means for positioning sad trim tab in an optimum position to move said boat onto the forward planing surfaces of said hulls.
Claim 8
Dependent Claim
62 words
The invention as in claim 6, wherein said boat includes at least one trim tab adjacent the rear end extremity of each of said hulls, and wherein said hydraulic means has a foot pedal located adjacent said seating means, said foot pedal operable to operate a hydraulic ram associated with each trim tab in accordance with the position of said foot pedal.
Claim 9
Dependent Claim
51 words
The invention as in claim 7, wherein said trim tabs are movable to any water contacting operating position each time said foot pedal is fully depressed, said trim tabs having three operable water contacting positions, each of which results in the movement of said boat to the forward hull planing position.
Claim 10
Dependent Claim
45 words
The invention as in claim 1, wherein said boat includes a keel plate located at each step position of said hulls said keel plate operable to obviate sliding of the boat as the turns are negotiated or to maintain a steady course with minimum drift.
Claim 11
Dependent Claim
86 words
The invention as in claim 1, wherein said boat includes a foldable ladder fixedly attached to same, said ladder including a horizontal rod fixedly attached to said boat, at least two brackets pivotally attached to said rod, said brackets having at least two contacting surfaces wherein one of said surfaces contacts a contacting rod fixedly attached to said first mentioned rod when in a folded-up condition and said other of said contacting surfaces contacting the lower portion of said contacting rod when in a folded-down position.
