Abstract
Abstract The invention is a high-speed, planing sailboat having an elongated main body portion supported on two longitudinally spaced bouyant hull members and having two stabilizing outrigger pontoons supported laterally of the body by a pair of transverse beams. The hull members are spaced below the body and are pivoted to permit pitching movement. Independent biasing of the hulls into a predetermined angle of attack is accomplished by spring and shock absorber assemblies connected between the respective hulls and the body, and a pair of form-fitting shells or chairs are mounted laterally of the body to permit single-sailor operation of the boat on opposite tacks without the use of a hiking harness.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
104 words
A twin hulled outrigger sailboat comprising: a. an elongated body; b. a forward water-contacting laterally centralized substantially longitudinally extended hull member mounted in substantial vertical alignment with and beneath a forward portion of said body; c. an after water-contacting substantially longitudinally extended hull member mounted in substantial vertical alignment with and beneath a rear portion of said body and being substantially longitudinally aligned with and located in substantially the same horizontal plane as said forward hull member; d. a pair of outrigger pontoons mounted independently of said forward and after hull members and mounted to opposite sides of said body in spaced relation thereto.
Claim 2
Dependent Claim
104 words
A twin hulled outrigger sailboat comprising: a. an elongated body; b. a forward water-contacting laterally centralized substantially longitudinally extended hull member mounted in substantial vertical alignment with and beneath a forward portion of said body; c. an after water-contacting substantially longitudinally extended hull member mounted in substantial vertical alignment with and beneath a rear portion of said body and being substantially longitudinally aligned with and located in substantially the same horizontal plane as said forward hull member; d. a pair of outrigger pontoons mounted independently of said forward and after hull members and mounted to opposite sides of said body in spaced relation thereto.
Claim 3
Dependent Claim
33 words
Structure according to claim 1 wherein each of said hull members is spaced beneath said body and pivotally mounted thereto to permit each of said hull members to pitch relative to said body.
Claim 4
Dependent Claim
21 words
Structure according to claim 2 and including means to separately bias each of said hull members to a predetermined pitch angle.
Claim 5
Dependent Claim
46 words
Structure according to claim 1 and including a pair of rigid, immobile supports mounted laterally on the body on opposite sides thereof, said supports being laterally spaced from said body and each support comprises a shell substantially form-fitted to the contours of the sedentary human body.
Claim 6
Dependent Claim
69 words
Structure according to claim 4 wherein at least one of said hull members is provided with a rudder, and including a steering mechanism operably connected to said at least one rudder, said steering mechanism including a pair of substantially oppositely-directed bars joined to a steering post journalled to said body, each of said bars extending generally toward one of said shells and being accessible to a person seated therein.
Claim 7
Dependent Claim
45 words
Structure according to claim 1 wherein the water-contacting surface of said hull members are disposed at a level beLow the water contacting surfaces of said pontoons, when the boat is in non-heeling position, whereby when heeling the windward pontoon is raised free of the water.
