Patent ID: 7418911

Claim:
A trailerable sailboat comprising: a. a pivoting mast connected to said trailerable sailboat at one end wherein said connected end of said pivoting mast is rotatable about a first axis, wherein said first axis is substantially horizontal and is oriented substantially perpendicular to said trailerable sailboat's lengthwise centerline, b. wherein said pivoting mast weighs at least 25 pounds, c. wherein said trailerable sailboat is dimensionally reduced by lowering said pivoting mast to a substantially horizontal position for transportation on overland public roadways, d. a plurality of shrouds, wherein said shrouds stabilize said pivoting mast motion about said first axis, wherein one end of each of said shrouds terminates substantially in line with said first axis, e. a boom which is attached to said trailerable sailboat at an attached end using a mechanical attachment, wherein said attached end of said boom is attached to said trailerable sailboat separately from said pivoting mast, f. wherein said mechanical attachment allows said attached end of said boom to rotate about a second axis which is substantially vertical and a third axis which is substantially horizontal, g. wherein said boom is used to move said pivoting mast between substantially horizontal and substantially vertical positions, h. wherein said boom is mechanically restrained to rotate only about said third axis when said boom is used to move said pivoting mast between substantially horizontal and substantially vertical positions, i. wherein said third axis is substantially parallel to said first axis when said boom is used to move said pivoting mast between substantially horizontal and substantially vertical positions, j. wherein said boom is used as a sailing boom for at least one sail on said pivoting mast, k. wherein said trailerable sailboat is ramp launchable free of the use of a lifting crane, and l. wherein said mechanical attachment incorporates a plurality of stabilizing clamps for the purpose of providing additional said mechanical restraining of said boom to rotate only about said third axis, wherein said stabilizing clamps operate between two positions: i. a first position useful for normal sailing, wherein said stabilizing clamps provide no restriction of movement of said boom, and ii. a second position useful to stabilize the movement of said boom, wherein said stabilizing clamps allow said boom to substantially rotate only about said third axis.
