<p>An apparatus in the form of a skeg linkage arm (10) is disclosed for decreasing yaw of a first vessel (12) when the first vessel is pulled by a second vessel (14) which may alternatively be positioned to lessen water resistance when the first vessel (12) is pushed by the second vessel (14). The apparatus includes a fin or skeg (20) movably secured to the first vessel (12) such thatthe fin (20) may be moved from a first position wherein the fin (20) is in the water to decrease yawto a second position wherein water resistance is lessened. The apparatus (10) may further provide a linkage (30) for coupling the first and second vessels (12 & 14) wherein the apparatus (10) permits freedom of movement of the first vessel (12) relative to the second (14) for pitching, heaving, and, if desired rolling motions when the vessels (12 & 14) are coupled and further functions as a skeg (20) for the first vessel (12) when the first (12) is pulled by second vessel (14).</p> |
