Abstract
A motor mount bracket for use in combination with a twin-hull sail boat, to which an outboard motor can be affixed, and which can support the motor in a running location with its screw in the water between the hulls, or in a stowed location with its screw out of the water. The bracket has a stand-off for attachment to the aft-most cross-strut of the sail boat, and an arm pivotally connected at its forward end to the stand-off at a pivot-point that is below and somewhat aft of the cross-strut. A motor mount is at the aft-end of the arm. The arm pivots through a vertical sweep between the running location and the stowed location.

A motor mount bracket for use in combination with a twin-hull sail boat of the kind having first and second pontoons spaced parallel to each other by at least a first forward cross-strut and a second aft-most cross-strut to which the pontoons are rigidly attached, each pontoon extending a distance aft from the second strut and having first and second rudders pivotally connected to the aft-end of each pontoon, respectively, first and second rudder control arms extending from said first and second rudders, respectively, forward toward said second strut, and an elongated tiller link extending parallel to said second strut pivotally connected at first and second separated points to the forward ends of said first and second control arms, respectively, for moving said rudders in unison around their respective pivots, said forward connecting points and said rudder pivots defining the four corners of a parallelogram in which said tiller link is movable between a first position closely adjacent said second strut when said rudders are set dead ahead, and a second position further aft from said second strut when said rudders are set for a turn;
- said motor mount bracket comprising a stand-off intended to be fixed to said second cross-strut between the pontoons, said stand-off when so affixed extending below and aft of said second cross-strut and providing a mount pivot located below and aft of said second cross-strut and below said tiller link, rigid motor support means including an arm pivotally attached at a forward point to said stand-off at said mount pivot, said arm extending aft from said mount pivot and having fixed to it a mount for an outboard motor, said mount being located a prescribed distance aft from said mount pivot which prescribed distance is substantially less than the distance aft from said second cross-strut to said rudder pivots but sufficiently far aft from said second cross-strut to hold an outboard motor clear of said tiller link in said second position.
A motor mount bracket for use in combination with a twin-hull sail boat of the kind having first and second pontoons spaced parallel to each other by at least a first forward cross-strut and a second aft-most cross-strut to which the pontoons are rigidly attached, said motor mount bracket comprising a stand-off intended to be fixed to said second cross-strut between the pontoons, said stand-off when so affixed extending below and aft of said second cross-strut and providing a mount pivot located below and aft of said second cross-strut, rigid motor support means including an arm pivotally attached at a forward point to said stand-off at said mount pivot, said arm extending aft from said mount pivot and having fixed to it a mount for an outboard motor, locating means on said stand-off to locate said arm in a first direction extending substantially horizontally relative to the water surface when said boat is afloat for holding an outboard motor in a running location when said motor is present on said mount, said locating means being operable to locate said arm in a second direction extending upward and aft from said mount pivot at an upward angle to the horizontal for holding said motor in a stowed location with its screw out of the water when said boat is afloat.
