ABSTRACT:
The trailer has a main frame of generally U shape having stub axles on which ground-engaging wheels are journalled. A structurally rigid boat supporting frame is suspended from the main frame by a cable and pulley arrangement which enables the boat supporting frame to be raised and lowered horizontally and to be tilted lengthwise to a relatively steep angle relative to the main frame. The desired degree of tilt is facilitated by the fact that the front end of the boat supporting frame can be pivotally connected to the main frame at various heights.
