<p>The launching trolley has a set of tubular frame hoops (2,3) joined by longitudinal spars so that the boat can be floated into the frame and secured. After hauling out of the water the frame can be rolled onto the side to gain access to the hull and to tip out any water. The boat can also be stored upside down to keep it dry. The wheels (11) are removable to aid the rolling. The keel (7) is clamped between securing plates (8) on the frame. The trolley allows all types of small boats to be handled with ease.</p> |
