ABSTRACT:
A trolley for use in transporting, and particularly launching, a boat comprises a channel-sectioned hard rubber block which, in use, straddles the keelplate of the boat, and two-part rollers rotatable on opposite ends of a spindle which extends through the block. The trolley is secured to the keelplate by a slideable U-shaped detent element, the upper limb of which can be passed through registering holes in the side flanges of the block and in the keelplate. Various alternative detent arrangements may be employed.
