Abstract: The trailer gear serves to tow a water-craft on the ground. This gear comprises a tow bar and two separate wheel assemblies. The tow bar is adapted to be rigidly and detachably secured directly to the bow of the hull of the craft and serves to hitch the hull to the back of a towing vehicle. Each wheel assembly includes a rigid frame carrying a spring suspension, to the outer end of which is mounted a ground-engaging wheel. Each frame is adapted to be rigidly attached to a respective side wall of the hull. When the craft is in water, each wheel assembly, together with the towing bar, can be easily detached from the hull and put inside the latter. The invention further discloses a protecting cover for the cockpit of the hull of a water-craft having a front deck. This protecting cover is provided on the inside with foldable legs engageable with the bottom of the hull to retain the cover in raised position over the cockpit to form a shelter against rain. Furthermore, the cockpit cover is convertible into a tent.
