ABSTRACT:
A steerage wheel for a vessel such as a sailing yacht is disclosed. A rim member is attached to a hub member by a series of spokes. The rim member includes pivot mechanisms to allow sector portions of the rim member to be folded over to reduce the effective width of the steerage wheel. The spokes connecting the hub to the sector portions have releasable securing means to allow the connection between the rim member and the hub to be severed to permit folding of the steerage wheel without interference from the spokes. The releasable seeming means is a screw threaded sleeve that allows connection and detachment of the free ends of two lengths of the spoke.
