ABSTRACT:
A sail boat mast deck sealing assembly to provide a watertight seal between the mast and the boat deck is described. The assembly comprises a rigid flange member or collar formed in the same shape as the mast which is usually non-circular. The flange member has a triangular groove between the inner portion of the flange member and the mast. A triangular resilient member is placed in the triangular groove with the base portion protruding above the upper surface of the flange. A rigid cap ring is fastened to the flange and, with pressure, forces the triangular resilient member in the triangular groove thereby forming a watertight seal between the flange member and the mast.
