Abstract

Abstract This invention primarily resides in two float wings of substantially triangular contoured construction conforming to the hull of the boat securely affixed to the exterior stern of a fishing boat above the water line. Float wings may be constructed of expanded plastic having high buoyancy qualities such as expanded polystyrene or polyurethane. Any plastic producing a closed cell, rigid foam may be utilized. For durability, the foam is preferably covered with a fabric such as nylon reinforced vinyl or other suitable, durable fabric. The wings are securely attached to the hull of the boat with the base of the triangular structure projecting substantially normal to the hull. Auxiliary floats may be attached interior of the hull adjacent the bow to aid flotation and stability should the boat be swamped.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 291 words
Auxiliary floating gear for a fishing boat having a hull comprising: a. right and left elongated stern flotation wings adapted to be securely attached exteriorly adjacent the stern of said boat, said wings comprising rigid expanded plastic foam inner filler and a fabric float cover encasing said rigid foam filler; b. right and left bow flotation members adapted to be securely attached interior and adjacent the bow of said boat, said bow flotation members comprising rigid expanded plastic foam inner filler and a fabric float cover encasing said rigid foam filler; c. securing means for rigidly attaching said stern flotation wings and bow flotation members to said boat, said securing means comprising: (1) an adhesive to be positioned between said wings and said flotation members and said boat; (2) a grommet secured to said fabric float cover; (3) a float sleeve projecting through said expanded rigid foam filler; (4) a bolt projecting through said grommet and said float sleeve; (5) means for rigidly affixing said bolt to said boat comprising a bolt shoulder adjacent said boat, a sealing bushing encircling said bolt adjacent said bolt shoulder, a washer encircling said bolt adjacent said boat hull, and a nut threadably engaging said bolt thereby securely affixing said bolt to the structure of said boat; said right and left stern flotation wings being a substantially triangular construction, the height of said triangle following the contour of the hull of the boat adjacent the stern of the boat, the base of said substantially triangular float wings projecting substantially normal to the hull of said boat, and said right and left stern flotation wings being secured above the normal water line of the boat and projecting outward substantially normal to the hull of said boat.
Claim 2
Dependent Claim 291 words
Auxiliary floating gear for a fishing boat having a hull comprising: a. right and left elongated stern flotation wings adapted to be securely attached exteriorly adjacent the stern of said boat, said wings comprising rigid expanded plastic foam inner filler and a fabric float cover encasing said rigid foam filler; b. right and left bow flotation members adapted to be securely attached interior and adjacent the bow of said boat, said bow flotation members comprising rigid expanded plastic foam inner filler and a fabric float cover encasing said rigid foam filler; c. securing means for rigidly attaching said stern flotation wings and bow flotation members to said boat, said securing means comprising: (1) an adhesive to be positioned between said wings and said flotation members and said boat; (2) a grommet secured to said fabric float cover; (3) a float sleeve projecting through said expanded rigid foam filler; (4) a bolt projecting through said grommet and said float sleeve; (5) means for rigidly affixing said bolt to said boat comprising a bolt shoulder adjacent said boat, a sealing bushing encircling said bolt adjacent said bolt shoulder, a washer encircling said bolt adjacent said boat hull, and a nut threadably engaging said bolt thereby securely affixing said bolt to the structure of said boat; said right and left stern flotation wings being a substantially triangular construction, the height of said triangle following the contour of the hull of the boat adjacent the stern of the boat, the base of said substantially triangular float wings projecting substantially normal to the hull of said boat, and said right and left stern flotation wings being secured above the normal water line of the boat and projecting outward substantially normal to the hull of said boat.
