Abstract
Abstract An aquatic board construction for sail boards, surf boards and the like has shaped upper and lower sections which are joined together with a generally hollow interior. Each section has a sandwich construction with high strength outer and inner skins, and a core formed from a filler material sandwiched between the two skins. The skins are preferably formed from multiple layers of a thermosetting resin impregnated into a fabric material. The outer skins extend beyond the sandwich construction of each section, with the two sections joined together along the extended portions of their outer skins. Receivers for accessories such as a fin, mast and the like are formed integrally with the board structure. The receivers have transverse flanges which are lodged between the inner and outer skins to retain the receivers in place. Structural webs having a similar sandwich construction to the board sections may be provided through the hollow interior of the board. The completed board is high strength yet light weight.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
An aquatic board comprising: shaped upper and lower sections joined together to form a board with a generally hollow interior, each section having a generally sandwich construction with a high strength outer skin, an inner skin spaced inwardly from the outer skin, and a core formed from a filler material sandwiched between the inner and outer skins, and a receiver for a board accessory such as a fin or a mast in at least one of said sections, said receiver comprising a main body portion having an outward facing receiver slot and extending inwardly into the generally hollow interior of the board, and a pair of opposed flanges extending transverse to the main body portion and lodged between the inner and outer skins, said flanges retaining the receiver in place between said inner and outer skins, said inner skin formed from a high strength material, and said outer skin having an opening aligned with said receiver slot.
Claim 2
Dependent Claim
157 words
An aquatic board comprising: shaped upper and lower sections joined together to form a board with a generally hollow interior, each section having a generally sandwich construction with a high strength outer skin, an inner skin spaced inwardly from the outer skin, and a core formed from a filler material sandwiched between the inner and outer skins, and a receiver for a board accessory such as a fin or a mast in at least one of said sections, said receiver comprising a main body portion having an outward facing receiver slot and extending inwardly into the generally hollow interior of the board, and a pair of opposed flanges extending transverse to the main body portion and lodged between the inner and outer skins, said flanges retaining the receiver in place between said inner and outer skins, said inner skin formed from a high strength material, and said outer skin having an opening aligned with said receiver slot.
Claim 3
Dependent Claim
