[1][2][3][4][5][6] The design was built by W. D. Schock Corp and by C/S/K Catamarans in the United States, from 1970 to 1972, with 12 boats completed, but it is now out of production.

[1][2][7][8][9][10] The Polynesian Concept is a recreational sailing catamaran, built predominantly of fiberglass, with wood trim.

The hulls have raked stems, reverse transoms, dual transom-hung rudders controlled by a tiller and twin retractable daggerboards.

[1][2] The boat has a draft of 1.58 ft (0.48 m) with the daggerboards retracted, allowing operation in shallow water or beaching.

[2] Ebsen wrote a book, Polynesian Concept, published by Prentice-Hall in 1972, about sailing the wooden prototype with a professional crew in the 1968 Transpacific Yacht Race from Los Angeles to Honolulu, winning against a field of eight mutihulls on corrected time.
