Making a concrete boat using beach sand as both a form and a material is described in the 1971 edition of the The Whole Earth Catalog – Access to Tools, a compendium oninstructions, products and services already published or advertised elsewhere. This description was a reproduction from Jackson & Sutherland’s book. It is all of half a page with scant practical descriptions.

In February 2009 produced a small-scale test boat using fiberglass in place of steel. The test was unsuccessful as the boat was too rigid and cracked into pieces. That March, we began a larger attempt using chicken wire, cement and sand as out-lined in Jackson et al in Malibu, California. This location was chosen because of a loophole in California case law that allows for the use of sand that would otherwise be considered state property above the high tide line on any given day with the permission of beach-front property owners. Otherwise the use of sand constitutes theft of state property, prosecutable under state law. Detailed description of this process can be found under Concrete
