Lapstrake Boatbuilding has become a classic since it first appeared in the 70s. Initially two volumes, it was combined, updated, and expanded into 400+ pages of background information for American lapstrake practice. Found these days in shops and boat schools across the USA and in Europe. You can learn through trial and error, or make better use of your time and  avail yourself of Walter Simmons' 50+ years of boatbuilding experience.
