By Ian Nicolson. Boat designers, builders, surveyors and anyone interested in repairing, refitting, and maintaining powerboats and sailboats, have long used the Boat Data Book as the standard reference work covering the materials and equipment used for boats. The book covers boat equipment, materials, fasteners, spars and rigging, engines and powering, and designing for human comfort. There are also 23 conversion tables for everything from weights to wire gauges to thread sizes. When you need to know the breaking strength of stainless-steel rigging wire, the proper height of a galley top, the recommended size for seacocks, or the correct length of a mooring line, the Boat Data Book has all the answers. It belongs in the bookshelf of every vessel afloat!
