The Boat Data Book is a treasure trove of invaluable technical information for builders, designers, surveyors, owners and anyone maintaining their own boat. This sixth edition contains more tables of lengths, widths, weights and strengths as well as new data on a vast range of equipment from anchors to masts, propellers to gas cylinders, cleat sizes to winch bases, and hatches to bolts, bearings, cabling and piping. This is the essential reference for anyone wanting to know the breaking strength of stainless steel rigging wire, the correct height for a galley top, the recommended size for seacocks, or what length a mooring rope should be. A must-have reference for owners and professionals. PB 224pp.
