Now in its third edition, this book on fibreglass boats has been completely rewritten and updated, and concentrates on explaining the principles of fibreglass construction, as well as sound practice. Although it can be used by amateur or professional boatbuilders alike, it is couched in layman's language, avoiding technical terminology. It explains the peculiar nature of fibreglass, its durability, its weaknesses and defects, the effects of use and latest research into causes of the biggest worry for owners – blistering or osmosis. It is aimed at owners, students, surveyors and boatbuilders, or anyone who wishes to understand the many facets of fibreglass boat construction.
