This masterly work will continue to be an invaluable source of reference for anyone wanting practical advice on working with GRP, in order to make repairs and improvements correctly and thus extend the life of their boat. Since it was first published 45 years ago, Hugo du Plessis' Fibreglass Boats has become a classic, relied upon by owners, surveyors and boat builders keen to understand how fibreglass behaves, and obtain practical advice on working with GRP. In a deliberately non-technical manner, he explains the peculiar nature of fibreglass, its durability, its weaknesses, where its likely to fail, the effects of use and the weather, plus the latest research into causes of the biggest worry for owners - blistering and osmosis. 'One of the most respected works on the subject...thorough and its scope is vast' Yachting Monthly 'A long-established classic' Kelvin Hughes
