This is an A-Z of seamanship skills for multihull sailors. There are many textbooks on the market which detail general seamanship principles. This is not one of them. Multihull Seamanship is about sea-going catamarans & trimarans & the skills needed to understand & enjoy them to their utmost. Both racing & cruising yachts are catered for, as are trailer-able multihulls. Seamanship is not a black & white skill. It is an evolution of knowledge; a building of information through experiment, thought & experience. There is no definitive word on an evolving skill. Multihull Seamanship started as Dr Gavin Le Sueur’s personal index of ‘how-to’s. It has grown through experience & others sharing their knowledge. It should be on the bookshelf of every catamaran & trimaran. This book is for people who are already multihull sailors, or for those who are contemplating multihull sailing. It has served this community for over 20 years & this second edition is fully updated. It is illustrated with delightful line drawings by Nigel Allison.
