The Must-Know information about catamarans, trimarans & proas for every multihull owner or prospective buyer. This includes buying information and understanding the most important areas of boat maintenance for your vessel. Multihull expert John Marples gives you all the essential information, which covers sailing yachts, luxury boats, cabin cruisers, new boats, used boats, boats for sale and small boat designs. Multihull owners can protect their investment, or save themselves a lot of grief, when it comes to these unique craft, including: -- Critical areas of multihull service and performance -- Common self-built and production boat problems -- Understanding the "multihull platform" and its effects upon sailing and performance -- Main stress points and how to increase the longevity of your boat -- Design flaws and danger signs in catamarans and trimarans -- #1 multihull mistake (dangerous and decreases sailing performance) -- Weight distribution for safe sailing and increase performance -- Multihull ballast issues and performance -- Fundamental difference between monohull and multihull rigging -- How to easily perform routine maintenance on cruising multihulls -- Main areas for multihull maintenance (what are they ... and why?) -- Easiest (yet most neglected) multihull maintenance issue -- Why fiberglass production boats and wooden boats can both suffer from mildew and rot -- What to change put in the hulls each and every time you go sailing -- Active (and passive) pieces of equipment to help keep your boat fresh for years to come -- Must-have pieces of equipment to include in the engine area -- Avoiding chainplate errors (that cause corrosion & structural damage -- #1 way small multihulls suffer from damage"

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 and trimarans and the skills needed to understand and enjoy them to their utmost. Both racing and cruising yachts are catered for, as are trailer-able multihulls. Seamanship is not a black and white skill. It is an evolution of knowledge; a building of information through experiment, thought and 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 and others sharing their knowledge. It should be on the book shelf of every catamaran and 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 and this second edition is fully updated. It is illustrated with delightful line drawings by Nigel Allison.

High speed catamaran and multihull high speed marine vessel have become very popular in the last two decades. The catamaran has become the vessel of choice for the majority of high speed ferry operators worldwide. There have been significant advances in structural materials, and structural design has been combined with higher power density and fuel efficient engines to deliver ferries of increasing size. The multihull has proven itself to be a suitable configuration for active power projection across oceans as well as for coastal patrol and protection, operating at high speedd for insertion or retrieval with a low energy capability. At present there is no easily accessible material covering the combination of hydrodynamics, aerodynamics, and design issues including structures, powering and propulsion for these vehicles. Coverage in High Speed Catamarans and Multihulls includes an introduction to the history, evolution, and development of catamarans, followed by a theoretical calculation of wave resistance in shallow and deep water, as well as the drag components of the multihull. A discussion of vessel concept design describing design characteristics, empirical regression for determination of principal dimensions in preliminary design, general arrangement, and methods is also included. The book concludes with a discussion of experimental future vehicles currently in development including the small waterplane twin hull vessels, wave piercing catamarans, planing catamarans, tunnel planing catamarans and other multihull vessels.

Robin G. Coles interviews James Brown about Multihulls; catamarans, trimarans, and proas. This was a two hour interview and chock-full of great stories.To learn more read about these top tips included:1. The real difference between multihulls and monohulls is people 2. One disadvantage is limited load carrying capacity. 3. A trimaran has one large central hull and two smaller outer or outrigger hulls. 4. A catamaran doesn't have a bow. 5. A catamaran's widely spaced hulls can straddle a wave crest. A trimaran's float, or outer hull, is not as far from the main hull as the two catamaran hulls are from each other, so there's less room to straddle in a trimaran. 6. The catamaran has to drag its two hulls through the tack. A trimaran, properly designed, only has to drag one hull through the tack. 7. Trimarans are better upwind--they communicate with the pilot in a more direct manner. 8. Trimarans are safer than catamarans.9. Proa has one main hull and only one smaller outrigger hull on one side of the boat, usually to windward.10. Hydrofoils are racing trimarans fitted with J, T, and/or ladder foils; hydrofoils are underwater wings that accomplish the same thing in water that airplane wings do in air.
