Building Jim Brown's 62' Trimaran Design - Mark Hassall & THAT

Jim Brown - "Let me get this straight: Im going to put a 62' trimaran (deisgn) under a 39' Erickson rig?"

Mark Hassall - "Building a 62` trimaran in primitive jungle conditions, without jack-scratch for materials, except what I could scrounge or create myself, gave me a profound sense of power. "

In 1973, my wife Bonnie and I arrived in the Rio Dulce, Guatemala, after a three-and-half-year sail around the world aboard a Brown Searunner 37 named Talofiafaoe. Jim Brown and I published a book about that trip called Love for Sail...

Sailing - Monohull Vs Multihull
A few weeks ago I had the opportunity to hold an American Sailing Association (ASA) clinic to certify some students for the ASA 114 level which is the Cruising Catamaran level. This advanced cruising standard is for individuals with cruising experience. Successful completion of the clinic qualifies the student to act as skipper and crew of a 30-50 foot multihull sailboat by day in coastal waters. The standard includes those skills unique to a 30-50 foot multihull. For years, although I have sailed on a few catamarans, I was always somewhat leery of them. My motto was always "give me a good sturdy monohull and everything will be okay". I was always concerned about the stresses placed on the two hulls which were separated by several feet. I thought they might twist or otherwise behave poorly and fail. I'm afraid that I am now reconsidering my position. The clinic was held aboard a 40' Manta. Man...what a beauty she was. The cockpit itself could comfortably seat 10 including the helmsperson at a separate station. There were deck chairs anchored just outboard of the cockpit on each pontoon. On the bow, there were more anchored deck chairs and a trampoline area for sunning. Aft of the cockpit was a bank of cooler boxes at least 8 feet wide which could store enough drinks and snacks for more people than you could carry. There was a built in propane grill (all stainless) that I would die for. I'm not sure how many square inches of heated surface there was but I'm sure you could cook steaks and potatoes for 12 or more.
