Strings Centerboard Adjustment

By Greg Bull — GBI Technical Advisor

Strings, as unique as the man who designed it, continues to be a work in progress for us at GBI. In Jan Gougeon’s first year of sailing Strings, he noticed the boat felt sticky at times. He thought it might be the centerboards jibing too much and the solution might be an adjustment to lock them straight. The centerboards work as jibing boards by having two high spots on each side of a centerboard head creating the pivot point to get the boards to change angle, or jibe. The actual pressure from the boat going through the water and wanting to slide sideways gets the centerboards to jibe. Continue reading →

Fairing the Bottom of Adagio

By Greg Bull — GBI Technical Advisor

While fairing the bottom of your boat may seem beyond your reach, it is a project that novices and experienced boaters alike can accomplish with a few simple tools and a love of a little manual labor. Most seasoned sailors would agree that a clean bottom leads to faster sailing. Sometimes it may be necessary to do more than scrub away the algae and zebra mussels, though. In the case of Adagio, 44 years of sailing was starting to ripple the bottom of the boat. Simply put, it was time to fair the bottom. Continue reading →

Building the Dream

By Laura and Philip Harvey

We started building our dream boat, a DH550 55′ catamaran we christened Wild Vanilla. Our catamaran was built on a piece of land just behind Budget Marine in Trinidad, during a break in our long-term family cruise. Before we began, we had sold our boat building company, Harvey yachts in Cape Town South Africa, and set off on our 38-foot cruising cat. Onboard were our nine-month-old son and our cat, Velcro.

Restoring a Gougeon Tornado Catamaran

By Andy Davidson

I have just about finished restoring a Gougeon Tornado catamaran. I’ve always had and loved catamarans, and this one had been sitting out in the sun at the Oklahoma City Boat Club for years. Bob, a fellow club member, offered some parts. His plans were to “chainsaw the hulls tomorrow” and put the pieces in the club Dumpster. That was the push I needed. In a moment of insanity, I told him there was no way I could let him do that. Continue reading →

Foam Strip Plank Boatbuilding

BY JOHN LINDAHL

A couple of years ago my son Ian asked me about building an A Class catamaran. Having built several of these in the past and knowing what was now on the market, I came up with a build method that would:

Allow us to build a competitive design.
Be at or under the class minimum weight of 165 lb.
Be as strong and stiff as anything on the market.
Be competitive in quality and price, but not get trapped in exotic equipment expense. This meant no vacuum bag, no pre-preg, no resin infusion, and no autoclave.

Jan Gougeon Launches STRINGS

By Grace Ombry

Cover Photo: On July 9, 2011, the 40′ catamaran STRINGS was launched at the Gougeon Brothers boat shop on the Saginaw River in Bay City, Michigan.

Jan Gougeon’s monumental launch of STRINGS occurred in July of 2011, over a decade after the birth of the project. Jan passed away on December 18, 2012. We miss him. —ED

In Epoxyworks 17, we published a photo with the following caption: In the recess of the Gougeon boat shop loft, something unusual is taking shape out of plywood, foam, carbon fiber, and epoxy. There is a minimum of plans and drawings. It evolves, piece by piece, mostly from its creator’s head. It’s not a trimaran. Not exactly a catamaran. Technical you probably wouldn’t call this a hull. It’s more of a fuselage. (There is an aircraft canopy involved.) For now, let’s call it Project J. We’ll keep an eye on this project in coming issues and see what develops. Continue reading →

Project X Fairing Technique

By John M. Thomas

Jan Gougeon’s newest boat, currently called Project X (later christened STRINGS —Ed), is in the home stretch to completion, and Jan is addressing the fine tweaks of coaming and fairing by using a special fairing technique. Continue reading →

How WEST SYSTEM® Products Got Their Start

2009 was the 40th Anniversary of Gougeon Brothers, Inc. 1969 marked a point in the Gougeon brothers’ careers when they applied all they had learned about wooden structures and epoxy technology to manufacture, for the first time, a product utilizing wood/epoxy composite construction. The full story of Gougeon Brothers, Inc. begins long before that date and is sure to continue well into the next 40 years.

A Quick Fix to a Broken Spinnaker Pole

By Meade Gougeon — GBI Founder

Above: Meade fixes his broken spinnaker pole with a blend of WEST SYSTEM 105 Epoxy and fast curing G/5 Five-Minute Adhesive.

Adagio, our 35′ trimaran, was already off to a bad start in the 100th anniversary of the first running of the Chicago to Mackinaw race with an over-early call by the race committee. Everything went downhill from there when we had to deal with a broken spinnaker pole. Continue reading →

James Wharram Designs

by Captain James R. Watson—GBI Technical Advisor

For many decades Gougeon Brothers Inc. has kept in contact with multihull designer James Wharram. Wharram, of Cornwall, UK, has sailed and designed Polynesian-style catamarans for 50 years. Amateurs and professionals have built his boats and sailed them to all corners of the planet. The designs he creates with his engineer and artist partner Hanneke Boon have evolved over the years, but remain unmistakably, Wharram Catamarans. Continue reading →
