Creating Nonskid Surfaces

By Greg Bull – GBI Technical Advisor

Nonskid surfaces may need to be replaced because they are worn down from years of use, or were removed during a deck repair. If you want to match an existing pattern, flexible molds are available for matching a production boat non-skid pattern or for use if a molded appearance is desired. Molded non-skid surfaces are often very open making them easier to clean and they have a more finished appearance (See Epoxyworks 22, “Repair Non-Skid and get Professional Results”).  For applications where it is not practical to use molds, or a simple and functional non-skid surface is desired, there are some easy options.

Using a Quick Mold

I used this quick mold method in order to move the mainsail traveler cleat from the transom of Strings to put it within easy reach of the helmsmen. The part I made had to be strong enough to withstand the loads of the traveler.

A male mold was the best choice for creating the shape to put the cleat where I wanted it. I
began with Owens Corning® Foamular® 150 foam insulation, the “Pink Panther” rigid board foam sold at home improvement stores. It comes in different thicknesses and will bond easily with WEST SYSTEM Epoxy to build thickness or create the desired shape. This foam is inexpensive and easily contoured with basic hand tools. I used a piece that was 2″ thick by 3″ wide and 7″ long. Continue reading

The work of the Gougeon brothers has been like a guiding light to me starting when I was a young teenager. It wasn’t just the methods and skills they developed that inspired me (and led to my career in boatbuilding), it was the “outside the box” thinking about boat design they employed. While Meade Gougeon led the effort to develop and teach epoxy skills and building methods, it was his brother Jan who had the courage to design, build, develop, and race boats that were very unusual and often counter-intuitive, yet very successful. Jan’s G-32 catamaran is an example of his genius. Continue reading

Carbon Skinning

Why reinforce with carbon fiber?

By Don Gutzmer

Carbon fiber has very high strength-to-weight ratios and higher stiffness compared to many other reinforcing fabrics. These special properties make it ideal for applications in aerospace, automotive, military, and even sporting goods. When combined with a WEST SYSTEM Epoxy it can be used to build high-end composite parts.

Skiff Details

By Captain James R. Watson

A skiff is a shallow, open boat with a sharp bow and square stern. After building some skiffs of various designs and having the opportunity to observe them over time, I have found details that have worked nicely that might be a value to others. Continue reading

Strings Centerboard Adjustment

By Greg Bull

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 locking them straight. The center boards 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 boards to jibe. Continue reading

Soundproofing a Generator

By Ted Wasserman

For soundproofing a generator, I built an enclosure with 2 lb lead sheet sandwiched between 24 oz double-biased stitched mat using WEST SYSTEM® Epoxy. The thickness of the enclosure is 1/16” and has a mass of approximately 2 lb per square foot. Continue reading

Harken Flexible Furler Repair

By Tami Shelton

I have a now-discontinued Harken furler unit for my F-27GS trailerable trimaran. This furler is made of an extruded PVC foil with a braided stainless internal liner, with a rod that passes through as the actual forestay. I really like this flexible foil because of its ease of use when raising the mast as well as the fact that it can be somewhat coiled and stowed in the boat for travel. Continue reading

Of Applecores and Deadeyes

By Bruce Niederer and Bill Bertelsen

Gougeon Brothers, Inc. has supported our local tallships—Appledore IV and Appledore V—since they arrived at their downtown Bay City facilities on the Saginaw River. These steel-hulled, gaff-rigged schooners are typical of the type that sailed the Great Lakes and coastal waters right up to the end of the age of sail. Schooners were the primary means of transporting goods and people over long distances. Continue reading
