Scheherazade is a 154′ 7″ Bruce King-designed ketch under construction at Hodgdon Yachts, in East Boothbay, Maine. Scheherazade is 60% larger than Antonisa, the last Bruce King/Hodgdon Yacht collaboration, and is the largest sailboat under construction in the United States. Continue reading →

Replacing Damaged Balsa Core

By Bruce Niederer — GBI Technical Advisor

Above: Surprisingly, much of the damaged balsa core on TRIPLE THREAT was well bonded to the glass skin, as it was to this section of skin around the chainplate. The bad core that didn’t come out with the glass skin was removed with a chisel.

I love my boat. I love to spend time with it-sailing it, working on it, improving it.

I think I need my head examined. Continue reading →

Protective Skin Creams

Do they interfere with adhesion?

By Tom Pawlak — GBI Technical Advisor

We recently completed adhesion testing for a boatbuilder who was concerned about surfaces being contaminated by workers who use protective skin creams. The builder wanted to be sure that residue from the protective creams did not contaminate objects touched by workers throughout the day. We tested five products: Derma Shield™, Gloves in a Bottle™, Unique Skin™, SBS 46 Protective Cream™, and SBS 40 Medicated Skin Cream™. Continue reading →

My first experience with cabinet scrapers occurred shortly after hiring into Gougeon Brothers. Bill Slaby, a wood/epoxy technician who specialized in mold building, routinely used cabinet scrapers to remove irregularities on cured epoxy coatings. Continue reading →

ARION

Damian McLaughlin Rebuilds ARION

By Kay Harley

Above: ARION as she looked in 2001.

Damian McLaughlin, a custom boatbuilder from North Falmouth, Massachusetts, has been designing, repairing, and building boats for more than thirty years. Recently, he finished the reconstruction of Arion, heralded at its launch in 1951 as “The first auxiliary sailboat built with fiberglass,” and “The largest one-piece hull of reinforced plastic in the world.” In 1950, Sidney Herreshoff, son of the famous Nathaniel, designed the 42′ Arion to be built using what was then an innovative new material: plastic resin reinforced with glass fibers, otherwise known as fiberglass.

Building an Efficient Icebox

Building an Efficient Icebox

by Captain James R. Watson

For maximum enjoyment when cruising on small craft, you need to carry food and beverages and keep them cold for the duration of the trip. While you can purchase good icebox/coolers in many shapes and sizes, these may not quite fit where you want or keep food cold long enough on extended cruises. Building a custom icebox with WEST SYSTEM® epoxy is neither difficult nor expensive.  You can make it exactly the right size and build it in place or make it portable. You can also make it more efficient than a store bought icebox. I’ll show you how I built one to suit my needs, but these construction techniques are easily adaptable to your own requirements.

Chair Repair

With WEST SYSTEM Epoxy

by Brian Knight—GBI Technical Advisor

Above: The chair repair.  Masking tape protects the seat, and the arm is clamped in position while the epoxy cures.

My cousin, Gary, brought me the broken chair shown in the picture below. The spindle and arm assembly was broken off where it attached to the seat of chair. Although the chair was not a priceless antique, it had sentimental value and he wondered if I could do a chair repair. While I was not concerned about the structural aspects of the repair, the cosmetics could be difficult. Fortunately, the spindles were not badly splintered so it was reasonably easy to make the repaired area look good. Continue reading →

fiberglass tub and shower repair

Fiberglass Tub and Shower Repair

By Tom Pawlak

Construction of fiberglass tubs and showers uses methods and materials similar to those for building fiberglass boats. Gelcoat is applied to a mold and allowed to cure. Then chopped fiberglass and polyester resin are applied over the gelcoat and worked into the surface. To create a stiff and strong fiberglass tub or shower enclosure, the laminator uses a grooved roller to compact the fibers against the gelcoat. The quality and strength of the laminate depends on Continue reading →

A Quick Architectural Fix

Wood Trim Repair

by Mike Barker

Last summer I used WEST SYSTEM® Epoxy to repair a small section of rot in a rough sawn cedar trim board on my house. Before gutter was installed, the trim board was wet frequently, but well ventilated. Only a narrow center section of the #2 grade, 1″×12″ board seemed to be vulnerable. Continue reading →
