Reflecting on Sailing Days Past

Cover Photo: One of LADY B’s first sails on the Saginaw River near the Gougeon Brothers boat shop.

Lady B is a sailing sharpie I launched on August 20, 2009. On one of the first sails, I asked Jan Gougeon to come along with me to see what he thought of her. That sail brought back many memorable sailing moments that Jan and I have shared over our lifetimes.

Project X Fairing Technique

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

Making Custom Wastebaskets

By Tom Pawlak — Retired GBI Technical Advisor

Photo above: The finished custom wastebasket fits perfectly in the drawer.

I don’t know about you, but I have problems finding wastebaskets that fit the spaces I have in mind. The baskets are either way too small or a bit too large for the opening. It happened at a previous house we lived in and it happened again in our current home. My solution was to make my own custom wastebaskets with 4 to 6mm (3 16″ to 1 4″ thick) plywood sealed with and glued together with WEST SYSTEM® Epoxy. Continue reading

From Serendipity to Bufflehead

Sailing Canoes

By Hugh Horton

The cover of Epoxyworks 16 shows Serendipity, the sailing canoe I built for Meade Gougeon on a Bell “Starfire” hull after he had seen me sailing my Starfire-based Puffin in the summer of 1998. The Starfire hull was designed by Dave Yost. Continue reading

Make Your Own Soft Eye Pads

By Tom Pawlak — GBI Technical Advisor

If you look closely at some of the photos in the Bufflehead article, you will notice small eye pads  (also called pad eyes) in strategic locations inside and outside of Hugh Horton’s Bufflehead. Hugh makes this lightweight carbon fiber or Twaron™ reinforced nylon line eye pads for his sailing canoes.

He glues them onto the decks or inside his sailing canoes—wherever they’re needed to hold supplies in place or hold flotation inside the hull. The eye pads are easy to make and amazingly strong. Continue reading

Using Google SketchUp to Design a New Cooler

By Jeff Wright — Vice President of Technical Services

Above: Captain and first mate contemplate ways to free up the swim platform and keep the drinks cold aboard the 1986 242 LS, FUNKTIONAL.

My personal boat is a 1986 Formula 242 LS. With a soft riding deep V hull, good performance, and a small but well-appointed cuddy cabin, it is a great boat for me, my wife, and our dog to use for a whole weekend. One shortcoming, besides not having standing headroom in the cabin, is the built-in cooler located in the cuddy cabin. The cooler had a side door and was styled to look like a refrigerator. This may have looked “cool” in the mid-1980s but was impractical. We couldn’t put ice in the cooler without having the water leak out through the door. For any trip longer than one night, I had to use a standard cooler strapped to the swim platform. This was inconvenient and limited the use of the platform at the beach. Continue reading

Fast Blister Repair with Six10

By Tom Pawlak — GBI Technical Advisor

This fast blister repair method is tailored to fixing individual gel coat blisters prior to bottom painting. The advantage of this method is it can repair blisters on hulls recently pulled from the water or hulls that have been out for some time.

Fast Blister Repair Method

  1. Open the Blisters

    Open blisters with a small abrasive tool like 3M’s Rolock™.  2″ diameter sanding disk with 60-grit sandpaper. Make sure you have removed the entire blister, including the edges of the blister dome.open the blisters

  2. Clean the Cavity

    Wipe the cavity clean with an alcohol prep pad or paper towels that have been soaked in isopropyl alcohol. Be generous with the alcohol and change towels frequently so the contaminants are removed rather than spread. Repeat the alcohol wipe process and allow the laminate to dry to the touch. It is particularly important to repeat the alcohol wipe on blisters that were fluid-filled at the time they were ground away.Wipe the blister cavity clean with an alcohol prep pad.

  3. Fill with Six10

    Fill the cavities with Six10 Thickened Epoxy Adhesive dispensed through the static mixing wand.Fill the cavity with Six10

  4. Spread the Six10

    Spread the Six10 Adhesive flush with the surrounding hull with a wide putty knife or plastic spreader. Avoid overfilling the cavities because Six10 is difficult to sand.Spread the Six10 Adhesive flush with the surrounding hull with a wide putty knife or plastic spreader. 

  5. Wet Sand

    Wet sand with 80–120-grit wet/dry sandpaper or wash with water (no soap, no ammonia) and sand dull with 100-grit sandpaper. If you are using Six10 in warm conditions, you should be able to wet sand and bottom paint later the same day. If working in cooler temperatures, allow the epoxy to cure overnight before sanding. wet sand the blister repair area

  6. Paint

    The final step is applying your choice of bottom paint to complete this fast blister repair job.Alkyd finish topcoat

Why this Fast Blister Repair Method Works

Six10 Adhesive is epoxy thickened with fumed silica, which allows the epoxy to remain an excellent moisture barrier. When the static mixer is used to dispense it the blister cavity&nbspis filled with air-free epoxy. This is important because small bubbles in coatings and putties degrade moisture barrier potential by creating shortcuts for moisture to permeate the hull. In the end, Six10 produces a moisture barrier that is better than the original gelcoat.

In our Gelcoat Blister manual, we recommend filling and fairing extensively blistered hulls with WEST SYSTEM® Epoxy thickened with one of our low-density fillers (407 Low Density or 410 Microlight®). The hollow microscopic spheres used to make low-density fillers easy to sand, make them poor moisture barriers. So, the blister manual requires that an effective epoxy barrier coat be applied over the filled and faired surface.

Six10 Adhesive is an excellent option for filling ground-out blister cavities—especially if you don’t plan to barrier coat your hull.

More Good Reasons for Using Six10

Six10 is simple to use. No stirring is required when the epoxy is dispensed through the static mixer. The Six10 cartridge fits any standard caulking gun and always dispenses epoxy at the perfect mix ratio. Six10 makes filling blisters easy and efficient. This is comforting to know whether you’re doing the job yourself or paying someone else to do it.

Students of the Northwest School of Wooden Boat Building in Port Townsend, Washington, recently built the Caledonia Yawl, an Ian Oughtred design. The boat was commissioned by the Four Winds Camp on Orcas Island in Puget Sound and is the second one the school has built for them. Instructor Bruce Batchely believes this is the best built boat to come out of the shop so far. They modified the boat to suit the camp’s need for buoyancy and storage and made the spars hollow to keep the rig light. Continue reading

Bicycle Frame Repair vs Wall Art

The Difference Between a Carbon Fiber Bike Frame Repair and Wall Art

by Randy Zajac

I will start by saying that, in my opinion, most carbon fiber bicycle frames that have sustained damage from an impact should not be repaired—there are too many damaged fibers that are typically unseen. The two repaired frames featured in this article had damage caused by operator error, not impact. The last two bicycle frames are prime examples of parts that should not be repaired for safety reasons. Continue reading
