October: Building a Cold-Molded Custom Designed 20 Foot Catboat

October 2013: The Dynel Process

The house gets a layer of 1/2" plywood which in turns gets puttied, sanded and re-puttied as needed. The companionway opening is cut. Seth has cut some hatch slide dummies to get a sense of things. In the meantime, working off the boat, he's built the centerboard (1" PVC) and installed it. The lifting mechanism needed to be designed around the hanging locker next to the centerboard trunk. All in a day's work.

Dynel is a very fine weave material that runs and snags if there's anything to catch it, making a mess of the cloth pattern we're hoping to maintain. The fabric mimics traditional canvas. Because it's wetted out in epoxy, it really adds an additional layer of protection against abrasion. at the risk of repeating myself, it's all in the preparation.
