Wooden Mast Partners

[benz]

I made my boot like yours, Allen, only with 2" vinyl pipe wrap tape rather than duct. Being plain black, I didn't need to cover it for looks, and it held up well to two years of tropical sun. And it never leaked a drop. But my boat has the advantage of a small, special-built coaming around the partners, which the boot goes to the outside of, which helps a lot. It would be easy enough to fabricate one with G-10 and epoxy.
