Coaming Boxes

Summary
(please click on any of the pictures for a larger one - use the BACK button to come back)

I have always wanted coaming boxes. None of my previous boats had coaming boxes. The Nimble has the MOTHER of all coamings. I was going to have coaming boxes.

As is the case with every project I ever start, there is always something that makes it not quite so easy.

The only place that I could put the coaming boxes had a curve running lengthwise of the box. It was to much curve for my usual tried-and-true Starboard shim approach.

I had to find another way.....

I started by cutting a couple of 1 by 2 boards to match the curve of the coaming where they would be installed.

Then I glued and nailed some 1/4 inch plywood over them, and VOILA a form is born!

I put clamps and wood rails along the flanges of the box and tightened them down snug.

Then (drum roll please.....) I used my Harbor Freight-special heat gun and heated the whole back of the box while alternately tightening down the clamps until the flange was curved to match the form.

It worked!

Prior to installing them, I routed off a piece of starboard and screwed and bedded it to the front edge as a fiddle

Lessons Learned

Springback is called that for a reason (and I should have known it, too!).
