Coping With The Coaming

Plastic sheeting separates the laminations from the deck

The coaming is assembled from layers of plywood, laminated together. Reading the manual and picturing the assembly I could see this was going to be one of the more challenging tasks in building these boats. I again referred to Laszlo's wood duck blog, and the technique he illustrated for assembling and installing a laminated cockpit rim seemed much easier.
Laszlo recommends putting plastic sheeting on the deck around the cockpit opening and using the boat as a jig to glue up the pieces of the coaming. The pieces will form to the proper shape to mate to the deck, but the plastic stops them from adhering to the boat. Once the epoxy cures, the whole coaming assembly can be removed, allowing easy access to all sides for sanding and shaping.  Once all the rough (very rough) edges have been smoothed the coaming can be epoxied in place on the deck. When I used this method I only had to be concerned with cleaning up the squeezed out epoxy from one glue joint, not several.

The inside rim of the cockpit rim is easily sanded

Once shaped the rim is epoxied to the deck

Very little squeezed out epoxy to deal with using this method
