Actually, the gunnels themselves were fine. Or were fine until I over-clamped one end, trying to force it into shape. There must have been a small defect in the oak, because I broke off a corner. Most frustrating.
My goal was still to refit Cabin Boy using wood I had on hand. I'm trying to preserve my limited building budget for the Blue Moon's cabin build. Unfortunately, I didn't have another 10' long piece of oak. This stymied me for awhile, until I realized I could simply scarf back on the 2 foot hunk I'd imprudently cut off a few days ago. A bit of a pain, but I'd get to practice my scarfing skills.
I'd been reading one of the best boatbuilding books I've ever found, Walter Simmons "Lapstrake Boatbuilding". This book has a very useful hint on how to easily find the right angles for a scarf.

Here are those simple lines on my two pieces of oak. I started to cut and then realized I'd forgotten to take a photograph.

Although I complain about epoxy from time to time, there's no doubt epoxy is perfect for scarfing. Some will say epoxy doesn't work on white oak, but if you read the West System manual, you'll find this is not true. You just need to make sure the surfaces are roughed up a bit with sandpaper and, if you are the cautious type, wiped with alcohol.

The next day, I just gave the gunnel a light sanding to remove the excess epoxy. The results were quite alright, I thought.
