My gunwales are mahogany, equal square section inner and outer.

Boat has small decks at the ends.

Planning on tapered ends, down to about 1/4 or less of width, height the same because they're glued on already per plans and instrument. Start of taper just before getting to the decks. I'll taper to 50% of width, then look and feel, keep going as eye suggest works.

The issue is the cross section in the main run of the hull. The plans show simple rounding with a router bit, which looks horrible to me. I was going to lay out like a 1/2 spar, 7/14/7 and plane. But then thinking that leaves a top run that is totally flat.

So I'm considering doming gunwales just a little, like the top of a stair handrail, then laying out the rounding. Anyone do this?

Other standard methods?

Thanks!
