The downsides are the number of clamps involved (I've resorted to lashing stringers to the frames with cord when I run out of clamps) and the high-tension bendiness of curved wood. Wrapping the stringers in towels, then pouring boiling water over them and wrapping in plastic for an hour steams the sass out of them.
Well, some of it.
View from the bow. Here you can see the angled notch cut into the forefoot to receive the next stringer -- in this case, #3 on the port side. (I numbered them from the top. Five total.)
You can also get a sense of the sweet knife-edge twist those bottom planks will take as they curve from the sides into the narrow forefoot. Not looking forward to wrestling those into place.
The round hole in the bulkhead will be fitted with a small hatch, so you can reach into the forepeak for light storage (lines, etc.). Had to cut that some weeks ago, as now that the stringers are nearly on, it's hard to reach through the sides of the boat!
