Hi, I am wanting to clarify my frame spacing. I have looked at some models as well as yours and the frames are double at the keel and single at the top timbers. I assume yours is a model plan. I am trying to work from original ship plans, particularly some sketches alongside the plans. If I understood these correctly the frames butt each other at the keel and taper from 12.5” through 8” to 6” at the top rail. Do you know if this is common? Any advice or guidance, greatly appreciated. My build blog seagull has photos about this. Thanks.
