I have a couple questions about the table of offsets for a 1956 17' Sportsman.
1. Heights from Rabbet - where exactly is the Rabbet measurement? I assume somewhere on the keel.
2.Buttock-15" - I assumed this is 15" from the keel centerline, but the measurements don't seem to jive with the existing frames.
3. Frame Symmetry - the existing frames do not appear to be symmetric side to side. I think they should be. The problem I have is knowing which side is right. If I can figure out the Buttock height, I should be able to determine the correct frame shape.
Any help with this would be very helpful.
Framing, planking and fairing. Repair, or reconstruction. If it's hull related, you'll find it here.
