An old shipwright told me .when he started hi apprentiship.when constructing.dingys up to 12 ft Theyhad a system where they could turn the whole boat moulds keel everything held ridged that could be turned 360 degrees thus making a faster construction and ease of construction It was much like a roasting spit Where you could lock it in any position
Why the forms are cut so rough with curves approximated by line segments (so they rather look like polygons). Wasn't the purpose of drafting to give the nice curves? I understand that planks tend to fair themselves when not forced excessively into the forms, but what was the reason not to cut a clean curve on a bandsaw? Is it because of clinker technique itself? I do not have a clinker boat construction experience but finishing a cedar strip-built kayak and I tried to make forms cut and sanded as close to the pencil line as possible. Great series on the boatbuilding trade! Thanks!
You were correct to fair exactly to the line with your cedar strip kayak. With clinker planking the line is of vital importance just on the point where the outer plank edge lands so as long as you plane down to that point for each plank what happens between the plank edges is irrelevant.
Thanks for showing both options for jigging up the moulds and center line. That is very helpful.

Sounds handy. As long as the rotisery has absolute positive stops at 0° and 180°.
