: Hi myrl,

: i conjecture that hybrid yaks are the most difficult of all yaks to keep
: aligned during the bldg process. It would be so easy to distort as each
: successive strip puts its differential bending into play. you don’t have
: predefined deck edges(and therefore sheer curvature) like in a total s&g.

: So the use of temporary or fixed sheer clamps(for consistent sheer curvature)
: and some process of readily alignable exterior or interior formsets(for
: c/l and vertical offsets) might be of use, as well as the winding sticks.
: At the very least, the winding sticks could be c/l aligned.

Oh yes,

I did check the alignment last night, I'm off by about 1/2 - 3/4 of an inch at the stern. I think I can live with that.

I did put a shear line strip down first when I was planking, but I only stapled it to the forms. Of course the staples have pulled off many times since then. So I'd recomment to anyone working the same boat that you afix it better some how (screw?). Also ensure the forms can not move up off the hull, as they can in my setup, just taping them down would have been a big improvement. This should produce the defined shear line.

When I do another hybrid I'll also try and fix the hull in position with ridgid kayak cradle. Likely I'll do a different hull as well, on for expedition, and perhaps multi-chined. we will see.

I think a better choice for a hybrid would be one with a hull that comes up to a higher shearline, taller hull side panels that is. Making the shear clamp (is that the correct term?) method of joining the way to go. This of course is just my opinion, based on experince getting to the point in the pictures on one whole kayak.
