Here is another possibility depending on how you/FreeShip deal with panel thickness. When I design a kayak I assume the designed shape represents the outer surface. To turn that into reality I fair the edges at angles produced by my software. Besides making the panels correspond with the outer surface, fairing also provides strength but that is a different story. In view of that, I also correct my stations by cutting 4 mm inside the shapes as computed by my software. I just eyeball that.

Could this be the cause of your station mismatch? Do you fair the panels and correct for panel thickness, or does FreeShip do it for you?

: First off, this photo is not of the finished ready to fillet hull. I
: appreciate the input but I am smarter than that. "WINK" This was
: one taken earlier in the process. Well before I had all hull straighted
: out. The rear one is just laying there!

: The bow bulkhead still looks similar to this though. When I lay out the
: bulkhead and install it it just isn't the same size as the boat. I have
: made three for the front. They all fit similar. The upper panels fit very
: close. The bottom panels appear to be wider than designed. I may have made
: a mistake laying out the bulkheads but if I did I made the same mistake on
: all of them. So I doubt it. Besides I worked with coordinate systems for
: 20 years. Since I have a similar situation at the rear I have to assume
: that the developed panels from Freeship are not exactly right. They seem
: to be a bit wider.

: Checking the boat everything seems OK. Rocker looks good, the shape looks
: like I designed. It probably has a bit more V in the bottom at the bow and
: stern than I designed it with. I though I would take some measurements
: from the chines to see if that is the case tonight.

: If it does the only option is to try to manually correct those bottom panels
: and I don't have a good reference point to work with. So if it just ended
: up with more V as I suspect, I will just leave it alone.
