Thanks Tony. I found a way to actually put in bulkhead as a component in the model. I drew one in on the model. But as I said earlier it was always part of the one of the existing panels even if was on it's own layer. So I selected the four points of the bulkhead and exported/saved it as a PART.

I then undid the changes to the boat. Imported the PART and it placed it where it was originally and as new component. I went to another boat and I could import the PART in there too. I had to resize it and move it but it gave me something to work with. When I develop the panes it ever created the bulkhead.

The downsides for anyone that tries this. The thickness of the hull isn't allowed for and I haven't found a way to make it mate up to the curved deck. Neither of these are a big concern for me.

I just wanted to be able to locate the bulkheads and get some offsets that are close. This allows me to do both.
