Doc, just a word of caution. When you scale up plans, there is almost always some deviation from the original print. Something else to be aware of is that you may have to add additional framing or ribs to bridge the larger areas between the ones shown in the original plans. I'm having to redraw, by hand, a set of plans for a boat that I scaled up 20%. While 20% may not seem like a lot, over the length of a model, that resulted in a lot of unsupported skin, going from six frames supporting 24" to six frames supporting 29". I ended up having to add two frames, moving a main cross frame forward and respacing the rest. The bad part is I still have 22" left to go FORWARD of the 29" point that requires respacing and adding more frames to support the main running surfaces
