: I am thinking it should be simple to convert it too. Hoping someone had done
: it and would chime in.

My first SOF (first kayak, too) was a Yost-style frame based on a North Alaskan retrieval kayak. I took the long way around to create cross sections, etc; I certainly made it more difficult than it should have been modeling the frame in Rhino instead of FreeShip. Starting with a design in FreeShip will make it quite easy. You are ahead of the curve having built and paddled the design already.

: Then I think about how happy I am with my Wren design too. There are a couple
: of minor appearance items I am not happy with and I could fix in a SOF
: version. I have just never been one to follow the crowd. Plus there is
: something special about your own design.

Yes, there is something special about having designed your own kayak. I've been bitten by that bug too
