In the CLC forum on the OC1 posted there, guys from CLC talk about not feeling that they have enough interest to work out a OC1 design so for the most part it's not going to happen.
I have read quite a few articles from Bjorn Thomasson, and looked through his website but I don't see any reference to working on a OC1 hull. As a matter of fact I talked with him online in regards to my Surfski's seat design. He was very helpful to me explained a few a few ideas that in the end gave me the confidence to build a layup seat for the boat
I have thought about adapting a ski design but the OC1 is 14 to 16 inches at the widest point, so I would need to redraw all of the stations to narrow them. I have adjusted length and made stations that were designed to the outer surface offset to the inside of the strips but that isn't the same as taking 15% out of the hull width. The next concern would be working out a design for the Ama and Iako, I have not built these parts in the past and I don't have a boat to study here by my home so making my own design would be my last choice.
