I've been contemplating a very long, very fast S&G double and can't seem to find what I'm after out there in the realm of stock designs. I think I'd like to go S&G, mostly because she's likely to get used hard and I'd have a hard time doing that to a stripper, but also to get it in the water much sooner.

What I'm after is about 23' (maybe a bit more but I'm limited by my available storage space and would like to keep it within 3 sheets of plywood), narrow beam, and multi-chine (for low wetted surface). Perhaps a CLC West River 180 stretched with two holes? Would the panel offsets for an existing S&G design work if spread to achieve the length I'm after? If I went to woodstrip, could I take the Guillemot fast double and reduce the station spacing a hair to get down to the length I want? Has anybody seen a design that fits these loose requirements. Any other suggestions?

Would it be reasonable for somebody to produce a custom S&G design for me?

Thanks in advance,
Porter
