There were a couple of interesting comments on a previous post about the engine arrangement in Daisy Grace and I think it is worth looking at in some detail. I think the Swallowboats solution to the problem is one of the best I have seen, and it sold the basic Bayraider design to me.
The Swallowboat Storm series have a curious solution, with the tiller behind the mizzen mast. All users (and the builder) assure me it works perfectly well. I have never tried it but it looks weird to me.
