Just to put in my bit on this. I suspect the BR 17 will prove enormously popular and probably will eventually oust the Storm 17. Double-enders are popular for their romantic, Norse-viking connotations, but I think a transom-ender will always prove more popular for general sailing. It gives more cockpit space and storage space. It probably allows an easier tiller/rudder arrangement. You can get in or out over the back without capsizing the boat. (That will always be popular with families and anyone who likes to jump in for a swim, like me.)
Having the choice of rigs and numbers of masts is sort of good, but I suspect that as Claus suggests, you want clearly defined products for marketing. Everyone knows what a Drascombe Lugger is, because they are all built the same. You either love them or hate them. If the BayRaiders have one mast or two, gunter or bermudian or lug sails, it could make it hard to estblish a clear brand.
I think within the next five years the Swallowboats line up will be:
Trouper 12
BayRaiders 15, 17 and 20
SeaRaider
Baycruisers 20 and 23
Storm 15, 17 and 19 as kits on request
Winsome pedal boat (I really want one of those on the Thames!)
What I think is lacking is a really small pram tender kit. I want to build one in the next year or so and would love to build a Swallow Pram, but at the moment the only thing I like is the Eastport Pram
