Glad you like it - coming from you I take that as quite a complement although of course Mr Morrison is the guru on this. I'm glad to hear you are "in step" with the concept
Underwater shape up to the chines should be pretty much the same as Scarlet although it is possible with my mould construction it has varied slightly from the profile. The frames were designed to take 6mm ply but I realised soon after that bending 6mm around the complex curves was never going to work so I used 3mm instead. Result is that it is about 3mm smaller all around resulting in a slightly smaller hull. It measures at the BMS but only just!
I discussed with Phil M the spray rails idea at some length and also looked at photos of Scarlet cutting through the waves and it seems this idea may help to reduce the amount of water thrown vertically in the air which must take energy and increase drag. May also promote lifting of the bows. Also taking note of Bethwaites Performance Sailing book about the sharp chines was an influence reinforced by Bill Beavers tank test article. Whether or not the lifting of the hull rather than slicing through the water as is typical of the canoe is valid will be an interesting test.
The buoyancy thing may be total cobblers but I wondered if when shifting weight back it would sink the transom and help lift the bows higher for planning?
Interested to see this new concept of yours - any piccies?
