New Britannia

   The new Luna Rossa seems to have gone down the same design routee with an extended longitudinal bustle, albeit not as extreme as Brittania RB2.  I hope Brittania is quick in a straght line as I suspect that it isn't going to be very agile manoevering at sub-foiling speeds.

	my take on its for end plate effect and aero, and also acts as a "moth hull" as in low wetted area compared to the large surface area of the rest of the boat for those touch down moments. of course could be totally wrong.

	I believe the 'bustle' along the bottom is to end-plate the sails when foiling. It looks to me like it is designed with foiling very much in mind and not for floating about. In this game you need to be bold and innovative and it certainly looks like that to me, I hope the gamble pays off (personally I think it will).

	I reckon that the pre-start manoeuvres and slow speed performance will be irrelevant (unless its really light). Once up on the foils it will be a drag race. It looks to me that the Brits will have got it very right or very wrong. It wont take long to find out.

	I think it's more the weird keel line, lumps and bumps which are puzzling people. I take it that the computer and clever people think it helps pop the hull early. I'm afraid the adage "if it looks right" will come back and bite them in the bum...

	Mono Hull, foils on either side lift out of the water, to reduce drag, the foils come together under Hull when going slowly, similar to normal yacht,over simplified, but basically correct.

	Not a clue . One can only assume it’s about helping it get foiling or about aerodynamics when foiling . Hopefully there are clever people on here that can give us the answers Edited by Grumpycat - 19 Oct 20 at 4:46pm

	Anyone got any ideas as to why the latest Britannia is such a strange shape?
