New Laser Performance Boat?

Mike - must be a really slow day for you to bite on that one.....am pretty sure I have seen you sail past a phantom upwind and I am fairly sure I have too in my H2 in certain conditions at Burghbados...my point is that an inability to get a boat to go well upwind is probably down to the helm rather than the foil shape :-)

I made that claim first time I bought a Blaze, even went on to make my own foil for it with the chord deep point further forward, which I'm sure we all know, because we've all studied our Naca sections.

Deep chord forward slow speed good upwind (Better range of AoA more early lift), shallow chord further aft better at speed (less drag), with a whole host of compromises in between.(Also one of the reasons I assumed the gybing plate idea on 505s came about, better AoA with a shallow draft foil)

Like I said I haven't studied the section of either compared, but five will get you ten that would be the reason for slow speed lack of upwind performance, it's certainly 'a reason'.

When I did my one off singlehander the first iteration daggerboard, which was a typical Moth/Cherub high speed laminar flow section was a bitch for stalling out at low speed, especially coming out of tacks. Determined to solve that the next board was a much more stall friendly board, which pretty much solved the tacking issues, but it took a considerable sparkle out of the performance at speed. I was surprised by how much difference it made, upwind and down, but most difference crosswind.
