Hypersonic 133 DRAM vs formula

[camilo]

Hello:

I've been using a FW board for several years and even racing at a local level. The reason why I use my formula is because in my spot wind is not very frequent... I do not race any more. I'm using an 11m sail as my unique rigg.

I'd like to change my board and maybe take a smaller rig (not sure of this yet) and try an Hypersonic, but I'm afraid to loose many windsurfing days... I know there's a difference between the ability to start planning between Hypersonic and a regular formula board. I just need to know how big is that difference.

My question is, if we were to use the same rigg and just change the board, how many knots later would I start to plane on a Hypersonic as compaired to a formula board? I know my question might be difficult to answer, but I think there night be a concrete answer or maybe a range.

Second question is, the sail range for that board goes to 10.4, is that sail area efficient for that board?

Thanks!

Camilo
