Rio Vs Start

[NickD]

Hi Roger

I am just returning to the sport a little larger than the last time I went for a sail (110kg/240ilbs). I've been using some elses kit and get up on the plane but not yet in the footstraps. I'm just about to buy a board and wondered if I should get a Rio or a Start? I need a centreboard as I have to often beat out of the river where I live before I can get going.

2nd question if I may. Is there a spreadsheet that shows sail size for wieght and windspeed as I seem to always be going out with the wrong sail up?

Thanks

Nick
