Do you suppose the 939 is a like replacement for the 900SF as far as range and low end goes for 95kg rider?
Nope. Not at all. Funny you mention that because the other day I was on my 939 and a 62L freestyle board and my friend was on a SF900 and a smaller mid-length board. We switched a few times. These foils are very different. the SF900 is much liftier and can get going in lighter winds. The 939 is much faster, but even though is has a bigger span, it has considerably less area and the tips are really narrow. The SF900 can lift with a steeper angle of attack without stalling. The 939 will stall if engaged at that slow speed and sharp angle. The 939 glides much better, but has a higher stall speed. The SF840 might feel closer to the 939 in terms of lift, but the SF has a much lower aspect ratio. IMO, if you have an SF900 and want to try a V2, get a 999.
