I asked this question within another bigger thread but didn't receive any response, so thought I would try my luck here!

Does anyone have any thoughts or info on the likely top end speed differences between a wave sail, RAF freerace, and cammed slalom sail in smaller sail sizes??

I have a 5.5 crossover RAF sail that I will keep for waves, but wondering about getting a 5.7 camless freerace sail (hellcat) for more speed on flatwater. Would there be little top end speed difference in smaller sizes/higher wind, or still worth it?

Thank you!

The more stable foil of the Hellcat will let you sail it in stronger wind and be able to use the extra power but in comfortably powered conditions the difference will be small. If you want it for the main purpose of going faster go for a slalom sail, I reckon.

The smaller the sail the less the difference is in the top end, but there is also less difference in the maneuverability as well.
