To consistently achieve speeds in excess of 30kts you need to
1. bear off the wind to angles approaching 140 degrees and
2. sail in overpowered conditions
No-cam (RAF) sails loose too much power in these sailing angles and are too much of a handful when overpowered going to windward back to the top of the speed run. 4 and 3 cam race and freerace sails with adjustable outhauls are the go. EG KA Race (4 cam) and KA Concept (3 cam), Severne Reflex (4 cam) and Severne Overdrive (3 cam).
What??? It's 30 knots not 40. I can consistently sit on 30 all day on big waveboards with wavesails, no adjustable outhaul, single straps & wave fins in the chop on the right angles. Look at Simon F & Peter in BCB who consistently see 35 knots in open water on no cam noa's or ncx's, gybe with ease then kick a$$ back upwind of all but a few.
It's all about balance of the entire setup not just the sail, Im not lacking drive or stability going upwind on wavesail. I wash off chunks of speed due to wave fin that is inefficient at that aoa, soft rails & super wide stance that lets alot of wetted area on tighter angles. The extra drag can create instability especially if dont get rig entirely right but the no cams arent too bad, much better than used to be- I cant remember the last time I got backwinded but 20 years ago would easy see that on no-3 cam sails.
If you match like gear ie nice no cam sail with freerace fin with performance freeride board most wont even come close to the speed potential of that setup, they might get 90% of it which imo is better than not getting a full slalom board/sail out of first gear. The first step in getting that performance is rigging the right size sail for the conditions, once wind hits 18 knots i am consistently on 0.8-1.6m smaller no cam vs race sail- smaller sail less drag, better tension, power directed in right place, much easier to use. If you use 7m no cam in 25 knots cause all the race sail guys are using 7's then yes you are going to suffer & see all those bad things they say.
So dont just look at sail it's the whole setup, fast people are fast no matter the kit or conditions because they are good at getting the balance right, the top 5% of sailors will notice the actual speed difference in gear & see eachothers speed change if something is or isnt working. Not being rude but if it's 18+ knots, not overly choppy & you are struggling to see 30 knots out of your full on slalom kit then you are making your sailing hard & on the wrong kit. It's good practice & you learn in trying to match the pace of guys on full slalom kit on not full on kit.
