View Full Version : Fins/Sails S-Type 93
22nd July 2007, 09:40 AM
I have just bought an ST93 and looking at getting a 6.0m multicam performance race sail and a 5.0 high wind sail.
I am looking at Tushinghams: 5.0 Storm and 5.8 X15, but also considering Loft, KA, Severne. Any recommendations.
What fins would be best for these sail sizes - the supplied Drake fin is a 34 and from what I have read I should probably get better performance fins to suit each sail.
I am 78kg and sail in Perth West Australia where sailing on this board will be in 18-25 knots on choppy flatish estuary and also ocean.

You're on the right track taking a more cammed sail for the larger (ST93) sail sizes and then complimenting the rough water speed aspect of the 93 with more "control" sails in higher wind /rougher water.
Expect the ST93 will sweetspot around 5.8m, but you may (or not) prefer a slightly free/er sail in that size, rather than a fully locked racesail (X15) for Perth 5.8 conditions.
Unless you're a fully dedicated, no compromise boy racer, you might find a higher s/miles per hour ratio on a good (draft stable) fast freeride sail (few cams, or even nocam like Severne NCX 6.0) in the larger sail range as well. I've also had really good ST 93 results using Severne S2 (fast freemove) in both 5.8m and 6.4m(about the upper practical limit for my weight on 93)
Stock 34 fin will be OK for around 6m conditions, fully powered 6m something around 30-32cm will also double as good choice for higher winds (technical catch here is that these sizes relate to fins of similar aspect ratio to the stock one (moderately hi) : ST93 can be tuned very nicely - especially for rougher conditions- on lower aspect ratio fins as well, which yields a lower "size" (depth) , but a similar performance size recommendation....That's to say, a moderate lo A/R 28-29 would be same perf size as a higher A/R 32 (make sense?) . All of which means you got a lot of choice and range in the fin side of things.

Excellent, Thanks Ian.
I will go for a slightly less full on sail in the 5.8/6.0 size. I am getting back into the sport after 5 years out and this makes sense - will look at a racier sail next year when no doubt I'll get the GPS speedsailing bite seriously.
Thanks also for the information on fin sizes - I'll get something around 30cm, similiar aspect ratio, so I can compare and work out the best transitions between the pair.
