RS Feva S
The S version is the one used as the early learner version by many sailing schools.The principle difference is not that the same controls aren’t there as with the race version, but that the standard version isn’t as adjustable. Thus once the basics have been mastered it is often sensible to move onto the race pack equipment as learning the more intricate controls is then facilitated.
The S version also uses a smaller (roachless) un-battened mainsail.
