Hey guys, thanks for all the info. I really appreciate it. Ady, just out of curiosity, what effect does the looser leech of the Sailworks Retro have on the sail's handling? You said the brand of sail is less important, so I presume the different cuts of Gaastra, Ezzy, and Sailworks sails are not a deal breaker, but I'm just curious. Also do you use Sailworks masts (such as the recommended Joystick) with your Retros? Thanks, again for all the advice
Devin, I have my own theory about this whole leach thing, but I cant guarantee how much of it is accurate if any at all, so consume at your own risk. Here it goes: the head and the leach of the sail act a lot like an overflow valve . By downhauling to a certain level you are basicaly setting up the valve to reliese a specific amount of extra wind power created by gusts or when hitting chop with the purpose of minimizing the "jerking" of the sail without depowering it too much. The sail designers have a slightly different ways of achieving that and I'm glad I have the pictures of the sails that represent three diferent ways of solving the problem- the soft, the hard and the medium.
The Ezzy employs more the head of the sail then the leach and because of that its head is slimmer then the heads of the other two . The top halves of the Ezzy masts are also softer then most other brands so they can bend more . The downside of this aproach is that the head will collapse completely sooner , shift the center of pull, stall the board and youll have to push hard with your front arm trying to keep the sail in place. The Gaastra is at the opposite end with a fat head and hard top mast relying heavily on leach trim-lenght and depth,which requires more precise downhauling which can get you more often into situations when you feel that you have too much or too little downhaul. And finally Sailworks is somewhere in the middle as you can guess from the picture alone. Head and leach work in harmony to shape a sail that feels very balanced and solid , doing its job well for many many seasons without really excelling in anything. Exactly what a freeride sail should feel IMO -making life easier and fun for everyone from intermediate to expert in flat and in chop . The optimal SDM mast is supposed to be the Joystick and the RDM -the Nolimitz Sumo, but a range of constant curve and moderate stiffness masts from other brands work also more or less-Gulftech, Chinook, Powerex etc. I'm a RDM diehard and I'm using curently a Cinook, Ka and Sumo for the Retros and Revos.My beloved Gulftech 100% unfortunately broke recently.
