The boards look sick, can't wait to try the new quad 9. Why only big sizes in haiku package?- maybe not supposed to be jumped as much...
As for the sails I am a bit skeptical- less monofilm means less reactivity, less skin tension. Apart from the mast- monofilm is the motor of the sail. No matter how durable expensive and sophisticated are laminates, nothing beats monofilm. Otherwise race sails would have abandoned monofilm long time ago for good. The 24/25 wave sails were a good compromise between monofilm/scrim surface area and proper positioning of monofilm with a patch above the longest batten- a very important place for the behavior of the sail. Lets see what the reviews will say. Cheers
What do you mean by "reactivity" ? Power up? Depower? It's a bit vague id like to understand your description more? what characteristic do you think monofilm is giving you that laminates don't? Do you have examples or can you describe the feeling of laminates sails relative to film?
Monofilm is thicker than the 2 thin films of the laminates, therefore it is stiffer. When pressurised it stretches less then is more reactive to gust.
Carbon laminate is even stiffer if the connection (bonding and or sewing) is well made, and only in the direction of the carbon strippes.
I guess this makes it difficult to use properly in slalom sails, that's why Monofilm is still used.
I guess if a sail designer had unlimited time and budget to design the best slalom or speed sail, he would end up using carbon laminate, or even more 3di. But FEA and CFD are expensive and difficult to use properly on a windsurf sail.
