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.
well, i was really looking for actual felt differences, what you have given me is an explanation of why you think it does something, not that it actyually does do that thing or a description of how that thing manifests
so what does "stretches less" and "more reactive to gusts" mean in practice? so really we are talking about wave sails, so the stiffer more reactive sails in film ( if true)- what happens in a gust? do they accelerate quicker? power up quicker? feel more powerful? less powerful? go faster? go slower?
is there any video you could point to where we could see this effect? are there any sails that are noteably more reactive or less reactive that you could point to?
In theory a stitchless sail will react quicker to gusts than a usual stitched sail as the seams on a stitched sail will load up and stretch and the stitches will stretch and breath.
The sail may not necessarily be more powerful, that depends on how the sail is built and what shape has been built into it.
I'd say the most reactive wave sails are the Ezzy Taka's as they have a 3/4 batten which means they go completely neutral and then load up again and they have a massive wind range due to the fact that they can be tuned a lot more than most sails.
It's good to note that a lot of companies are now using carbon materials that stretch less and are lighter. How long sails last is a whole other story.
