I also recommend buying a used carbon boom. All aluminium booms that I ever had broke after some time close to the head, sometimes twice a year in the early 2000s especially the North Silvers and Tecnolimits Ergal . I switched to Al360 and Severne Carbon booms later on and never had issues anymore. The Al360 carbon is 15 years now, regripped, clips are multiple times renewed and that thing just works and is since 5 years my spare boom. Those aluminium booms can bring you in trouble and are seriously dangerous if you don't windsurf in knee deep flat water.

I'll take a look next time I rig.
you're probably right. I did adjust bottom battens which were loose. Then looked at the second batten from the top which did seem a little loose but decided to leave it. I usually leave the top battens relatively loose. Not sure why I do. The wrinkle in the head when under down hauled really stand out in the photo. I'll grab another photo after adjusting the top battens with everything set to neutral 0/0

ill also get a photo from the side as that shows the profile better. It's got more profile than it looks in the photos.


On pictures it sometimes look more dramatic than in reality. In general I prefer more tension in the bottom battens and use lower tension the further I get to the top. The lowest batten for example 1-2 more rotations after the wrinkles are gone, the one above the boom only half rotation after the wrinkles are gone. On the top battens I just remove the wrinkles and thats it. After some sessions I'll check if something has changed. Cheers

Just a minor comment. As in the rigging thread about the Blade the batten tension especially on the top battens is to low. Beyond that these new Simmer sails looks fantastic. Thank you for the valuable comparison against the S1 Pro. Interesting to see that after few years other companies like Goya and Simmer jumped onto the "new" laminate that Severne was using on the Pro editions since a few years now. Besides that the designers are able to create an incredible Sail feeling for the customers , I think there is also a fantastic business case behind that because most of those Sails are high price but also tend to simpler designs with less seams, less panels which result in less production steps. Don't get that wrong for me this is a win win for everyone in this niche market. Lets see when Goya removes the window above the 2nd batten (Banzais) because this would be the next natural step for them and finally also their design will be in line with the Simmer Carbons and Severne Pros.
