I have a 520 Gaastra 100 mast that I want to use in a 11mts vapor 2008 but still need some extra extension..... Any tip ( you was using Vapors and knowing you a little for sure you test other combinations than writed on the packs...) Hello,

Although its possible to build one larger than 50cm, I think it would be safer to build one at 45-50cm and then use your normal extension to get the extra 5-10cm. If using some extension inside your home-made extendor, make sure you have a good 15-20cm of extension still inside the extendor, otherwise you might cause it to fail with the large forces on only a small section of the extension.

Firstly, the boom would be a lot lower than normal in a section that isn't really reinforced so you might run the risk of breaking your mast at the boom attachment. Secondly, the bend curve of your mast will be really wrong as you'll have a very stiff bottom section with the extra base... it might work to 'get out on the water', but the early planing, handling, performance and stability of the sail will be severely compromised. You'd be better off finding a cheaper sail so you can get the correct mast for the sail if you can. Hi Ralph,

This was a heavy influence on me getting into formula windsurfing! Speaking of carbon xtenders, I have a question. I apologize in advance to all the racers who may read this. You might spew in your cheerios. I am on an inland lake and I got a FW board so I could increase my time in the straps on the plane. I’ve been using a world sails blast 9.5 on a 490cm mast. The mast is 100% and 29 imcs. I’ve been thinking of getting the biggest FW sail possible to further increase my time on the water. For me it is all about planing even in really light marginal air. Are there any sails out there that would rig reasonably well on a 490cm + 60cm fixed + adj. extension? Thanks for the great technical content. Great site!

I am yet to try this out... definitely the extendors are the way to go over conventional extensions which break. Great article.
