Hey everyone,

I was wondering if anyone could please help me with choosing a suitable mast for my Gaastra Matrix 6.5 2007 model sail. Although it is 2007 it has never been used (long story) and so we need a new mast that will suit it. The recommendations printed on the sail are: IMCS 25, mast 460, luff 466, base 6. However, I don't know whether it needs a constant curve mast or a progressive curve mast? I tried putting a progressive curve Neil Pryde X3 460 mast (ICMS 25, carbon content 30%) into the sail but when I rigged it with this mast (trying different levels of downhall and outhall) the batons kept projecting behind the mast. Would this be because the sail requires a constant curve mast? Or would this just be corrected once the sail and batons actually get some wind in them and are stretched out a bit? Any help would be greatly appreciated.

Cheers,
Mark

Gaastra masts of 2007 or earlier, as well as Maui Sails masts should work well.

That sail needs a 'stiff top' mast, it's explained a bit better here:

Try a Gaastra Ignition 75% (yellow sticker). A cheaper alternative would be the Gaastra 55% (green sticker). These will work a lot better than the NP mast. Each brand sets better on its own designed masts.
Fiberspar or Maui Sails will work fine too.
