We've had lots of chat about mast characteristics in the past, bend, diameter, modulus etc, but recently I had cause to lift the Lee's mast and mine at the same time and notice the difference in weight.
Will being an expensive C-Tech and mine being a less expensive Aardspar one would expect some difference. Will also uses PBO uppers etc which will save weight.
Undeterred, i weighed mine at 7.6Kg - anyone got any views on wether this is excessive, or otherwise ?

Beans' C Tech was 2kg as just a bare pole, and it only failed in 5 places at once after 5 years... i think it was around 5kg complete when we weighed it at weymouth on the class scales, tom might have it written somewhere

Beans' mast was scary light. I dont remember it being particularly stiff though.

I don't think I recorded seperate weights when I had beans with everything on the scales. I suppose I could weight all the bits of the rig if needed? :P

I weighed my stick at Mike's a while back along side a Aardspar Hi-Mod stick for a Int Canoe. The Canoe used SK78 uppers ( that's all the string that was on it ) IMMS it weighed 6kg. My regular mast was, I think about 10kg? with wire ( wire may be 2 kg). I talked to Mike and Terry about the fact that when you subtract the weight of the wire there wasn't the sort of difference in weight you would have thought. And I think there position was that... Hi-Mod gives you a narrower section whilst using a similar amount of carbon ( hence only a slight weight loss ). Rather than a smaller section and less carbon = far less weight.
But don't quote me. It was a while ago and I wasn't top of my 'to remember list'.
