I've broken yesterday 2 100% carbon SDM 490 masts on the same day.
Bitter taste in my mouth ...
1 mast just snapped on the beach, while it was laying +/- 1 hour in the sun. I know I should not do it, but it happened.
The other snapped on the water after pumping, so I had to swim +/- half an hour.
My 8.8 race sail needs a SDM mast. I'm thinking of buying a 75% carbon SDM mast (in stead of 100%).
Do you think they are generally stronger ?
