North Platinum Mast
 

What happen with this mast. I broke 4 in a year. Are they building by Neil Pryde factory?

What year were yours? I will avoid your year. I got 400 through to 550 platinums, had for about 3 or 4 years and no problems. Not heard of excessive breakages, just the odd one here and there.

3 of them 2010 model and the other one 2011.
