windy plus!!
Bad luck with Billows mast but in defenec i will say that out of the 100 or so of these that i have had only two have broken on first rig.
THe rest have stood up relatively well , with the occassional break as all masts do.
We have all seen Naish, NP and severne break on first use AND THEY COST DOUBLE/TRIPLE the price of the billows mast.
