The SC31 has 4, 1/4 inch,19 strand shrouds on either side, a split backstay, the headstay and the inner stay for the staysail. Of all of the deck stepped masts i have seen it has by far the most support. The mast itself is not very tall (~45 ft off the water) and it is very rugged. If i loose a wire for some reason it might stand a chance if i can get the sails down. If for some reason it goes overboard I have 2 hacksaws and a wirecutter onboard to cut it away.
I feel the same way as Jeff, the last thing i would want was a 200 lb 20ft peice of aluminum swinging around poking holes in my boat. If it's going over all is better than nothing!
On the other hand, I think the bottom of my compression post is soft. It is glassed to the keel so it is hard to see but there is definate compression going on...like the bathroom door won't shut in heavy wind! I think I am going to take the mast back off this winter and jack up the cabin top, then cut out the lower section of the compression post and replace it with either metal stock or a fixed jack. Any ideas? All's good though, it isn't getting much worse so i think i can sail out the season. I was out yesterday with a reef in the main and the staysail in 20-25knts! I brought a powerboater friend who had NEVER sailed. He was hooked after the first upwind tack
