I'm no expert at this, so don't hang me for what I may suggest. I have only once righted my SC solo, and I did it in knee deep water. I had a line thrown over the top of the wing, and at the time did not have the shroud extenders extended. Could I do it in open water? I don't know, but think it might be feasable. Oh, I also unfortunately tip the scales at 200#
Planning ahead for the event, I've made four lines that I've added a 1" diameter by 12" PVC pipe to each end. Basically, I thread the line part under the wings, two per wing, one forward and one aft. I also have made another grab handle from PVC and a stainless hook so that I can stand on the lower hull and reach up to pull the righting line handles out from under the wings. I keep this under the boat attached to another pole for easy access. Keep in mind these righting lines are loosely threaded and do occasionally drag behind the boat when slapped free by wave action.
I also made a power pole of sorts from a fiberglass pruning saw extention pole...$20 at Big Lots. For S&G's I padded it where it may impact the hull with a swim noodle when the hull comes crashing down. One end of the pole is tied off the the dolphin striker rod....the other to the back cross beam. I have another line that I can attach to either port or startboard sides of the dolphin striker to provide a leverage point and so the pole won't break. Another stainless eye was added to provide a connection point for a righting bag and some blocks, but I have yet ot purchase either. For the record, I have yet to test this, so I can't say for sure that it works.
As a last resort I have a modified shock cord righting system strung around under the tramp.
I know the boat was made to use the shroud extenders, and I believe Matt in saying they'd make righting a lot easier. However, due to a rather BAD experience, which may have just been a fluke, I'll never use them again unless there is no other option. Matt, you can mark me down as being once bitten twice shy .... No offense !!
BTW, Hurricanes still SUCK....I took my boat apart in fear of Hanna, and now Hanna is going to be a no show. Which is a good thing, but I missed some good sailing weather, and now we have IKE on the way.... Go back to Tina, Ike.
