Hi
I sail an I-17R, and I just want to share my safety tips. I'd like to know if any other UNI sailor takes some extra precautions too.
When I sail for fun (read non-racing), I always my standard Life vest. It is fitted with a Knife (cutting lines, square end), some spare parts (pins, ropes, shackles...) , my new VHF to call for a club towing

or MAYDAY (ship happens) I also have a small Strobe for when the lights go 'out'

From 15 knots, I wear an helmet. I don't know why they've designed a brand new UNI-Rig with a boom

My helmet also does a great job for Sun protection. I also wear a safety line I can use to attach myself to the boat. It is mainly designed to tie me when I flip over, just in case I loose my grip and the boat drifts away (never again!)
So, am I a wussy, or do you guys put lady Luck on your side too ?
Happy Sailing !
