Sam,
I've been up the mast more times than a man should in two years, was secure for me. (Hedging my bets, I wore the spinnaker halyard clipped to my harness along with the main as insurance). Also, I'd be willing to clamber up for you if you're feeling any doubt. I'll be over at cyc on sunday launching the diesel with Bill Duggan if you'd like some help.
