Jim,
That's exactly what I needed to hear. The jiffy-reef page you linked is great! I spent quite a while surfing for that kind of simple, direct instructions with photos, and I never found info as good as that.
I'm for sure going to seal my mast...I hadn't realized how heavy the water-filled mast would be, and I didn't know that most newer boats had sealed masts.
I think a traveler would help a lot. My mainsheet attaches directly to the rear crossbar.
Thanks for the help!
