Thanks for the tip Jeremy. I'll go back through the US Spars paperwork I have on the boat. We had a discussion over a few beers this past weekend, one of the other guys told me that we also need to have the boom at the correct angle which would tie into the vang issue.
I know I'm an old guy but I think that dropping the main into a stack pack would be much more dependable. I can't imagine having to deal with this if we were on blue water, things were turning to dookie and we needed to get the main doused.
