Now that I have fitted a boom bag to my Compass 28, I have an oldish but perfectly serviceable blue cover to give away.
I'm in Melbourne, call me on 0411-230-060 if you're interested.

The boom bag is fantastic for an aging solo sailor. What used to take quite an effort up on deck, and was sometimes quite hair-raising out in the big stuff, now happens in about 30 seconds from the luxury of the cockpit, except for the final zip-up.
Cheers, Graeme
