A lot of
liveaboard marina's in the Houston area.
Kemah has several. If your
offshore in the patch, you might check Galveston. I've stayed at Harborwalk Marina in Hitchcock, just across the
water from Galveston. As far as rules, be a good
dock neighbor!
Ah, I just reread and see you have a 31'
boat. Some marina's have limits on size, as in nothing smaller than 40' for
liveaboard, but make some calls.
