OK, I know it's a trawler forum, but this is interesting.
For you sailors that want to travel the ICW with a mast higher than 65
* This boat came in last night at Vero Beach.
* It has an 80' mast and 7'10" draft.
* Each water bag weighs 2000#
* It's been coming down the ICW.
* What a treat to watch the crew execute this maneuver.
