Just remember that when you get there you still need water. Drinking water can be very suspect in Mexico, and sitting in your tanks will make a nice breeding ground for organisms that you did not really want. Just be careful.
A very good point, and one I've struggled with. I am planning to bring the strongest filtration system I can possibly find so as to de-bug the water going back into the tanks. I also have a small Brita unit attached to my faucet. I'm sure given the 200 other boats in the Ha Ha I will find out where to get decently clean water that I can then zap clean. The UV sterilizer is a good idea. Will look into that as well.
Gary1 - What's up with that delivery crew? Sounds like a bunch of hooligans.
