The tropics are hot and humid. Many cruisers who live aboard their boats during hurricane season or other long periods tied up in marinas, make life a bit more comfortable by judicious use of good old American air conditioning. Here’s how it’s done in Mazatlan, where most all the liveaboards run AC at least part of each summer day:
1. Buy a small air conditioning unit (8000 BTU for a 40-foot boat, for example), in the dead of winter. We got ours at Home Depot in Mazatlan at their December 31 end-of year sale. Screamin’ deal, man.
2. Find a place aboard to store the AC unit you just bought, until you need it next June.
3. Now that it’s June & you’re in a marina for hurricane season, pull out the AC unit & find a good hatch to hold it. We used the overhead hatch in the saloon.
4. Go back to Home Depot to get some 2×4 pieces to support the unit, some hose to drain the condensation off the side of your boat, and some insulation in which to encase the AC unit for maximum efficiency in sunlight and heat.
5. Use lots of duct tape to hold everything together.
6. Get a crew member to sew a Sunbrella cozy for the AC unit, the better to hold it all together and protect it from the elements.
