*turn up the cushions to let them air out.
*Turn everything off to the batteries but leave them in and the bilge pump
on "auto". It rains hard in Fl and can fill a boat pretty quickly... especially if it's sitting at something other than it's normal angle while on the hard
.(you dont know this boat)
* The little bees will fill your tank vents in a short time in the summer, dont know about any other time. Tape them. Stuff something in your exhaust
outlet so rats or insects dont go in there.
* If you can find a way to provide screened ventilation without water ingress.. do it.
*You're not in the storm season so I would just leave the mainsail
on the boom and covered.
*remove food and leave the fridge doors open.
*Forget using those bags of dehumidifier granules, they disappear in FL in just a few days it's so humid.
3 months is a quite short time really, so I wouldnt worry about fuel. Last boat I bought in FL had sat 3 years and still ran on the fuel. Most boats sitting in the marinas
probably have fuel older than that .
