The humidity is the biggest challenge to being on a boat, I've got it down to 80% and working on getting it down to about 60 for a few hours, but I know within an hour of leaving it'll be 90+ again

At home I have the luxury of electricity and a great dehumidifier... Is that an option?
Potentially - I need a more consistent and reliable power supply completely installed first, which is a work in progress. I use those damp catcher baskets with the crystals in, and even a dozen of them in that space can't prevent the build up - I'm installing new solar powered fan vents this year which should improve things a bit, and by winter next year the power supply will be much more reliable - there'll also be a dump load which ought to provide some extra heat
I've tipped over too many damp catchers to be able use them 😂
