Damp rid in the summer (in the boat)... Some kind of simple heater in the winter, and humidifier.
That is a tough environment, but I believe if you keep the dessicants up for the summer in your guitar cases you'll be OK.
A custom roady case for you amp, again with drypacks in the summer you should be OK. Remember to change them regular.
