You should NOT have any issues with storing your boat where you do. N-NE winds are usually during dry spells, and rarely is the wind above 20-25knots. Now out of the S-SW, you can get them into the 80's during the everyother year worst case scenerio storm around here.
You may or may not want to winterize the water system. We do get week to two weeks at a time where it might stay below 32F for the whole time, but usually mid 20's at night, just above freezing during the day. As mentioned, if you will be around, worry to not worry, If not around, do so, and you will sleep better in Fl. I have yet in 15 yrs of owning boats and RV's to winterize per say these items. But I do leave the heat on.
Not much else to add.
Enjoy the time here in the NW.
