I am assuming you will be fixing any bad electric, flashing & moisture issues... Being that close to water with high humidity I would lean towards Closed Cell - with that, if your wall assembly is properly done you could use open cell Quick word - the wall assembly should be done properly for both but it is more important with open cell. You may also wish to look into a rain screed detail, that will help eliminate a ton of possible issues down the road
