The correct size and classification for a vessel depends on its length and USCG classification, not a generic recommendation that applies across every boat.
A center console and a larger cruiser have different requirements based on their size category, and getting this right matters both for compliance and for actually having adequate coverage on board if it’s ever needed.
Extinguishers on a vessel need mounting hardware built to hold up against saltwater exposure, vibration, and motion in a way standard indoor brackets simply aren’t designed for.
Corrosion resistance matters more here than almost anywhere else extinguishers get installed, given the constant saltwater and humidity exposure a boat sees over a Florida season.
The same annual inspection interval applies to marine units, though the environment they operate in means wear and corrosion are worth checking for more proactively between service visits.
A quick visual check before heading out, beyond the formal annual inspection, is a reasonable habit given how much more exposure these units see compared to one mounted indoors.
