No to ozone generators on boats
Your suggestion to use K.O. to get rid of the musty smell in lockers is a good one...I use it for that too. It's very versatile product...also works on cushions (let 'em dry in the sun for a day) and pet accident sites. However...An ozone generator on a boat is a bad idea. The health hazards from it may be arguable, but it's UN-arguable that ozone is highly corrosive...AND it's even more destructive to rubber, neoprene and hoses than it is to metal.Besides, ozone is just an "air freshener"...it doesn't eliminate the source of any odor...and the only way to get rid of an odor is to get rid of whatever is producing it. Otherwise, you're stuck with continually trying to purge that odor from the air.I recently heard a great idea for dealing with humidity in boats, but it does require shore power: a household de-humidifer with a drain (this takes a little modification of any basic table-top unit) routed overboard. Inexpensive...doesn't generate any corrosive chemicals...and the people who've done it, even in south FL say it works--no more mildew in their boats.
