How big was the one that finally did the job for you?
My comment was based on scientific studies. Anyone's personal experience, alone, is pretty limited. I'm not sure where? Practical Sailor may be where I read the paper. They compared them all... look it up.
I have used little cigarette lighter units in each cabin
, until the buzz drove me to remove them. They fell WELL within the range of safe, but useless.
If you have a simple, small boat with no rubber, then a large unit with "no habitation" warnings all over it, would be OK while off of the boat, and effective. The smaller ones, as I said, are useless... all hype!
I suggest lots of ventilation, and wiping down surfaces regularly with a MILD chlorox solution. If off of the boat, in winter, in a cold climate, we put out 30 descant cups, (in nooks and crannys), and 3 small dehumidifyers, with numerous fans going as well. We also have EVERYTHING open down below, for more air movement.
This effectively "pickles" the interior, until the spring cruising season. When we still lived on the boat, however, that SUPER dry air below, created such dry skin issues, that after 12 years as liveaboards, we rented a place on shore.
