I recently purchased a 23' cruiser - it has a small 2 berth cabin
which is basically open to the below deck
area under the cockpit
, and locker in the stern which is basically a bunch of empty space above the bilge
with a shelf for the 6 gallon plastic gas tank next to the tiller shaft.
Whenever I open the cabin
or locker there is a very strong gas odor
and the gas tank itself is 'wet' with what appears to be gasoline. The vent is closed to the tank, and the boat has minimal ventilation - just through a louver on the companionway
I realize better ventilation is in place, but why would gasoline be condensing onto the tank in any case? If there is some gas in the bilge
(it's very dry) wouldn't it eventually evaporate and escape and work itself away if there is no ongoing leak (which i see no evidence of)?
