If you left the transom drainplug open would that be sufficient enough to get air to circulate from the bow to stern? Another problem that I am faced with is there is no electricity in the shed my boats is being stored in as it was an old farm shed for cattle that my grandparents own.
Does it need to have 2 have two inspection ports? I only have one forward of the cockpit could that damage the boat.
