RE: Help - Water in the hole!
I am currently trying to do the same with my starboard.
I noticed water bubbling from the vent when it was in the shade after a days sail.
The only point of water entering could have been through the vent plug as I have been noticing that the last few sessions Ive had to turn the plug more to tighten.
I have been leaving my board out in the sun (deckside up) and tipping the board upside down every hour or so and getting drops coming out of the vent hole.
But I never thought to put the vent plug in as the temperature cools.
Just a question though, why does the moisture travel to the vent plug while the board cools down?
