Mushroom Vent
A proper brass mushroom vent is a thing of wonder for a small wooden boat – good for a GRP boat too. Untwisting the “mushroom” lets air circulate below decks, keeping rot and mould at bay throughout the year. Owners often use two at either end of the boat, where it won’t get in the way. Just remember to close it when you go to sea. Or whenever you wash the roof! You can open and close these from below decks. Importantly they have a low profile which won’t catch ropes or stub toes. This 4in (105mm) version in heavy solid brass is 3in high and costs £105.
