Hi , David .vent holes , ?that is a good point .I was wondering should I make the little vent holes or not . Problem comes from temperature difference , so some condensation is possible inside voids . Some builders don¡¯t worry about it . I¡¯ll start thinking the least harmful way to make them . In the Tiki 30 cat I build once , vent holes were tiny ,about 4 millimeters and they were positioned high as possible inside the void , there is even a little hose connecting two compartments . In theory , water will not go trough small holes because air pressure holding the hole closed . Anybody has some thoughts on that matter?
