We have a monohull with AC. We use it in the marina due to mosquitos and heat. At anchor, even in the hottest months with low winds and high humidity, there are hours when we would like to use but never entire nights or days. We spent four weeks on our boat in October/November with rain a couple of times every night, that was occasionally annoying. But, my lady no longer has the hot flashes and I just pop up to the cockpit for a lookaround to cool off quickly.
