Nicro 24hr
Jerry, I'm a fan of the Nicro 24hr vents to keep the air circulating through my boat 24hrs a day no matter what the wind is doing. I have set up the intake in the forward hatch and 1 or more exhaust vents in the highest possible part of my last 4 boats. Because the fans themselves are Not powerful, I think it is important to set them up to help the normal convection currents in the boat move the air through the boat. Suck it in low and blow it out high. I had a bad experience with the standard 24hr solar in the forward hatch while motoring directly into steep waves because the waves breaking on the bow just like a beach rolled right up and in the vent. Previously I had crashed through (quartering) waves while sailing big enough to soak me at the wheel with NO leaks - but it can happen. I should have taken out the vent and put in the supplied deck plate. I have since replaced the forward hatch vent with the Nicro Powervent 2 or 3000 - what ever the model is that is square and has a switch and a sliding sleeve that totaly blocks any possibility of leaks. Pouring or wind blown driving rain has also never been a problem with any model. In 8 years on 4 different boats lines snagging on the forward hatch vent happen no more frequently than snagging on the hatch itself - maybe a couple times, so I ran a little screw through the sides of the solar 24hr. The Powervent is set up differently so it can't just pop off. Expensive , but worth it to me.Stan"Christy Leigh"c320 #656
