Lorne, the Lewmar hatches have a "vent mode", you can close them partially and lock them that way as well. In vent mode you will have just a bit under a 1/2'' gap, no water gets in unless its raining sideways!

My boat is 2000 miles away and cannot verify it though. I just bought it.I would like to install solar vents to move air and control humidity.Where should I put them? Here are my thoughts.One in the bathroom due to showers and higher water use. One in the /14 berth to keep the temps cool and fresh air supply. And, finally one in the cabin. I think I need to avoid the large port over the V-berth due to water intrusion while sailing to weather, noise over the berth while sleeping, and finally, perhaps I might on occasion cover the port for darkness while sleeping and the vent would be covered.Anyone know what size vent is needed as I don't know the Lewmar hatch dimensions or material (Plexiglas?).Anyone have a better recommendation on the quantity and locations?Thanks. _______________________________________________ This list is supported by the generous donations of our members.
