Hello, I am looking to add a powered ventilator to my boat. I would like to install a solar powered unit, like a Nicro powervent. I am looking for advice regarding size (3" vs. 4"), material (stainless vs plastic), etc. I see some are listed as having a shut off to prevent water from coming below. Others you are supposed to remove if water will be on deck? Any other advice? My boat is 28', and I was thinking of installing one in the hatch in the main cabin. BTW, the hatch is lexan, will I be able to drill a hole in it, or will that destroy the hatch? I could install the vent in the fiberglass hatch in the V Berth area. Thanks! Barry

Solar Vent

I installed a Stainless 4" Nicro in the lexan vent behind the mast on my Catalina 30 a couple of years ago. It has not leaked water in, even when doused, and is still going strong. It is the solar model with the rechargeable batteries, so in runs overnight as well. Cutting the plastic was not an issue. I used a Rotozip.

solar vent

I installed a 3" nicro solar vent in my forward hatch this spring. I would have used a 4" (want as much air movement as possible) but the dogs on the hatch prevented the use of 4". The way these vents are seated, they are easily removable with a cap that seals the hole when the vent is removed. When I wash the boat, I take it out and use the cap. The rest of the time the vent stays in and I haven't had any problem with rain getting in. I lake sail and don't get waves over my deck area so I don't know about that. I purchased a properly sized hole saw (it fits into a hand drill) and used it to cut through the lexan. It was not easy and required a pretty heavy duty drill. The tricks are: use a variable speed drill and cut slowly because the teeth on the hole saw will grab the plastic and twist out of your hand if you use too much pressure; tape both the top and bottom of the area to prevent the edges of the cut from splintering and; after you get the hole about half way through, finish it from the opposite side (this also helps prevent splintering. A dremil/rotozip may have been easier. The hatch is a good place for mine because the hatch has a screen so no bugs get in through the vent. Good Luck

I RECENTLY REMOVED MY SOLAR VENT IN THE FORWARD HATCH AND REPLACED IT WITH A COWL VENT, ATTACHED A PLASTIC PLATE OVER THE VENT (KEEPS THE RAIN OUT), I GET A LOT BETTER AIRFLOW AND THE CABIN IS COOLER. STILL HAVE TWO SOLAR FANS IN REAR OF BOAT BOTH SIDES CHECK OUT THE VENTILATION ARTICLES AT SAILNET.COM THIS SEEMS LIKE THE WAY TO GO IF YOU ARE ON A MOORING
