Installed two Nicros and two Sunsei on our boat in 2008. Pros and Cons; Both move air and don't leak when it rains. Neither one of the models I chose can be removed, but have a feature to close them off from inside when needed offshore. The Sunsei requires you to slide the fan up inside the housing. The Nicro is shut by sliding a cylinder separate from the fan up inside. The Sunsei can be turned off or reversed easily with a switch while Nicro comes with On/Off switch and you need to change blades to select intake or exhaust. I think they would work offshore as well as a Dorade, but would expect some drips and not install one over my bunk. They remain dry in heavy, wind driven rain, and I only close them when I'm trying to heat the cabin. The Sunsei has a better neoprene gasket design, but is a larger diameter on deck and protrudes further into the cabin, and is slighter higher on deck. Noise level is slightly higher on the Sunsei than on the Nicro. The Sunsei have a rubber gasket around the outside glass solar panel that is starting to weather and crack after 5 years. One Sunsei fan would snag slack genoa sheets because of the location, so I glassed a couple wedges in front so sheets ride easily up and over. I haven't changed batteries, but the fans will run well past dark. I probably need to change the batteries.
Summary: check new designs for features before choosing best one for you.

I wish it weren't. I wish Nicro still made a removable one. You can still find the Nicro removables on eBay. There are other powered day/night vents available. Sunsei makes one. Don't know anything about it. Dennis C.

There is a collar attached to the boat with 4 screws, and the vent itself pushes into the collar. I'm pretty sure that the deck plate you use to seal up a Nicro cowl vent would also work to seal up the collar. I had to go to West Marine this afternoon to pick up some parts for my Zodiac inflatable, so I decided to look at the Nicro vents in stock to see if the design had changed to one that was not removable. The inventory of Day/Night Plus Solar Vents (the name has apparently changed) that they had is the same as mine. There is a collar with seal that attaches to the deck, a fan blade that can be flipped over to give either intake or exhaust, and a removable fan. The 3" moves 600 cu.ft/hour and the 4" moves 1000. See page 536 of the 2013 WM catalog, or search their website for part number 10447084. There are, indeed, two styles of Nicro vents. The other one is called a Mini Vent 1000, moves 700 cu.ft/hour when the sun is shining and gives passive ventilation if you have a breeze at night, and it is attached directly to the deck without the need for a "Nicro Vent Deck Plate". It IS cheaper than the Day/Night vent. Also see page 536 or search for part number 183733. Perhaps this is the one that Dennis was thinking about in his earlier response. BTW, there is also a Nicro Air Vent 500, which is passive only (moves 600-1000 CU.Ft/hr is a 15 knot breeze) and attaches directly to the deck. FWIW, it is only $49. _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com CnC-List@cnc-list.com
