Replace Dorade with Solar Vent

I’m considering getting a solar vent for hunter 38. I know a lot of people install them in their hatches but I’m not super keen on blocking the light like that. I’ve got two thoughts- I could either replace my existing scoop on my dorade in front of the companionway slider with the vent or put it in the cabin top of the head.

I like the dorade because it’s out of the way and not likely to be caught on anything. It also wouldn’t allow water intrusion. I’m just not sure how effective it would be since it’s my only real source of ventilation right now.

If I put it in the cabin top in the head I’d ideally put it under the dodger all the forward under the eisenglass so it would still get the sun. I know this is less than ideal but I don’t want to interrupt the cabin top forward of the dodgerbecause it’s a good place for the dingy and moving around on deck to get to the mast.

I’m really unsure of what the best direction is to go here. Any thoughts, advice, or info on your install is appreciated.

Wouldn't it be simplier to replace your existing dorade vent with a solar vent in its current location and be temporarily inconvenienced by your dinghy stowed on the cabin top forward of the companionway?

I agree that the dorade is the simpler route. My only concern is if I’ll get enough airflow considering there is no other exhaust or intake since I only have the one dorade

Another option is an Air Only vent.

I'm thinking about doing the same on my 44 DS. Defender currently has some of these on sale.


Anyone know the size of the hole through the deck for the existing dorade?

The 4" size says that the 'above deck cutout' is 4 3/4"

I can help IF same as on my Hunter 46, which had a 4" SeaDog cowl and required a 4-3/4" cutout. I replaced mine with stainless steel cowls last year.

Thanks sail sfbay!

Mine looks exactly like the one at the link below from ebay. And it agrees that it is a 4 3/4" cut out. Nice.

Thanks! Those look really nice. The soft plastic on my original one looks pretty sad at this point.

I've had the Marinco ones in the past and in my experience they were not very reliable. The 4" one I had was replaced twice under warranty -- When the 4th one failed, I moved on.

On my current boat I have one of the Buchan stainless dorade vents. Very nice piece of equipment for not that much more than the crappy plastic ones.

I just ordered the larger marinco solar vent. It should be an approximate for for the existing cutout. I can always put the dorade back and move the vent if I decide it’s not working well enough.

1 more question- should I set it to exhaust or intake? It will be replacing my only vent so I think maybe intake but I’m not sure what would be best.

I replaced my dorade with the 4" Marinco a couple of years ago. Very little air circulation for as long as it lasted which wasn't very long. I would never buy another one.
