Re: Cooling the boat

It should have come with a batten or a dowel that helps hold the scoop open at the bottom and fits across the hatch but under the deck.. then hoist the 'scoop' on a halyard or a pole lift and orient it to the wind, using tension to keep the dowel tight to the deck.

My Pearson 34 has a West Marine through the hatch ventillation (a wind scoop) but I can't figure out how to put it up. How do I attach it to the forward hatch? Thanks!

Re: Cooling the boat

i use green plastic tarps, and i have a screen in green which needs refit, as was from a 47 ft sloop and i have a 41 ft ketch. usually i use 3 layers of these green plastic tarps and the boat stays cool.
dont leave any of the surface uncovered as sun bake sit badly. tarps prevent oxidation by sun baking, and keeps air flow good -- even act as a wind scoop if you figure your wind direction and coverage. for rain i use a huge silver over brown tarp--those shed silver stuff and only last one season here.
i also have canvas and screen finally finished...i just need window/port screens for bugs now.
\i dont have pix as my transfer mechanism died and i need to find a new universal card reader for that function. those items are difficult to find in mexico, for some reason....i love the lowlife look i achieve with these plastic things covering my boat...LOL

Re: Cooling the boat

We use a hatch cover as you described out of sunbrella to help avoid the early morning light as well as keep the sun off the hatch. It also allows us to leave a hatch cracked for ventilation in the rain.

Single centerline batten, corner grommets and shockcords, suspended from the pole lift or a halyard.

btw--my plastic tarps do not rattle. tie em so the plastic is tight and no rattle. rattle means the high winds will tear it. torn tarps allow sun and rain inside boat. that is not an option.
No chance of a photo of this setup?

Silver tarps--best thing since sliced bread!

Re: Cooling the boat

The effect was very pronounced and was def air flow. I could stand in the doorway to the V-berth and feel a serious draft up the hatch.

Re: Cooling the boat

Silver tarps work better than blue and they seem last longer in a high UV zone.

Re: Cooling the boat

Try keeping the sun off the boat first. Just go to Walmart and pick up a couple tarps of various size. Also pick up some of these to secure the tarps down. Run lines where needed to create "structure" for the tarps.

It'll dramatically cool down the boat. The cheap tarps probably won't last more than 1 season, but if they work then you can look into a more long term solution like some proper canvas.
