We were asked by another cruiser when we anchored out in Culebra earlier this year if we were crazy on account of our lack of wind scoop. The boat stays reasonably cool when you are under way, and we’d stayed in a lot of marinas where we can run the air conditioner, but when you are on the hook the main cabin can be stifling when the sun is up.
We bought our first wind scoop here in Grenada at Island Water World and the temperature difference in the kid’s room was immediately noticeable on windy days. The wind this time of year seems to blow pretty consistently during the day, which is when you need it most with the sun beating down. We haven’t tried measuring it directly, but the apparent temperature difference in the v-berth is about 20 degrees Fahrenheit with the scoop up and the wind blowing modestly.
The scoop we purchased wasn’t terribly expensive, but one of the things we’ve found ourselves with out here is plenty of time so we decided to try making one for our cabin using some sailcloth from an old trashed jib that had been sitting in a locker since we bought the boat. It took a few hours to hand stitch pockets for battens at the top and bottom of the scoop, and to hem the edges. We were able to save a little time by cutting our patch out of the old sail where a nice reinforced grommet had already been added to the sail cloth for the attachment point at the head of the scoop. There is no telling how long it will last, but the effort was worth it as today was the first day that we were able to take a truly comfortable nap in our cabin with the sun high in the sky.
