No see um hatch covers

[SailFastTri]

Check out oceanair screens. I have no affiliation, but my boat came with them, and they are the golden standard. A little pricey but they look and operate superbly.


I would also suggest you consider a full cockpit enclosure for when the flies or other insect become unbearable. We constructed one from a garage door mesh screen covering (about $25 online) and it saved our sanity quite a few times when the biting flies were hatching and swarming all over the boat (they hatch in the water). Get some curtain weight beads and sew them into the lower hem. Use clips or snaps or clothespins or Velcro or zippers etc. at the tops. Anything that works.
