In Sweden we have a range from small gnats (as the No-see-ums) up to regular sized mosquitoes. We don’t have any deceases such as Dengue fever or Zika but we all hate them anyway. The sound of a single mosquito in the cabin at bed time can easily ruin your sleep. To mount the screens is simple and everything is done from inside the boat even if the screen will be outside of the portlight. Open the portlight to 50%, pull out the screen so it comes on the outside. Adjust the screen so it covers all the opening of the portlight. Attach the magnet (a metal plate is attached with double-sided tape) to the portlight and adjust the portlight window so you get some tension in the screen. Done in a few seconds. After use the mosquito net can easily be folded down to a 1/3 of its size for storage. The screens only need to be bigger than the portlight opening. A portlight with opening <7½”x17” (180 x 430 mm) needs a screen 10” x 19” (230 x 490 mm). Since the screen is bigger than the hatch it’s also fits different shapes (square, elliptical, rectangular and round). Two sizes cover almost all standard portlights and brands. It’s easy to pick the right size. Imagine the perfect evening without mosquitoes.
