\n Refabricating all 12 of my portlight screens took me just one hour. After the glue dried and I trimmed the outside mesh flush with the frames, I had nice new screens for all of my ports.<\/span>\n Roger Hughes<\/span>\n\n\t\t\t\t <\/figcaption>\n <\/section>\n\t\t\n\n\n\n\n

“Nighty-night. Hope the bugs don\u2019t bite.\u201d <\/p>\n\n\n\n

My parents used this rhyme to tuck me into bed each night. I used it with my own children. It is particularly pertinent on a boat, because there\u2019s nothing more annoying than a mosquito buzzing around in a dark cabin, and the moment you switch on a light in the hope of squashing it, it vanishes into some small cranny\u2014until you switch off the light again. It\u2019s also not really ideal to spray a small cabin with insect repellent because you might be the one who gets repelled. <\/p>\n\n\n\n

The answer is to have bug screens covering all openings, particularly portlights and hatches, which you might want to open all night for ventilation. <\/p>\n\n\n\n

Most portlight manufacturers make mesh screens that fit their portholes. On my 50-foot schooner, Britannia<\/em>, we also have custom-made hatch screens that clip into place under the hatches. One fits completely around the main companionway doors, but it makes it awkward to get in and out, so we don\u2019t use that very often.<\/p>\n\n\n\n

\n\n\t\t\t
\n\t\t\t\t\t\"torn <\/div>\n\t\t\t\n\t\t\t\n
\n This torn screen is not of much use in keeping out the bugs.<\/span>\n Roger Hughes<\/span>\n\n\t\t\t\t <\/figcaption>\n <\/section>\n\t\t\n\n\n

Portlight screens need to be outside the hinged window glass and within the frame of the port so that when the window opens inward, they remain in place. As a consequence, they are subject to rain, sea spray and ultraviolet light, even when the port is closed. The thin mesh screens slowly deteriorate. <\/p>\n\n\n\n

Nearly all of the 12 opening-port screens on Britannia<\/em> had arrived at this deterioration stage, with some actually torn and needing replacement. <\/p>\n\n\n\n

My portlights were made by Beckson, in Connecticut, with the newer-type overcenter cams to lock the port. The fine mesh screen is glued on one side of an oval frame that fits into a groove in the gasket, forming the seal between the port body and the hinged window. Beckson sells replacement screens for $32.90 each, but with 12 to restore, I decided to look into repairing them myself.<\/p>\n\n\n\n

\n\n\t\t\t
\n\t\t\t\t\t\"Gluing <\/div>\n\t\t\t\n\t\t\t\n
\n For gluing the frame, contact glue applied with a flat art brush works best.<\/span>\n Roger Hughes<\/span>\n\n\t\t\t\t <\/figcaption>\n <\/section>\n\t\t\n\n\n

I bought an 8-by-4-foot roll of fine mesh bug screen (used for repairing swimming pool enclosures) from my local hardware store, along with some contact glue and a quarter-inch art brush.<\/p>\n\n\n\n

To remove the screen frame, it was first necessary to pull the sealing gasket completely out of its groove in the body of the port. Everything \u00adneeded cleaning in soapy water anyway, so while I repaired the screens, my wife cleaned the hinged windows. We soon had ports looking like new. (It\u2019s best to undertake this project on a day when no rain is forecast because once the sealing gasket is removed from the body, the window is no longer waterproof, even if it\u2019s locked.)<\/p>\n\n\n\n

Using an X-Acto craft knife with a new, sharp blade, it was a simple matter to trim the old mesh out from the frame. Then, I brushed a thin bead of contact glue all around the rim of the frame and placed it glue-side down on top of my mesh, pressing them firmly together. (It would have been a good idea to first place a sheet of grease-proof paper under the mesh so that any excess glue would not stick to the table, requiring xylene-based solvent to remove it.)<\/p>\n\n\n\n

\n\n\t\t\t
\n\t\t\t\t\t\"Trimming <\/div>\n\t\t\t\n\t\t\t\n
\n First, trim the mesh with scissors. Then, when the glue is dry, use a knife to trim it flush with the frames.<\/span>\n Roger Hughes<\/span>\n\n\t\t\t\t <\/figcaption>\n <\/section>\n\t\t\n\n\n

After a few minutes, I cut loosely around the outside of the frame with scissors, and then moved on to the next screen. Replacing all 12 screens in this way took me just one hour. I then left them all overnight so that the glue could thoroughly dry. <\/p>\n\n\n\n

After that, it was a simple matter of trimming the outside mesh flush with the frame, and I had nice new screens for all my ports. <\/p>\n\n\n\n

A squirt of washing-up liquid helped to ease the new screens into the grooves in the gaskets, and press the gaskets back into the groove in the portlight. I could tell if the gasket was back in place properly because the window would close like before. <\/p>\n\n\n\n

\n\n\t\t\t
\n\t\t\t\t\t\"portlight\" <\/div>\n\t\t\t\n\t\t\t\n
\n This typical opening portlight, and the rest of the portlights on your boat, can be easily repaired in a couple of hours\u2019 work.<\/span>\n Roger Hughes<\/span>\n\n\t\t\t\t <\/figcaption>\n <\/section>\n\t\t\n\n\n

We now know that no bugs can come in through the open ports. If we also fit the hatch screens and keep the cabin door shut, it is a fair bet that the cabin will be completely free of any nasty flying bugs. Ahh, sweet dreams. <\/p>\n\n\n\n

The screens cost $32.90 each from Beckson, plus shipping and tax; that would be a total of about $450 for 12 ports. My screen material cost only $10. A quart tin of contact glue cost $7, and the art brush was $2. Total cost: $19. It\u2019s a no-brainer for a couple of hours\u2019 work. <\/p>\n\n\n\n
