How to Make a Boat Windshield Sunshade
If you have a boat with a large windshield, you know that the sun can really heat up the cabin. To keep it cooler down below and to protect the seating and dashboard inside from the sun’s harsh UV rays, you can use a windshield sunshade on the outside of the windows. A sunshade will not only block light from your cabin but it also provides an extra level of privacy. Making your own custom windshield sunshade is a straightforward sewing project that will give you a taut, custom-fitted screen. We’ll show you how to sew your own boat windshield sunshade step-by-step in this how-to video.
We recommend making your sunshades out of a marine mesh fabric. These fabrics filter the light to keep you cooler and provide privacy while still letting you see out, and take advantage of the view from your boat. For our shades, we chose Phifertex® Plus mesh in black, which offers about a 90% shade factor. To allow more light into your cabin, you could also opt for a traditional Phifertex Mesh with a shade factor of about only 70%. We should point out, that while Phifertex Mesh doesn’t let people see into your cabin during the day, at night when you have lights on in the cabin then silhouettes can be seen from outside. To give you a better idea of the privacy and visibility with the Phifertex Plus fabric we used, we filmed a short video to show you exactly how these screens perform during the day and at night.
Our windshield cover features three distinct pieces: two side panels and one main panel that stretches across the entire windshield proper. This main panel was made in two pieces that we seamed together and features Velcro® flaps along each side to attach it to the side panels. The side panels are optional and are set up in such a way that they look seamless when installed, but can easily be left off as well. In addition to the Velcro, gypsy studs are also used to create a smooth transition between the side and main panels.
The sunshade is secured to the windshield via snap fasteners. On our boat, we didn’t have a clean area in which to drill into the fiberglass to install screw studs for our snaps so we opted to use YKK® SNAD® adhesive-backed studs instead. We recommend using a plastic SNAD wherever possible on flat surfaces. Plastic SNADs are not suitable for curved or uneven surfaces; in these instances, silicone SNADs should be used instead. In the video, we explain in detail how to properly prime the surface for these studs and how to install them for the maximum hold. We strongly recommend that you use 3M™ Tape Primer 94 Adhesive Promoter before installing the SNADs. Using the primer will result in the best adhesion results over a long period of time. We also show you how to use the Quick Fit Kit to accurately position the snaps in your sunshade to perfectly align with the studs already on the boat.
In this video, you’ll learn how to pattern, sew facing, bind the edges and install snaps to make your own windshield sunshades. The video demonstrates this process on a powerboat, but the same techniques can also be used to create sunshades for an RV.
Since filming this video, we now carry Soltis® 86 by Serge Ferrari, an open weave mesh that is ideal for sunshades in boats, RVs and homes. The fabric's excellent dimensional stability means you can use fewer snaps in your windshield installation without the mesh stretching or wrinkling — this means fewer holes in your boat.
