How to Make a Mainsail Cover Boom Tent
Stay cool and shaded when you’re at anchor or at the dock with a cockpit awning. We’ve devised a boom tent design that utilizes your mainsail cover to create a sheltered area over your companionway and extending to the cockpit. This is a very easy DIY and something even a beginner sewer will be able to tackle. Learn how to sew your own easy-to-install boom tent with this step-by-step, how-to video.
This boom tent is made up of two fabric panels that attach to the bottom of a throated mainsail cover using the twist-lock fasteners already on the cover. The panels stretch and are tied to the lifelines to create a shaded area in your cockpit. Since this awning makes use of the sides of the sail cover too, it uses less fabric than other cockpit awning designs.
Depending on your designed size, you can make your own boom tent with just 3-4 yards of 60-inch-wide marine fabric. In the video, we used 4 yards of 60-inch Sunbrella® Marine Grade fabric to create a boom tent for an Islander 37 sailboat. We recommend using the same material as the mainsail cover for the boom tent panels.
Watch the video to see just how simple it is to sew these panels and make a mainsail cover boom tent for yourself! Create this easy-to-sew project and enjoy a cool and shaded cockpit area on your boat!
