Glowfast Marine has expanded its line of glow-in-the-dark sail tape so that cruisers can now keep tabs on sail shape during night watches, the same as racers. According to Glowfast, its luminous draft stripes can improve sail handling and performance as much as 20 percent after the sun goes down. Coupled with the company’s wide range of clutch labels, safety labels and even glow-in-the-dark paint, the stripes also go a long way toward promoting safety.

The cruising tapes feature the same active ingredients as Glowfast’s racing tapes at just half the price. They require as little as 10 minutes of exposure to light to glow for up to 20 and can be re-charged with a flashlight. Lightweight and easy to install, they will last the life of a sail when attached correctly. Although the tapes can be easily seen from on deck, they are faint enough that they are invisible to the competition when racing offshore.

In addition to creating draft stripes, the tapes can also be used to mark spreaders, sail bags and telltales. A special lightweight spinnaker tape is available for marking downwind sails. For more on the Glowfast luminous sail tapes, click here.
