SeaSense Registration Letters & Numbers
Stay Compliant on the Water with SeaSense Registration Letters & Numbers
Every powered vessel on U.S. waterways is required to display a valid state registration number, and displaying it correctly is just as important as having one. Registration numbers are legally required on most powered vessels, and clear, compliant numbers make your boat easy to identify for law enforcement and registration purposes. SeaSense takes the guesswork out of staying compliant with straightforward, purpose-built registration letters and numbers designed for real-world boating conditions.
SeaSense Letter Kits: Simple, Waterproof, and Ready to Apply
SeaSense offers two distinct solutions to cover the most common registration needs on the water. Their peel-and-stick Letter and Number Kit is built for quick, hassle-free installation. Just peel off the back and press on — each kit contains four of each 3" letter and number plus 16 dashes, and is fully waterproof. These vinyl characters feature the standard 3" height and meet U.S. Coast Guard requirements when applied against a contrasting background with proper spacing. Whether you're marking a fiberglass runabout, a aluminum fishing boat, or a pontoon, the adhesive-backed format bonds cleanly to most hull surfaces.
The Inflatable Boat Registration Set: A Unique Solution
Where SeaSense truly stands out in this category is their dedicated solution for inflatable boat owners — a segment often overlooked by generic registration kits. The 4" x 24" Registration Set uses four suction cups and supplied adhesive to allow registration placement on inflatable boats, and includes two registration plates. This dual-attachment approach — suction cups and adhesive — gives inflatable owners reliable, secure placement without damaging the boat's material. It's a thoughtful, practical design that addresses a genuine gap in standard marine registration products.
