Hull Dryer - MarinerX

What Is the Hull Dryer?

When water gets inside the hull, it can really weigh you down and risks damage to your boat. Drying out the inside of the hull usually meant cobbling something together. We designed a clean, purpose-built solution—and tested it to optimize airflow and drying performance. The MarinerX Hull Dryer fits securely, works efficiently, and simplifies the whole process.

The MarinerX Hull Dryer actively removes moisture trapped inside your boat’s hull using the inspection port as an interface. It's ideal for small craft such as Sunfish and Laser sailboats and any other boat with similar access points.

Standard fits Beckson 6" screw-in inspection ports, with adapter rings for RWO, Allen, Sea-Dog, Seaflo, and more to come.

What Boaters Are Saying

“One of the most common problems I find with older boats is rot and water buildup in small crevices under the hull. It’s so hard to get this moisture out without cutting the floor apart—until I found MarinerXTech and this amazing product! It’s truly changed the game by drying out the hull, helping avoid saltwater damage, and keeping boats on the water longer. I can’t recommend it enough!”
– Nick, Boat Captain, South Florida

“Dryer arrived today. Looks well built. I may not be able to try it on my Sunfish until early May but will let you know how it makes out.”
