Clever tools for smooth sailing - starting with a drier hull!
Hull moisture control
The MarinerX Hull Dryer moves air through trapped hull spaces using the inspection port as the interface. It replaces improvised drying setups with a cleaner, repeatable tool for small boats.
Standard fits Beckson and West Marine 6" screw-in inspection ports, with adapter rings for RWO, Allen, Sea-Dog, Seaflo, and more to come.
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 and West Marine 6" screw-in inspection ports, with adapter rings for RWO, Allen, Sea-Dog, Seaflo, and more to come. Use the Inspection Port Guide to identify your port before ordering.
Standard offering fits Beckson and West Marine brand 6" screw-in inspection port with no adapter needed. If you have a different brand or style port, use an optional adapter to fit your boat. Check the Inspection Port Guide if you are unsure which style you have.
Powered via a 12V DC barrel jack connection (wall adapter included). No switches, apps, or setup required.
Actively drying enclosed spaces.

Controlled tests were run using a sealed container with water inside, simulating a wet hull. Each setup had either an open port, the Hull Dryer, or the Hull Dryer Mini. Tests ran continuously for over 24 hours. All tests were performed in a stable indoor environment.
Results:
- Hull Dryer: 9.0x faster than an open port
- Hull Dryer Mini: 8.3x faster than an open port
(lbs of water removed per day)
This confirms what users experience in the real world: fast, effective, airflow-optimized drying.

The MarinerX Hull Dryer is not intended for use in engine compartments or spaces containing fuel, fuel vapors, or other flammable substances.
It is designed for hull compartments where water intrusion may occur, but should not be submerged or exposed to direct spray or standing water.
Operates on 12VDC (AC adapter included). When using shore power, connect to a GFCI-protected outlet when practical.
