Dosvsi Boat Phone Clamp Mount – 360° Adjustable Marine Rail Phone Holder for iPhone & Galaxy

Meet the Dosvsi Boat Phone Clamp Mount, a versatile companion for anyone who navigates with a smartphone at the helm. Designed to adapt to the movement of water and the demands of everyday boating, this clip on holder puts your device within easy reach so you can monitor navigation charts, maps, and fish-finding data while keeping both hands free during busy moments on deck.

One key detail is a 360-degree rotating ball joint. Whether you need a landscape view for a chart or a portrait view for quick messages, you can tilt and turn the screen to the perfect angle without loosening your grip on the rail. The joint remains secure as you steer, trim, or adjust course, which can be handy when seas change direction unexpectedly.

The clamp base is built for real world rails. It fits rails from 0.7 inches up to 1.58 inches (18–40 mm), making it compatible with a wide range of helm setups—from small sailing boats to larger powerboats. It can also be mounted on other bars you might encounter in a gym, shop, or studio. The mounting method is tool-free, so you can set it up in minutes and move it as needed.

Double protection and stability

Dosvsi adds a double shield for your device and the mounting surface. Non-slip silicone pads grip the pole securely, while a thickened silicone strap sits around the phone sides or back, creating a cushioned anchor that helps absorb minor bumps on the water. The result is a steadier hold that reduces wobble when waves toss the boat.

Compatibility is broad and practical. The Marine Rail Clip supports a wide range of 4–7 inch smartphones, including popular iPhone and Galaxy models, and it accommodates many thicker cases. A one-button release makes removal simple if you need to grab it quickly. If your phone has a thicker case, you can pull the feet at the bottom apart to slip it in.

Easy installation and real world versatility

Setup is simple and tool-free: place the base on the rail, tighten by hand, and you are ready to go. It secures to sailboats, powerboats, pontoon boats, and fishing boats with a reliable grip that stands up to spray and rocking. In addition to marine use, the mount suits gym rails, mic stands, strollers, and more, giving you flexible placement across situations.

If you ever have questions or need a hand, our customer support team commits to replying within 12 hours. Dosvsi does not promise a guaranteed outcome, but it is designed to be a helpful, flexible option for on-water use and beyond.
