12V Marine Fan with Rail Clamp Mount – Ø15 cm Clip-On Fan

This marine 12V fan is the perfect accessory to improve comfort on board during hot weather. It’s designed with versatility in mind – thanks to its sturdy clamp, the fan can be attached practically anywhere: on a yacht’s guard rail, a hatch frame, the side of the cabin, or even a table edge. This means you can easily move it around the boat depending on where you need a cool breeze.

Power & Consumption: The unit runs on 12V DC, making it compatible with the electrical system of nearly all boats (and cars/RVs). At ~15 W power, the fan draws relatively low current – roughly 1.25 A at 12V, which is a negligible load on a typical marine battery even for extended periods. Most models come with a cord (about 2–3 m) and a cigarette lighter plug, so setup is plug-and-play: connect it to your boat’s 12V accessory socket. If you prefer a hardwired installation, you can remove the plug and wire the fan into a fuse panel or switch.

Cooling & Comfort: With a blade diameter of ~15.4 cm (6"), the fan is large enough to move a noticeable amount of air yet compact enough to not be in the way. It’s ideal for ventilating the cabin before sleeping, circulating air in an RV bunk area, or providing a breeze in the cockpit on still days. The fan does not oscillate side-to-side (unless specified otherwise) – this model is fixed in place, but the head tilts and swivels manually. You can point it directly at yourself for a personal breeze or toward a general area for ventilation.

Clamp Mounting: The big advantage is that no drilling or permanent mounting is required. The clamp is like a large clip with a wide, rubber-padded mouth that grips rails, poles, or edges (up to ~2–2.5 cm / 1" thick). This makes it especially useful on sailboats, where you can clip it to a companionway hatch or a grab rail, and on open boats – to a Bimini top frame or seat backrest. The clamp has a screw-tight or spring mechanism that provides a strong grip, so the fan won’t slip even when the boat vibrates or moves.

Practical Use Cases:

• In calm weather at anchor or dock, clip the fan to the rail and aim it at the cockpit seating area where crew are relaxing.
• While sleeping in the cabin, attach the fan to a suitable edge (like a shelf or door) and direct it towards the berth – it will circulate air and help prevent stuffiness and condensation. The fan’s noise is minimal, providing a gentle hum that many find pleasant as white noise.
• During fishing on hot, windless days, aim it at the helm or fighting chair to keep cool while you watch the lines.
• In an RV, if you’re camping off-grid, this 12V fan is invaluable – clamp it to a table or cabinet and power it from the battery to get a breeze inside a tent or camper where AC power isn’t available.

Durability: Made of quality plastic, the fan is built to withstand marine conditions – the materials won’t rust, and the blade and guard are robust polymer. It’s advisable, of course, to shield it from heavy rain and not leave it permanently outside in foul weather, since it’s not a fully waterproof device. But normal splashes and humidity are fine. When not in use, you can easily stow it in a locker.

Safety: The fan features a safety grill on the front and back to prevent fingers from touching the blades. Nonetheless, as with any fan, be careful not to place very small loose items near the intake that could be sucked in or hit by the blades.
