A classic marine-grade brass push-button switch for 12V systems, normally-off (momentary ON) type. Comes with a protective rubber cap for water resistance and durability. The solid brass construction with chrome plating ensures longevity in harsh marine environments. Mounts in a standard 22 mm hole, ideal for horn or engine start buttons and other momentary controls on boats. Heavy-duty contacts allow reliable high-current switching when needed (e.g., starter solenoid activation).

A heavy-duty two-position toggle switch made of brass with a chrome-plated knob. Rated for 20A @12V, this switch is ideal as a master ON/OFF for circuits on board. It features a plastic chrome-plated toggle cap for insulation and style. The switch is single-pole and mounts through a small hole with a threaded bushing (approx. 9.5 mm diameter toggle shaft). Commonly used for battery switches, blower fans, or other high-current devices due to its robust contacts and reliable action.

Sea 300W hydrogenerator that converts a sailing yacht’s motion into electricity. The short 610mm leg is ideal for mounting on low transoms, keeping the propeller submerged for peak efficiency. Suited for boats up to ~35ft, this unit provides sustainable power for onboard electronics and batteries, greatly reducing engine runtime.

• 300W green power: Delivers up to 300W (24A @12V) of renewable energy, covering the electrical needs of small to mid-sized sailboats and cutting dependence on the engine or fuel generator.
• Short 610mm leg: Perfect for vessels with low transoms or open sterns – ensures the prop stays submerged even in chop, maintaining continuous charging. (A 970mm long-leg version is available for higher transom installations.)
• Efficient at cruising speeds: Produces roughly 100W (~8A @12V) at around 5 knots with minimal drag. Begins charging as low as ~4 knots, which is enough to power essentials like autopilots, navigation instruments, and lights while sailing.
• Smart controller: Includes a converter that auto-detects 12V or 24V systems, optimizes charging, and offers Bluetooth monitoring of power output. Features an input for a solar panel, enabling hybrid charging (wind + solar) for maximum energy capture.
• Lightweight & robust: Weighs about 6.3 kg, built with marine-grade aluminum and composites. Quiet and streamlined – generates energy without slowing the boat, and designed to be easily lifted out of water when not in use (e.g., in port or if you hit debris).

Watt&Sea 300W hydrogenerator with an extended 970mm leg, designed for boats with higher transoms or requiring a deeper propeller immersion. Delivers the same output (300W) and benefits as the standard Cruising 300, keeping your batteries charged on sailboats up to ~35ft, with minimal drag.

• 300W power generation: Supplies up to 300W of clean energy (24A @12V), meeting the consumption needs of mid-sized yachts and preserving battery health on long voyages.
• Long 970mm leg: Ideal for vessels with tall sterns, pushpits, or raised mounting points – ensures the prop stays submerged even in waves or when heeled. (A 610mm short-leg version exists for lower transoms.)
• Peak efficiency: Produces ~8A (~100W) at ~5 knots and increases output at higher speeds. The longer strut does not compromise thrust – drag remains very low, with no noticeable slowing of the boat.
• Auto 12/24V controller: The smart converter manages charging, compatible with 12V and 24V systems, featuring Bluetooth monitoring and an extra input for a solar panel to enable hybrid charging.
• Versatile & robust: Same lightweight design (~7.0–7.5 kg) in anodized aluminum and composites. Easily lifted from the water, nearly silent operation, and backed by a 2-year warranty – an ideal companion for any cruising yacht.
