The Harken FlatWinder powered block is a self-contained, low-profile electrically-powered system designed for mainsheet traveler adjustment. This powerful block offers sailors significant benefits in mainsail control, providing the means to quickly depower the rig and delay reefing when wind conditions intensify. Functioning like a compact captive winch for the traveler, the FlatWinder is completely self-contained and operates in both directions. It allows the car to move anywhere on the track while keeping the traveler line off the cockpit floor. Harken recommends installing two space-saving, dual-function Digital System Switches, one to port and one to starboard, for activation from both sides of the boat.
Self-contained operation: The block operates in both directions, allowing the car to move anywhere on the track while keeping the traveler line off the cockpit floor.
Line containment: The wide-diameter drive sheave mounts on a sloped base, forming an angle with the sheave top to contain the line and prevent it from pushing against the block walls.
Progressive grip: The design exerts just the right amount of friction to keep wear on the line and components minimal.
Deck cleanliness: The FlatWinder eliminates the need for winches, making the deck cleaner and easier to navigate.
Compact motor: The compact horizontal motor is housed neatly belowdeck to maintain a low profile.
Integrated control: A Harken Dual-Function Control Box is included, serving as an integrated load controller and control box that conserves space.
Easy installation: With half as many wires as separate systems, the integrated control box is easier to install.
Voltage options: The system is available in 12V or 24V depending on the boat’s electrical system.
Exclusions: Switches and circuit breakers are not included.
