The handle switches off when not in use, and since it remains on the winch you can place the handle in the ideal position before undertaking your maneuver, thus granting you maximum power and comfort with the least amount of effort.
To manually adjust the last notches of the winch on a very tight sheet, you can reposition the handle as needed without ever letting go of it or removing it from the winch in order to apply traction and start over, using the same principle as a ratchet wrench.
It’s easy to use both in manual and electric mode, and doesn’t need to be removed and then repositioned, or even worse, replaced with another handle, to finalize your sail adjustments.
