Letterbox Takedown video
The letterbox takedown is the safest spinnaker drop when sailing offshore or in heavy seas. By taking a spinnaker down over the boom and below the foot of the main, the spinnaker is controlled and kept out of the water, no crew are needed on the foredeck and the forward hatch stays tightly closed. This video shows how to set up for a letterbox and how to execute the maneuver.
