Sailing Zephyr IV · video

What this video covers

Dave and Bill test the performance of a new propeller on Zephyr IV during two days of sailing in the Solent. On the first day, the crew encounters 30-knot winds, exceeding the PredictWind forecast by nearly 10 knots.1:19 With a single reef in the mainsail, the boat reaches speeds of nearly 6 knots over ground while heading toward Calshot.1:37 On the second day, the wind remains shifty and gusty, reaching 22 knots as the boat makes 6.7 knots to windward.9:31 The crew notes that the new propeller improves boat speed and handling in these conditions.9:45 After beating to windward toward Cowes, the pair motors up the river Medina to pick up a mooring.14:29 The return trip to Gosport provides a calmer 15-to-20-knot breeze, allowing for a steady 5-knot downwind sail.15:06 The new propeller maintains effective propulsion and boat speed during high-wind gusts and variable conditions.
