What the fleet has seen

The Westerly Yachts Ltd. Oceanquest 35, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Westerly Yachts Ltd. Oceanquest 35 is a 10.8-meter masthead sloop designed by Ed Dubois and built by Westerly Yachts Ltd. from 1993 to 2001, sharing its hull with the earlier Seahawk 34/35 and Falcon 34/35. It was available in both center cockpit and aft cockpit versions, with only five of the latter produced, and a twin keel variant with a 3.92-foot draft. Aboard *Sailing Zephyr IV*, the 81-year-old owner Dave sails his Oceanquest 35, *Zephyr IV*, along the south coast of the UK, navigating areas like Portsmouth Harbour, the Solent, and the River Fal. The boat has encountered challenges such as a collision in Portsmouth Harbour due to a sudden squall, engine issues with a Volvo Penta 2003, and running aground in the River Fal due to outdated chart data.watch Dave uses the boat for coastal cruising, often with guests, and has undertaken maintenance tasks like replacing masthead lights and a wind indicator using an eWincher electric winch handle.0:26 The autopilot is effective in light air, but the boat requires manual steering in strong winds.19:22
