Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her heavy displacement on a moderate beam gives 26 — a moderate, middle-of-the-road motion.

Comfort ratio 26

2.04 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.04

Displacement / length 319
EasygoingPowered-up

14.5 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

40% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 40%

A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.

What the fleet has seen

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. It shares its hull with the earlier Seahawk 34/35 and Falcon 34/35 models and was available in both center cockpit (the more popular version) and aft cockpit configurations, with only five aft cockpit versions built. A twin keel variant was also produced. Aboard *Sailing Zephyr IV*, the 81-year-old owner Dave sails his Oceanquest 35, *Zephyr IV*, extensively along the English south coast, including passages from Plymouth to Falmouth, Dartmouth to Plymouth, and Portsmouth Harbour to the Nab Tower.watch The boat has encountered varied conditions, from light 9-knot winds requiring motor-sailing to 30-knot headwinds and rough seas that forced a return to shelter. *Zephyr IV* has achieved speeds of 7.5 knots on a beam reach in 23-knot winds.8:35 The crew has navigated narrow river channels, running aground in 1.3 meters of water in the River Fal, and transited well-buoyed passages like the Looe Channel.0:19 Dave has addressed maintenance issues such as a Volvo Penta 2003 engine's overflowing freshwater cooling header tank, traced to a blocked thermostat bypass nozzle, and replaced masthead lights and a wind indicator using an eWincher electric winch handle for the bosun's chair. *Zephyr IV* was involved in a collision in Portsmouth Harbour's Fairham Channel when a sudden squall overpowered the helm, bending the anchor shaft and damaging the stemhead fitting and pulpit.5:06
