Character

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 34 — a sea-kindly motion in a seaway.

Comfort ratio 34
CoastalBluewater

1.82 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.82
LightHeavy

301 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 301
EasygoingPowered-up

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

Sail area / displacement 13.8
TenderStiff

34% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 34%

A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.

What the fleet has seen

The Whitby Boatworks 42, as the fleet has seen it

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

The Whitby Boatworks 42 is a 12.8-meter masthead ketch, designed by Edward S. Brewer and built from 1972 to 1988 by Whitby Boatworks and later by Ft. Meyers Yacht and Shipbuilding. This center-cockpit ketch is known for its spacious interior and liveaboard potential, featuring a 4.0-meter beam and a moderate 1.5-meter draft.1:17 While the boat performs well on reaches and runs, it is sluggish in light air and can be tender due to its 34% ballast-to-displacement ratio.3:56 Construction typically includes a balsa-cored hull and deck, which requires inspection for water intrusion.2:24 Common structural concerns include pop rivets in deck-to-hull joints and potential compression post failure under the mizzenmast step.5:31 Aging cruisers often require refits, including replacing glassed-in chainplates and updating electrical and plumbing systems. The Whitby 42 spawned later derivatives, including the Brewer 12.8 (Brewer 42) with an updated keel and rudder, and the extended Brewer 44.
