Character

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

LivelySea-kindly

Her heavy displacement on a narrow beam gives 46 — a heavy, notably soft motion offshore.

Comfort ratio 46
CoastalBluewater

At 1.65 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.65
LightHeavy

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

Displacement / length 283
EasygoingPowered-up

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

Sail area / displacement 12.7
TenderStiff

23% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 23%

Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.

  • Heavier than ~91% of boats her size on file
  • Draws more than ~91% of boats her size on file
  • Beamier than ~97% of boats her size on file

Compared with 32 boats of the same type within a quarter of her length.

The Mason 63 is a 19.4-meter staysail ketch with a long keel, designed by Alvin Mason and built by Ta Shing Yacht Building in Taiwan since 1988.1:00 Displacing 29,211 kg, it is known for its robust construction, including solid fiberglass layups.5:01 Aboard *Be The Captain*, a 1984 Mason 63 named Tavega completed a 3,300-nautical-mile Pacific crossing from Hawaii to Half Moon Bay, California, in 17 days, maintaining 8 to 9 knots in 25-to-30-knot winds and 15-to-20-foot seas.16:55 The crew prepared for heavy weather by reefing the main and mizzen sails and shifting to headsails only, noting the boat's steady tracking through beam seas.5:10 Before a subsequent 3,300-nautical-mile Pacific crossing from Kauai to Vancouver Island and down to San Francisco, the crew inspected rigging, replaced worn halyards, serviced the Detroit Diesel 453 engine, and cleaned the seawater cooling strainer.2:03 During this passage, they addressed electrical shorts and a refrigerator pump issue, while performing mast maintenance.28:42 The vessel maintained average speeds of 9 to 10 knots while reefed in 15-knot winds.25:30 Crews utilize PredictWind and Iridium Go for weather routing and satellite communications.8:15
