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 32 — a sea-kindly motion in a seaway.

Comfort ratio 32
CoastalBluewater

At 1.69 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.69
LightHeavy

395 — very heavy for her waterline, a serious load-carrying cruiser.

Displacement / length 395
EasygoingPowered-up

15.2 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 15.2
TenderStiff

37% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 37%

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

What the fleet has seen

The Alberg 30, as the fleet has seen it

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

The Alberg 30 is a masthead sloop designed by Carl Alberg and built by Whitby Boat Works Ltd. from 1962 to 1987, featuring a long keel, 9.2m LOA, and 4082 kg displacement. Its long production run led to variations in auxiliary engines, mast braces, deck cores, drainage, and icebox designs. Aboard *Sailing Triteia*, James sails his 61-year-old Alberg 30, *Triteia*, across the Indian Ocean, anchoring in surge-prone harbors like Galle, Sri Lanka, where he uses extensive chafe protection and distributes mooring line loads.0:24 He also anchors in remote locations such as Kaneohe Bay, Hawaii, and the Endeavour River in Cooktown, Australia. *Triteia* has sailed over 16,000 miles on its original sails before James replaced them with Contender Warp Tech fabric sails from Rolly Tasker, adding a fourth reef for storm conditions.0:26 Aboard *Sailing Into Oblivion*, Jerome Rand prepares his Alberg 30, *Mighty Sparrow*, for an Atlantic voyage, having previously experienced a tiller failure in 45-knot winds in New Zealand's Cook Strait.watch
