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 9.2-meter masthead sloop with a long keel, designed by Carl Alberg and built by Whitby Boat Works Ltd. from 1962 to 1987. Its long production run led to variations in construction, including different auxiliary engines, mast braces, deck cores, and icebox designs. Crews sail the Alberg 30 for extensive offshore passages, including transiting the Indian Ocean and circumnavigation attempts. Aboard *Sailing Triteia*, the crew sailed over 16,000 miles on original sails before replacing them with new Contender Warp Tech fabric sails, adding a fourth reef for storm conditions.1:30 The Alberg 30’s robust design allows for anchoring in challenging locations like Kaneohe Bay’s submerged sandbar and navigating crocodile-prone rivers in Australia.38:15 Sailors reinforce mooring lines with chafe protection in surge-prone harbors, as seen in Galle, Sri Lanka.13:56 Solo sailors like Jerome Rand, preparing his Alberg 30 *Mighty Sparrow* for an Atlantic figure-eight voyage, address issues such as tiller failure in 45-knot winds. Crews use drogues to stabilize the boat in rolly anchorages, such as at Hexham Island and Middle Percy Island, Australia.13:51
