The Alberg 30 is a masthead sloop with a long keel, designed by Carl Alberg and built by Whitby Boat Works Ltd. from 1962 to 1987. It measures 9.2 meters LOA, with a 2.7-meter beam, 1.3-meter draft, and 4082 kg displacement. Over its long production run, the Alberg 30 was fitted with various auxiliary engines, including Gray Marine Gas, Universal Atomic 4 Gas, Bukh single-cylinder Diesel, Volvo Penta MD7A Diesel, and Volvo 2002 Diesel. Construction changes between earlier and newer versions included differences in mast braces, deck cores, drainage, and icebox design; earlier boats had laminated wood mast braces, masonite-cored decks, and upright iceboxes, while newer boats featured aluminum mast braces, balsa-cored decks, and top-loading iceboxes. Aboard *Sailing Triteia*, James sails his 61-year-old Alberg 30, *Triteia*, across the Indian Ocean, stopping in Sri Lanka and Indonesia, and anchoring in Kaneohe Bay, Hawaii.0:24 He reinforced mooring lines in Galle, Sri Lanka, to mitigate severe harbor surge and replaced his original sails with Contender Warp Tech fabric from Rolly Tasker in Phuket, Thailand, adding a fourth reef point.8:59 James also addressed a tiller failure on his Alberg 30, *Mighty Sparrow*, in New Zealand’s Cook Strait.32:34
