The Beagle in the Bay of Islands 2024

And west the Beagle went again to reach the Bay of Islands on the east coast of New Zealand’s North Island on the 19th of December. Darwin was not nearly as impressed by the inhabitants here, commenting that the Maori natives were “savages with the character of a much lower order than the Tahitians” and many of the English settlers were of “the most worthless character” and “included runaway convicts”, not anticipating that less than 200 years later a blend of these characteristics would combine to create a nation of serial Rugby World Cup Winners – evolution, eh, Charlie! The Beagle sailed on swiftly, but we will stay a little longer and explore c 200nm of the North Island’s glorious eastern coast, up and down, as ever in our replica Tall Ship Class B.

ORCV Melbourne to Devonport Race 2024

Welcome to the prestigious "Rudder Cup," Australia's oldest and most iconic yacht race, proudly sailed for over 110 years. Spanning 196 nautical miles, this thrilling race takes competitors across the notorious Bass Strait, navigating the unpredictable waters between Melbourne and Tasmania. Organized by the Ocean Racing Club of Victoria, this race is as much about strategy as it is about endurance. This year, our SOLers will be racing in the agile J-122, a 40-foot performance yacht from J-Boats, known for its perfect balance of speed, maneuverability, and resilience. Buckle up for a fierce battle against the elements and each other as we embark on one of the toughest and most storied races in the Southern Hemisphere. Let the adventure begin!

Mistli's Birthday BBQ Race 2024

Welcome to one of Sailonline's great traditions - the generally slightly untimely celebration of SOLer Mistli's birthday on November 1, by way of a tricky race through the Stockholm Archipelago. As always, we are providing you with a fleet of speedy Seacarts to slice through these (at least) 61.5nm of SLI-infested waters, to give you a fair chance that there will still be some beer left by the landlubbers who have descended early to the campfire by the jetty at Trosa!
