Race to Up Helly Aa 2025

A-OI!!! The fiery spirit of Shetland’s Up Helly Aa festival is here, and Sailonline’s much-anticipated annual race to Lerwick is back! Spanning 383 nautical miles from Aberdeen, this exhilarating event pays homage to Europe’s largest fire festival. Piloting our Dehler 46s, designed by Judel/Vrolijk in 2015, our SOLers will navigate the challenging waters, competing for glory as flames illuminate the Lerwick skies in celebration.

SAILING NOTE: Gruney may be approached from any direction but must be passed for rounding purposes as indicated on the chart.

Will you master the course, outmaneuver the competition, and claim victory? The challenge is on—join us!

Africa by Sea 2025 - Port Said to Tangier


Back in the 7th C BCE, pharaoh Necho II may have commissioned Phoenician sailors to explore south down the Red Sea and if possible return north via the Straits of Gibraltar. Herodotus was inclined to dismiss the story as it included reports of the sun standing in the north, which had to be nonsense. Silly old Herodotus, but who cares, 2800 years later we will repeat the feat, but we’ll go the other way round, and not in a galley but in different modern sailing yachts, beginning with the comfort of an IY 14.98 for the first leg of 1900nm from Port Said to Tangier.

Aden to Goa 2025


Europeans are primarily acquainted with the historical narrative of how spices reached their continent from distant regions. However, the spice trade from Goa to Aden predates the modern era, as detailed in this article. Sailonline is now reversing this route, organizing an eastbound yacht race of approximately 1700 nautical miles across the Arabian Sea for our 21st-century Archer 78 yachts. Wishing you fair winds and may the enticing aroma of spices guide you safely to your destination!

Vendee Home - Cape Horn to Olon 2025

Welcome to our 2025 Ocean Race Championships starting off with the classic 6900nm drag race from Cape Horn back to the coast of Brittany leading or following the boats of the Vendee Globe fleet. A new polar from the board of the BNH Design Partnership is being made available to you for this one, in the hope that aboard her you too will be able to cover 600nm in a day when the conditions are right! It's winter outside, so like the IRL sailors, enjoy and stay inside!
