Brisbane to Keppel Tropical Yacht Race 2025


When the winter weather turns cool in southern Australia sailors head up to the warmer waters of The Great Barrier Reef and the big winter regattas at Hamilton Island, Airlie Beach and Magnetic Island. But the race isn’t ‘on’ this year; nevertheless, Sailonline is inviting all racers from RQYS and beyond to race the 343 nm for the fun, this time in our SOTO 40. It might be winter downunder but do put on your shorts and t-shirts before you sit down behind your devices to get into the spirit of it all!

Haugesund to Reykjavik 2025


In late April 2016 Draken Harald Hårfagre, the worlds largest viking ship built in modern times, left her home port in Haugesund, Norway and sailed off for a challenging voyage across the North Atlantic Ocean.
The aim was to explore and relive one of the most mythological sea voyages – the first transatlantic crossing, and the Viking discovery of the New World, more than a thousand years ago. History tells us about the Viking explorer, Leif Eriksson, who discovered America over 500 years before Christopher Columbus. The expedition was all about exploring the world, just like the Vikings did.
Sailonline is racing the 1000 nm first leg, from Haugesund, Norway, to Reykjavik, Iceland in our Farr 400. Let us sail in the wake of history on this epic adventure!

Africa by Sea - Swakopmund to Maputo 2025


Time again to continue our exploration of Africa by Sea, which now takes us around the tip of the continent at Cape Agulhas and up the coast of South Africa to Mozambique’s marvellous Maputo, where we should find good anchorage in the bend of the Rio Espirito Santo (Umbuluzi) once we’ve cleared the 60m high Maputo - Katembe suspension bridge. It’s 1900nm and we’ll be glad to be sailing our comfortable and sturdy Xp-55, as we will certainly experience more headwinds!

TuziTekwini TIMED Race 2025

Sailonline is delighted to have been invited to partner with the King Shaka Yacht Club (KSYC) of South Africa to bring a virtual version of the Tuzi Tekwini Ocean Raceto our online community.
The Tuzi Tekwini Ocean Race is a near 90 nautical mile race down the east coast of South Africa from the port of Richards Bay to the port of Durban. Achievable in a single day and seen by some as an easy mile-builder, the course is more tactical than some think and should not be underestimated. This iconic race promises to be an unforgettable experience for yachting enthusiasts.
Our online version of the race will be a TIMEDrace so you may RE-REGISTER HEREto try again after finishing a run. You will have 13 days and 11 hours to test your skill and decision making after the race opens.
