This is our 10 year jubileum edition, as it was done for the first time in 2011 (on a slightly different track in year 1).

Jakob's Birthday BBQ Race 2021
Sailonline had two founders and Jakob, the more senior of the two, has his birthday in April and it is therefore fitting that Sailonline's tradition of celebrating this joyous event by racing like loons around the Stockholm Archipelago is upheld. Please join us in a tricky 30nm race in beautiful Linjet33s from Revengegrundet Lighthouse to a birthday BBQ by Baggensfjärden.
Grattis på födelsedagen Jakob!
Lycka till, alla!!

Valletta Sprint 2021
Welcome once again to the Mediterranean and a true SOL perennial. At 588nm in often light Mediterranean airs, to-date no boat – multi or maxi, SOL or IRL – has managed to best the US's Rambler’s time of 47:55:03 for this course set during the 2007 Middle Sea Race. This year, we offer you our Orange 125 catamaran, so the record is on!
