Red Eye - Wellington to Nelson 2025


Welcome indeed to our first race of six “Red Eye Specials” - short overnighters through tricky high resolution winds, that will likely have you setting an alarm or two to not miss a weather update or tight rounding or three. This first one is a 105nm IRL classic out into New Zealand’s Cook Strait usually raced around the same time as our online race will start, raced only once before on SOL in 2012, and which on this occasion we will take on in our J-130!

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!

AGage TIMED 100 Race 2025

SOL's gift to the memory of AGagewas a yearlong series of races circumnavigating Australia. This 100 nm race takes place in the St. Vincent Gulf off Adelaide to mark 12 years since the too-sudden end to the life of this remarkable SOLer. These were Aaron's home waters - he was a total competitor so... race to win! Please take the time to read the many tributes left in his memory. This is a TIMED race, so you may RE-REGISTER HERE to 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.
