SSANZ Race Delta 2021

Welcome back to the Hauraki Gulf and a course that will be familiar to you as it formed the third and final race of this year's SSANZ Triple Series that was unfortunately only raced on the virtual waters as pandemic restrictions in NZ kept racers ashore in reality. With a prudent and careful government, once again, restrictions mean the real racers cannot get back on the water for this Race Delta but, luckily for us, we may well see several of them joining us here to test their navigation skills in our Sun Fast 3300s around this approx. 45nm course.

Gulf Run 2021
It is 550nm on a course of 175 true from Dingle to Vigo, and from Pensacola to Yucatan as well, across the Gulf Stream and The Gulf respectively. It's warmer down in The Gulf, so we return to its azure waters for a re-run in J-130s of a course designed by RainbowChaser back in 2012, but only first run in 2018. Bring your deck chairs and the barrier cream.

Isla del Sol Re-Run 2021
Scanning the globe for special sprint locations, our intrepid course designer Renegade came across Isla del Sol in the middle of the world's highest navigable body of water, Lake Titicaca. We tried to race around it last month, but at 3812m above sea level, comms to our boats broke down for a little while, and our SRC decided to abandon the race, so we are running it again: 26nm RTI in "how-did-we-get-them-here?" Fox 9.50s.

China Coastal Race 2021

Virtual PIC Coastal Classic Yacht Race 2021


Welcome! Kia Ora! to Auckland, New Zealand, and Sailonline's annual multihull race against the NZ Multihull Yacht Club competitors over 118nm from Auckland to Russell. Sadly, COVID19 restrictions mean the real race will not be running, but we welcome real racers to our virtual event where we are racing our 60ft trimarans in this testing event in the endlessly varying conditions off the east coast of North island. As is tradition, a hearty breakfast of bacon butties and rum will welcome yachties on their arrival.
