Can you enter and exit at an average speed of close to 30 kts (33.8 mph)?

A windsurfer in flat weedy conditions in Australia set a personal best for an 'alpha' - a distance of 500m which includes a full 180 degree turn

Perth windsurfer Mark Woodley made history in Albany on Saturday when he recorded the fastest windsurfing U turn ever recorded by an Australian, and the fourth fastest ever recorded in the GPS Team Challenge, which is a worldwide speedsailing competition for windsurfing. The average speed over Mark's gybe (a down wind U turn) was 29.384 knots, or 54.4 km/hr. The speed measurement is called an alpha, which is the average speed over 500 m including a gybe (a downwind U turn) .

Mark broke his previous record set in 2021 of 28.24 knots (52.3km/hr), and the record of Peter Daish from South Australia in 2022 of 28.8 knots (53.3 km/hr).The top alpha ever recorded in the GPSTC competition is 30.45 kn (56.4 km/hr) recorded by Jacques van der Hout from the Netherlands in 2021. Mark's alpha yesterday is the fourth fastest ever recorded in the competition which has been running since 2007.

Albany turned on sensational conditions for speed sailing on Saturday with a combination of high wind and moderate tide providing flat water and plenty of wind energy for speed. A large group of sailors from Perth, Mandurah, Busselton and Albany and two from the USA made the most of the forecasted conditions with 9 sailors recording peak speeds over 40 knots (74 km/hr) which is considered elite status for speed sailors, and three scoring over 42 knots (77.8km/hr).

Mark is a member of the Perth based windsurfing team the Pinnaroos, who won the annual GPSTC competition nationally in 2019 and were runner's up in 2022 and 2021.
