The buoys, they are for moving ….

UPDATE – Change made permanent for the 2014 season.

After many years with the race marks in the same positions, they will be moving as a trial during the Frostbite open series, based on analysis of the wind direction during club racing over the last 2 years. This is an attempt to improve the positioning of the marks to better suit courses that can be set for the predominantly NW / SE winds experienced, but also taking in to account the other wind directions.

The figures below show the distribution of the wind directions experienced during racing on Sundays and Wednesdays since 2012; click on them to enlarge them.

The following figure shows the revised mark positions relative to their current positions; for reference the circles around the new mark positions have a diameter of 60m, or 197 feet for the more mature amongst us. Handy A6 sized reference cards will be available for you to carry in your boats, to help you in remembering the new layout.

If you fancy trying to design courses for these new mark positions or think you can come up with better mark positions to suit the wind stats above,  then you can download an Excel file via the link …. LinkNote: It requires Excel 2010 or later, and the macro’s must be activated.

Feedback will be sought after the Frostbite series is finished, but any comments during the series will be gratefully received.

I started messing about in boats at school, did my National Elementary Dayboat Certificate (a predecessor of the current level 2) in 1980 and have carried on ever since. My first sail at Shotwick Lake was back in '91 and I've been a member for the majority of the years since. My boat owning history is very simple; I don't do "narrow" as testified to by an International Moth, 2 Merlin Rockets and 2 RS300's, all of which are between 6' 7" (2m) & 7' 5" (2.25m) wide! But that said I'll sail almost anything and have in most cases, including the Laser, Laser 2000, Topper, Solo, Wanderer, Albacore, Wayfarer, RS400, RS100, RS700, 59er, Pico, Laser 4000, RS Vareo, Enterprise, Scorpion ..... Racing is very much my thing in all its forms, whether it is around the cans at Shotwick, the Merlin Rocket nationals around Olympic triangle courses with 1 1/2 mile beats, the Lord Birkett on Ullswater (200 boats; 19 miles) or the Round the Isle of Sheppey race (32 miles) with the unique feature of having to capsize the boat to get it under the bridge. I've even managed to fit in team racing in Pico's too! And as I advance in age I've even ventured in to yachting, doing the round the Island race on a couple of occasions. This is an annual race around the Isle of Wight with up to 1,500 yachts of all shapes and size participating.
