This year, we’ll proudly share Lake Ontario with the sailing events of the Toronto 2015 Pan Am games taking place concurrently in the Toronto Inner Harbour and just south of the Toronto Islands.

As a result, LO300 Challenge organizers are adjusting the initial part of both courses for 2015, removing Gibraltar as a mark and adding a mark offshore, southeast of the start, to be left to port – and a fresh new angle to think about as you plan your race strategy.

Long Course: Main Duck Island Course is a 300 nautical mile course on Lake Ontario, starting at Port Credit, then on to Mark 1, Ford Shoal Buoy, Main Duck and Yorkshire Islands, Niagara Mark, PCYC Mark and the Finish Mark.


Short Course: Scotch Bonnet Island Course is a 190 nautical mile course starting at Port Credit, then on to Mark 1, Scotch Bonnet Island, Niagara Mark, PCYC Mark and the Finish Mark.


Complete details for both courses and course marks will be available in the Sailing Instructions on the Yacht Scoring Registration and Race Document Web Site by June 30, 2015 and at the Skippers’ Meeting on Friday July 10, 2015.
