2009-01-01 18:17:22 - Distance to go to finish and ranking
It seems to me that the distance to go shown is the direct great circle distance from boat to finish. I think this is also used in the ranking - i.e if a boat has less distance to go directly it is ranked better than another even though the other is better placed for following the required route. I think it would be better if you could make the "distance to go" the distance by the shortest route following the required course - the rankings calculated on this basis would then be more accurate. This would also sort the problem where - e.g. in the Hobart to Sydney, the initial rankings were nonsense as we had to go South making the distance to go longer, before it could become shorter.

We actually do exactly what you ask for but in the Hobart-Sydney race we had some other problems leading to incorrect dtg-calcs. Thanks.

Not so much a reply as a further comment. In the current Antwerpen to Belfast, it seems obvious that the ranking is in connection with closeness to the rhumb line, nothing to do with the route we actually have to follow. Could your ranking have been more accurate if you put at least one waypoint of landsend?

Ranking is based on the time sailing. Look at the Leaderboard at www.sailonline.org/board/show/0/

Hi Philip - thanks for that - I had a look as you suggested but do you mean the ranking is based on the most distance travelled per time taken from start for each boat? i.e the average Nautical Miles per hour?

Great Bear Ice Race 2025


You can fly to Great Bear Lake Airport, but if the ice is good, instead hire a pick-up truck, load your disassembled DN into the cargo bed and drive, first following the McKenzie River north, and then straight across the lake to the start of our final Ice Boat series race of roughly 100nm in length. The Airport authorities have agreed to leave all lights on, so you should just about be able to see where you are going as you zing and rumble, PL-free over the ice!

Chile Islands RTI Sprint 2025


Across the Canal Puyuhuapi from Puerto Cines on the Chilean mainland lies the Parque Nacional Isla Magdelena, and further west across the Canal Moraleda from Magdelena lie the islands of the Chonos Archipelago. Returning for the first time since 2017 we find ourselves in vari-charted waters here, with the mapping between physical islands and their names not 1:1 but rather some:some. It’s only 26nm but you could get lost! Good luck.

Christmas to Christmas Island 2025

Two waypoints, start and finish, and between them 5827 NM of two oceans. Not much time if we want to sit at the Christmas Eve table. You will need to maintain an average speed of over 10 knots, maybe quite possible with this Maxi Trimaran, but prepare your vessel well and choose the best of the many possible routes. Hands up everyone who knew there were TWO Christmas Islands?! OK, maybe you have sailed this Sailonline course before... but it's time to get ready for the 2025 challenge of racing between Christmas Island in the Pacific to Christmas Island in the Indian Ocean! It also marks the conclusion of our prestigious Ocean Race Championship 2025. Please have fun! Fair winds!

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
