I will continue to share my long-term weather forecasts and medium term routing WPs in this venue.

I ask that other skippers [especially those in the top 25] share similar data.

I truly believe that SOL thrives when SOL skippers have more data.

Pre race stuff...
First order of business is some much needed sleep, missing any wx updates is not allowed in the southern ocean.

Second is to get an idea where the current weather systems are, I am using zygrib and sat images.

Third is to check on previous races, this suggests going NE early on, also a late start may be useful*.

Routing is problematic because BWR cannot handle the dateline. With both sol and zygrib gribs, I have done routes from 'point X' to Cape Horn to get a feel for the race. unfortunately 'point X' is about 36h away from the start, confidence level zero.
Routes to CH will continue thru the entire race.

The coastal part in NZL is mostly ignored except for some rough time estimates. An all-nighter may be necessary :(
Also ignored is whatever happens after CH. This will be addressed with maybe 3-4 days to go.

Beyond that this will be an easy race, just keep up with the low pressure systems, by means of going very fast. Very very very fast. Redshift inducing fast even :)

And that's all. Good night folks.


*data points: last year's Magnus Olsson Tribute, the original VOR stage that Magnus won, leg 5 of the last VOR and leg 5 of SOL's 2011-2012 World Race.

At this point, my route to the Horn looks like this:

Of course, your mileage may vary.

Yes Guys

This one has been a challenge so far. Because of the midnight start here in SA I sat up waiting till midnight....Then had to stay awake to make sure I got away from NZ without beaching. This morning I got an hours sleep and when my alarm went off at 5:40 to get up for work it took my eyes about an hour to stop scratching :)...and today being a workday I see a fading brain happening in my future!

Man I love this pain :)

Now. What to do about the routing. Bluewater is not very helpful yet...Oh, wait, I have a plan...Take the average course being sailed by the top ten boats in the overall race ranking and sail that route. :) LOL. Plan B - Aim for that big purple thing that is going to go screaming past in three days time!

Has anyone noticed how the DTF and ranking appears to be flawed right now? It's almost 1000 miles off for my boat, and I know my current 13th rank is very wrong when comparing actual plotted courses to other boats.

There are several causes for that.

1. The map projection used by the sol client (mercater projection) is distorted near the poles. What looks like the same distance/size is in reality not the same. If you look at the same area of the earth on a globe, you'll see that the boats south are actually closer to Cape Horn than the mercator projection makes you think. Note that this is only visual, the boats don't move unreal because of the mercater projection.

2. The DTF calculation has (or had) trouble with non flat surfaces. Some of the "lines" used in that calculation are Rhumblines (constant compass course, straight on the mercator projection), some are Great Circle lines ("straight" on a globe, shortest distance). This has caused some weird things to happen near the poles in the past. You can read more about this on hmm's blog over here and here.

and of course:
3. DTF is almost always flawed. The shortest way to the finish (DTF) is almost never the fastest way to the finish. So DTF is almost always wrong in predicting who will most likely finish first, or who is leading the fleet.

Most important is that DTF does not matter at all in a race like this.

Current Races:

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!

Andaman Islands PYOC 2025


The Andaman Islands are an archipelago, made up of 200 islands, in the northeastern Indian Ocean. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. These waters will be the theater of our next 240nm race in the ARCH 2025 series. Which one you choose depends only on you, i.e. your Elan 410 sport will leave the Andaman Islands on the starboard or port side.

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!
