2012-04-24 07:09:11 - SWR Leg 6
If you'd like to see some race commentary please reply in this forum. I'm happy to write updates, and I'm sure a few others will chip in. However, it is only worth doing this if there are enough people reading them.

Hi Guys.

I am doing contract work in Harare, Zimbabwe and my internet service is slow causing me to sail using Brainaids Toolbox, Sailplanner and the Miniclient.

Yesterday I thought I would start a tracker on powerpoint to see how the fleet is moving relative to my position.

The attached file is my captures from 10:00 UTC to 22:00 UTC last night and I started again this morning. Visual quality is bad but it makes for interesting viewing when you use the mouse wheel to scroll down the slides.

Enjoy!!

George

I'm going my own way (as usual) up the coast, to try to get a better angle and get as far downwind for the coming transition. High risk strategy but I'm happy with that - someone has to to keep in interesting!

Gybing in 2 hours, will soon change from TWA to CC thereafter

The first day of the SWR leg 6 out of Itajai was quite straightforward. Most headed NE in building pressure. There is little variation in the group and most are in a tight group. Sailing slightly higher meant stronger wind, but at a slower angle and a longer course. As is often the case, those in the best position are in the middle. Late starters had the extra penalty of a deepening wind hole.

Day 2 sees the fleet turning the corner and heading further north. A few more miles east are required to clear Recife, but that is still 1000nm away. The first landmark near Rio has been cleared. Almost all the boats are at least 100nm offshore, but a few have gone close in. There is no current on SOL. IRL that is a factor on this part of the course.

As was described for day 1, the balance is between high and east, or low and west. Turn fast then you head north fast - but is that the fastest way to Recife?

Day 3 sees the fleet sail into a large wind change. The twa trendline curls around to the SE as the wind veers. The forecast is set for 6 hours when a lot of the wind shift has occurred.

I've sailed low into the shift. I was already in an easterly position, and decided to maximise this leverage at the potential cost of some northing. I'll tack on the line of the ruler. Once everyone has tacked, I'll be above the fleet but further south.

Will this tactic work? We'll need to wait and see. There are still over 500nm to Recife but I'll have height and a better twd.

Into the trades we go. These should carry us a long way in fair winds. Gains and losses will become more subtle, but with almost 2 weeks still to sail there are plenty of opportunities to win or lose.

Day 4: The fleet is heading north towards the next mark, Recife, which is the most easterly part of this leg. The fleet has converged as can be seen on the attached plot. There have been small gains by those who have chose the best combination of angle and pressure so far. These small increments have added up to a 2 hour lead over me.

The next couple of days should be straightforward reaching conditions, but wind angles and pressure are still a factor. If the wind veers (turns clockwise on the compass - E to SE) it will favour those on the east; but only if it is a small shift. Larger shifts will mean sailing lower, which is a slower angle than a beam reach.

If the wind backs (E to NE), again it favours those on the right as they have the height advantage already.

Day 5: The fleet is passing the Recife mark, which marks the most easterly point of the course. The wind veered more than previously forecast in the last 24 hours, which meant the boats in the middle gained the most. Those on the right had to sail low and slower or further from the mark. Those on the left either sailed into lighter winds or had to sail higher and therefore slower.

The land and the course head WNW towards Miami after we clear the bulge of Brazil. However, that direction is downwind and would require gybing to stay near the rhumbline. Forecasts indicate that the wind will be E or maybe even NE further north after the doldrums. So it will be worthwhile keeping going on starboard even if it means sailing away from the mark.

Such a course will play havoc with the leaderboard, as those further south will be closer in distance to the next mark, even though they are really behind on the race track. However, those furthest north can take comfort knowing they are ahead even though the leaderboard does not say it. Crossing the line first is what counts most.

New Ice Age 2026 - Scott Base to Neumayer Station


To complete our DN circumnavigation of Antarctica and our 4-race ice-boat marathon series, we continue clockwise, now departing from Scott Base back to Neumayer Station. It’s about 3500nm back as well, which, as said if there’s wind at all, should, well-wrapped in your DN-cockpits, not take you much more than five days. And remember: charts down here are unreliable – what is land and what is ice?!

Cross the Convergence 2026 - Tenerife to Fernando de Noronha


The sixth race of our series of ocean voyages across the World’s convergence zones takes us back up the Atlantic to Tenerife, from whence we will depart on a classic transatlantic passage to Brazil’s Fernando de Noronha. It’s 2150nm as the albatross flies, but you will undoubtedly have to take some and sometimes sudden detours to get your Volvo 70v4 through the doldrums stretching across your path from the Amazon to the Niger.
