2010-08-07 09:54:33 - delayed command
to avoid having trouble with my DC's ı usually give 10-15 min buffer.. however yesterday in auckland race I set DC for 2 hours time with 15 min buffer to tack but again I missed the mark!if it was a dc long time ahead I would think it is whether change but just a 2 hours ahead and my tack point was very cleary after mark!

is there any useful hints somebody can help me?

A CC predictor wanders a little bit timewise but at fixed angle, while a TWA line moves side to side.

15 min is a lot though. If the 2.25h were over an update all bets are off. Not sure when you set the DC but it looks like maybe you were caught by the 2230 Wx?

what I was suprised Trombones was I left on CC so only problem could be wind dropped which was not enough wind for me to reach the mark before my dc! but did nt look like that.. the only problem I can see is my cc was to tight to the mark! so program might shifted my boat to starboat? ı dont know this is possible..

what do you usually do ? when you set dc do you leave the boat in cc ? what is your time buffer?

thnx in advance goblin

If there was an update, a degree or two of shift is enough to throw the (time) prediction out the window, even if the strength is the same.

I don't have a solution for planning across an update. Only real choice for a tight rounding is to wake up for the new weather and then set a DC you can trust, or to wake up for the rounding.

When I know that I'll skip one or more updates, sometimes I've used the shore as an "anchor" to keep a course on target: intentionally letting the boat ground and go TWA0 before the next (CC) DC kicks in. This is the only way that I can think of to know for sure where your boat will be when the DC kicks in, and can help trying to get through a narrow gap on DC. It's not fast of course. Wouldn't have been an option for your case.

Mad Max by Balloon 2026 - Across the Outback


Mad Max Rockatansky doesn’t get to go in a balloon in any of the Legends of the Wasteland, and the Wasteland is not necessarily the Outback of Australia, but Mel Gibson and film director George Miller indubitably are… of Australia, and ballooning as reconnaissance is a main feature of the Mad Max spin-off video game, so here goes: 1500nm in a balloon from somewhere on the edge of the Outback, Goondiwindi, to cross a finish line at Fitzroy Crossing, somewhere on the edge of the Outback!

Cross the Convergence 2026 - Masirah to Chagos


Having crossed, re-crossed and re-re-crossed the Convergence Zones of the Pacific and the Atlantic, we now face our second crossing of the Convergence Zone of the World’s third great equator-spanning sea, the Indian Ocean, taking us from the channel between Masirah Island and the Oman mainland to the Chagos Archipelago. It’s 1900nm and we’ll be sailing our very fine Archer 78, and won’t mention that both locations (of departure and arrival) are heavily militarized and the why’s and what next’s concerning that – mindful as always of SOL Netiquette.
