    For us geeks, Virtual Spectator does a good job. It was kind of neat to see Movistar and Pirates course change hours before news of the failures was on-line. The first few days the racing appeared very close on the Virtual Spectator display, even though the boats were not in sight of each other on the water.

    ABN AMRO 1 has 242M to go and a 100M lead! Go Stan Honey!

    The old Quakka Sports coverage of a couple of Whitbreads ago was very good. 1000's of virtual skippers were involved and got to test their routing skills against each other and the real boats using real time weather.

    I'd like to see a field limit of say 20 boats, if more than 20 enter, then the top 20 get to race past the first leg (or something along those lines).

    If making the boats a little slower and a little stronger at reduced expense would double the entries I'd consider it an overall gain for the race.

    Yes the Quokka Sports coverage a few races ago was superb- I checked 5-10 times a day online. Now with broadband and sattelite links coverage should be realtime. People I know with only modest interest in racing were watching the coverage then. Now almost nobody I know even remotely cares, myself included- a lifelong racer and nav. arch.

    I know there is a high " trickle down " rate. Look at the complete automation and computerazation of everything, since J F K and his moon race program. -----------------------Tras-oceanic racing is a elitist sport. They do not need anyone. Never have and never will.

    well, it will not be sailing like this that he will win:


    "1306GMT Pirates broach again in the same place and wipe out yet again. Three out of three for them, allowing movistar into second place. Pirates spinnaker flies out from the mast, they are heading for the beach out of control, and have let the sail fly to try to get the boat on its feet and back under control. Ericsson seem to have broken their outhaul and have had to put in the next reef to get any control of the sail. They are lookig for what points they can out of the race. Pirates are still out of control sailing in the wrong direction. …Josse's team gave Team ABN AMRO two places on the podium. Pirates have thrown away a good chance of second place by their inability to get the gybes right and have to settle for fifth…."

    Lorsail, it looks that after all Cayard knows how to sail :D even if that canting keel has made him look dumb:

    "Paul Cayard ...will sail with caution when he leads The Black Pearl into the Southern Ocean next Monday: not due to iceberg fields or strong winds, rather because of the canting keel troubles which ruined his In Port race.

    In breezes up to 40 knots during the In Port race – similar to the conditions they will encounter throughout the 6,100 leg to Melbourne – the Pirates’ stability was compromised by the keel’s failure to swing to windward quickly enough, making a broach inevitable.

    “We will be cautious, but it won’t be with regard to the ice but more to do with the boat and the equipment,” Cayard said. “I was blaming it all on myself that night and then I subsequently found out that our keel canting mechanism is far too slow and that’s why we weren’t able to gybe well that day. It’s not been something we have been able to fix in time for the leg.”

    But Cayard believes the problem, while being dangerous, is not necessarily going to hinder them to a great extent.

    “It’s a bit dangerous not being able to cant your keel quickly and get your stability from one side to the next." ......we can take the spinnaker down to gybe or we can even take the mainsail down to gybe.

    “But I think everybody will be exercising some caution and prudence knowing how fragile they (the boats) are. "
    http://www.volvooceanrace.org/news/article/2005/december/cayardscounselforcaution/index.aspx



    I believe Cayard is wrong. They will sail as fast as they can...till their boats break. Who knows, perhaps one or two can finish the race. That would be about the same percentage as if they were racing with cats:rolleyes:

    i heard something about the Pirates having lighter hydraulic pumps(not rams) which means they are less powerful and consequently cannot tack the keel as quickly as the other boats. Does anyone else have any info on this?

    Scary

    I can't believe Paul would race in the southern ocean with mechanics that don't work right-shivers my timbers.....

    2 more boats down in the Volvo. Anybody know who did the engineering of ABN and ING? Was it done by the designers themselves or was it outsourced to others? Who did the keel hydraulics engineering?

    "...Ericsson stopped racing and turned back with a failure of one keel actuating ram, and then Brasil 1 turned for South Africa with structural failure in the region of the cockpit."

    ............Like the rest of the fleet, both boats were sailing upwind in about 15 knots of wind, making about 11 knots through the water.
    ...........
    In the prevailing sea conditions the motion of the boat through the water would be abrupt and uncomfortable."


    These boats can not stand going to windward, in 15 knots of wind for two days, without breaking?:confused:

    Disgusting.:rolleyes:

    With that added, all of the Farr boats have had to turn around for some reason (although Movistar's damage is not truly the designer's fault) while none of the other boats have had serious damage. Jaun K may not have inspired confidence in the interviews, but I would rather sail in one of his boats than one of the Farr boats.

    Bigger part of us knoiws what is it like to sail upwind in 15-30 knots of wind. Personaly O am sailing in baltic sea, were waves aren't very high, but is very chopy. You have two choises, to slow down or to go banging to every wave, I dont think waht these racers would slow down. These boats are extreamly light and powerful, they are like dakar bugies. Guys onboard ericson and brasil1 ppushed their boat too much, or the boats weren't prepaired enough. Sailing downwind is easier, streses to the boat isn't so great, I think these boats which will make it to the south there the eastern winds are blowing will make it to the finish.

    They are on leg 2 of 9. So far we've had a submerged-object collision, a loose keel, blown bomb doors, many cracked bulkheads, faulty hydraulics, etc, etc, etc. At this rate, I think that making it to Gothenburg intact will be an incredible accomplishment in itself.

    Volvo 70 Canting-Keel Problems

    Sorry if I post something here that has already been covered as I've not been following this subject thread, nor the Volvo race that closely.

    I saw this in Scuttlebutt and thought it was rather interesting...the hydraulic ram materials and the ram interactions.
    _______________________________________
    RAM SHAM AT BOTTOM OF THE WORLD
    The failure rate of the boats in the second leg of the Volvo Ocean Race,
    from Cape Town to Melbourne, has reached an unacceptable level, with two
    boats so badly damaged after three days' racing that they have had to put
    into South African ports while the other five hurtle across the grey
    wastes of the Southern Ocean, clocking off more than 400 miles a day.

    Those who are close to the designers of these boats are critical of the
    relatively short time that the organisers provided between issuing the
    outline rules for the boats and the starting date of the first leg in
    Spain - a matter of 12 months. They say that it did not provide adequate
    time for them to design and test the complex systems demanded in these
    ocean greyhounds.

    Their complaints appear to be confirmed.

    The problem for Ericsson Racing is in a broken hydraulic ram... it is
    exactly the same damage that she suffered in the South Atlantic earlier,
    and on which her shore team spent three intensive weeks of repair and
    reconstruction in Cape Town.

    Russell Bowler, the engineering partner and president of Farr Yacht
    Design, whose firm designed the naval architecture for Ericsson Racing,
    indicates that the demands of the sailors is in some ways compromising the
    engineering of these boats and contributes to their failures. "Hydraulic
    rams," he says, "are in daily use throughout the world in earth-moving
    equipment and there are very few failures there."

    Sailors are not content to use the chromed steel that is the usual
    material for the pistons in the hydraulic equipment and demand lighter
    materials, notably titanium. "It is not simply the difference in the
    metal, but the way that some of these parts are machined," says Bowler,
    "it is that that leaves a lot to be desired."

    Bowler suggests that the double-ram system may well be a contributory
    factor in the failures and suggests that extra time for testing the boats
    may have disclosed this earlier, had the time been available.
