A crash gybe or tack is probably easier said than done... 
In Response To: Incredible video. This is copy on YouTube which may view better. ()
Hey Steve,
...on such a boat, with a canting keel... Remember, the keel bulb would be positioned way out to windward (to port) at the time of impact.... many are speculating that it was likely one of the daggerboards that actually struck the reef initially...
In addition to increasing the draft dramatically, it likely would have had the immediate effect of laying the boat on its ear, to port - and quite likely resulted in one or more of the guys on deck going overboard, as no one seems to be tethered...
This ain't the kind of sailing you and I do, that's for damn sure...
best regards,
Jon

- Video of Vestas Wind grounding released...
- Watching the beginning a second time, one thing is abundantly clear to me...
- Can't help but wonder what they were "checking out..."
- Incredible video. This is copy on YouTube which may view better.
- A crash gybe or tack is probably easier said than done...
- As I look at it, they were on a port tack
- You can bet the remaining 6 VOR boats are running their depth sounders now...
- What a crash! I'm glad they aren't blaming the zooming red herring.
- Doesn't sound like the issue of Zooming is a red herring, at all...
- His mistake, as he says. He checks on paper as well.
- From the sound of it, he looked at the paper chart before they were rerouted
- Hard to believe any reference to a paper chart was made within hundreds of miles prior to the grounding...
- Insurance probably isn't the issue...
- On my freakin' globe too!
- The owner should receive full value insured. That's what it's for, mistakes in navigation, etc.
- I posted an electronic chart on the other thread
- It's almost a carbon copy of what happened
- His mistake, as he says. He checks on paper as well.
- In a press conference this morning, they admitted the simple failure to zoom in sufficiently was the cause...
- Thanks. I didn't listen to the whole things, but ...
- Using the image you posted, Jon, I have a question
- Can Jon or anyone that has these e-charts, tell me the approximate NM distance across this screen shot?
- I don't have C-map for that part of the world...
- Scale on map you requested, Tom.
- Here's another map, it's a bit older...
- Note the light at the southwest end; and, the notes on "Strong Currents.
- Thanks, but I'm curious, how far out do you need to zoom(NM's of visible chart), when only 40 meter depths show?
- Not a lot -- couple of clicks.
- An illustration of the different levels of zooming...
- The lighthouse specs
- Good e-chart academics but I'd like to see the area on their screens and software.
- Sounds like all of the boats are running a routing program called Expedition...
- Wow! A world of potential distractions, for sure.
- "To win you have to finish"
- Seems like your post poses quite a conundrum for your thesis regarding paper charts
- Don't want to speak for the other Jon, but for me e-charts are far from useless, but OTOH raster are far from outdated.
- Well, I'm not proposing that these racers should be navigating solely using paper charts at all...
- I don't think my point is coming across well
- The Notice of the Race requires all boats to carry the "appropriate" paper charts for each leg...
- The fact that the data is there was necessary, but not sufficient. The boat got ahead of the navigator...

- I don't think my point is coming across well
- Nobody is asking the Volvo boats to plot on paper
- OK, here's an example to try to illustrate my point...

- This latest vid puts a whole new spin on it...

- Another vid, with some different material...
- EAG-Electronically Assisted Grounding-
- Paper vs Electronic
- What's that???
- Correction: Seal and Mud Islands
- I can see that happening. I had to zoom out to 90 NM for those islands to disappear on an ipad.
- At 19 knots, the boat is going through 300 yards in 10 seconds, or so.
- Do you remember the days of, "Oh my god, it's official, I don't know where we are?"
- I remember a few of those times. It was hard over
- I don't think anyone is expecting Volvo racers to plot o paper charts . . .
- I think the navigator(captain) said a last minute change left no time for the usual pre-course strategy?
- That's been debunked, someone over on SA posted a diagram of the original Exclusion Zone prior at the start of Leg 2...

- Sorry, I should have said over 100 yards (316', or so) in 10 seconds
