And if I recall correctly during the previous (or was it two races ago?) Volvo Race, one boat grounded hard in the Baltics due to some invalid depth measurements (and we are not even talking about “out of the 1st world” area).

Recently the US Navy drove a minesweeper onto a reef for just this reason. Also note the vector chart plotters will lose major details when zoomed out, including entire islands. This resulted in a multiple fatality in California recently.

Many digital charts are based on soundings that may literally be hundreds of years old and would certainly predate GPS. I was in Panama this summer and my Navionics gold charts would have had me drive over a bunch of reefs if I had let them. (I used paper charts from the cruising guide which were spot on) I'm not sure what the chart accuracy is in that part of the world, but if there was any question of dodgy charts, the race committee ought to have given that area a wide berth. It would have been simple to set up a waypoint well offshore in deep water. Putting people at risk that way is irresponsible, imo.

At least that's what the Volvo website alluded to. On Sat, Nov 29, 2014, 12:03 PM Don Newman via CnC-List <cnc-list@cnc-list.com> wrote: They were hit by Cyclone Suzie.

Currently Team Vestas Wind is aground and planning to abandon ship. Is there any reason why a professionally crewed yacht with the latest and greatest nav equipment and shore assistance would come to this? Short of uncharted reefs but that doesn't sound to likely. > I'm curious to know what underwater unknowns you've come across while offshore. > > Cheers > Brent Driedger > 27-5 > Lake Winnipeg > > Sent from my iPhone > _______________________________________________ > This List is provided by the C&C Photo Album > > Email address: > CnC-List@cnc-list.com > To change your list preferences, including unsubscribing -- go bottom of page at: > http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com > _______________________________________________ This List is provided by the C&C Photo Album Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com _______________________________________________ This List is provided by the C&C Photo Album Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com -------------------------------------------------------------------------------- _______________________________________________ This List is provided by the C&C Photo Album Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
