I just happen to be about 300 miles from where this incident occured, and my courosity will lead me to check out this "situation" in the next week. But what is this "Pilot line". This us far up in a remote cove, where there are a number of obsticules long before coming to this specific rock. Where was the paper chart? Where was the back up chart plotter on large detail? This area takes great situational awareness--and senses far more than just following a line on the chart plotter. I see this happen all too often. I also agree with Mike about the chart scale, and "accuracy". I am using Garmin Cartography and it shows a different positoin than what the Lady Anne crew gives for the location of the rock. This rock is very clearly marked on the Garmin cartography. Sure I have "bumped" bottom a few times--but to do this damage, I suspect that the boat was going faster than prudent for that specific area and those circumstances. I have explored some uncharted areas in the PNW with my Cal 46--before chart plotters were affordable--and we always went at a speed that no damage was done if we misjudged on depth. Every year we cruise the PNW some boat gets hung up on a rock and substantial damage was done. Some rocks are well known and charted, others are not. Some boats are large (Queen of the North) and some are small. But it always boils down to watching out! There are lots of good lessons for all of us. But studying the charts, doing the homework--not running when tired (this is not a critical pass--it is elective, and if the crew was tired, there were many other locations where anchorage could be taken. I also looked up this anchorage in Donald Douglass's cruising guide to AK. Basically this bay is outside of the permit area for Glacier bay--so no reason to have a time frame to go there -- except perhaps to see the Nordhavn's which were going to cross the N. Pacific... It is an area which was basically uncharted until 2002, and it is known for multiple hazards. Douglass states " You must use extreme caution when entering this Primimative area!" How true! Now I don't have a Sea Ray, or a Willard, but my C Dory 25 is certainly up to checking out this area--and my lead line and hand bearing compass may also be up to the task!
