Faulty depth finder attributed to whale attack!!
Booby doesn't count. "Scott Vernon" wrote in message ... There have been numerous whale sightings in 20' of water and within 1 mile of City Island NY. SV "Jeff Morris" jeffmo@NoSpam-sv-lokiDOTcom wrote in message ... These pictures were taken in Stellwagen Bank in about 60 feet of water: http://www.sv-loki.com/whales/ "Simple Simon" wrote in message ... Anybody running a depth sounder in water deep enough for large whales deserves to be attacked. S.Simon "Sidney Greenstreet" wrote in message ink.net... Sydney: Marine electronics technician A.E. Patterson has discovered that the depth finder used aboard a sailboat that was attacked by a whale was faulty and may have provoked the whale into attacking the craft. Marine biologist Ian McDonald said the sounds from the defective transducer mimicked those of a territorial whale. Patterson added the transducer may have given faulty depth readings as well. Yacht skipper Geoff Whitlam said he noticed no malfunction of the unit at all and remarked that at the time of the attack the head was clogged and being unplugged. Tommy Woodcock, aboard and unclogging the head at the time of attack added that the sound of the pumping unit was quite strange as it was filled with toilet paper and a unusually large grogen. "The grogen had fermented for about a day in the escape chute" Woodcock asserted. "Perhaps the aquatic mammal recognized the yacht as a whale giving birth to a mutated offspring and acted accordingly". "Needless to say, it'll be a while before I patronize Rachel Carson's tuck shop, I couldn't stomach strolling about with a trolley load of Aussie pies and vegemide". |

Good memory but that statement does not mean I don't simply
turn the thing off when off-soundings. What's the use of having a depth sounder on when all it shows is no bottom? S.Simon "The Carrolls" wrote in message ... Hay, you said " I don't ;ike to see readings on my depth sounder for extended periods of time,..." I guess you also deserve to be attacked. "Simple Simon" wrote in message ...

Bull****. A chart shows contours, bottom make up such as
rock, sand, shell etc., possible upcoming obstructions and the like. This info is simply not available on a yacht depth sounder. S.Simon - not talking about big ship crap here . . .

And, good morning to you, sir!
With the advent of GPS and its accurate nature, plotting your position on a chart is a more accurate method than using depth readings and dead reckoning. It's that simple. S.Simon "Thom Stewart" wrote in message ... Good Morning Simple, Many of us SAILORS that sail among Whales use charts and depth finders to get a location of exactly where we are on the chart. This is an accepted practest in DED piloting. We finally got a nice cleaning rain last night and we have about 5mph wind at the house here. Waiting for my dog to wake up. We'll probabilly spend the day out on the water. The Pilothouse will come into play. Nice and dry and warm. OT |

A fathometer, be it a recording, digital readout, or blinking light will help give you information to locate that position (personally, prefer the recording). Prior to the advent of all the electronic nav aids, such as LORAN, GPS, fathometers were much more frequently used to check, and even locate, ones position on a chart, be it in shallow or deep water. It's just another tool you have available .... shame you don't understand it's use .... but expected ..... Shen |

Tell that to the crew of the Royal Majesty. They traveled most of the way from Bermuda to
Nantucket unaware that their GPS was not working. In the several hours before they grounded a glance at the depth sounder would have shown that they were dangerously off course. Frankly I was appalled by this incident, since I have never relied souly on GPS, but always verify position with soundings or bearings. http://www.ntsb.gov/publictn/1997/mar9701.pdf -- -jeff "Constant Vigilance!" - Frances W.

A fishfinder gives the info you describe and they're less expensive
than a digital readout depth sounder. "Simple Simon" wrote in message ... Bull****. A chart shows contours, bottom make up such as rock, sand, shell etc., possible upcoming obstructions and the like.

You should not rely on a GPS when using a chart. It's a tool
only. It tells you nothing about your actual position relative to actual obstructions. Charts are notoriously inaccurate and don't match long/lat info. "Simple Simon" wrote in message ...

You're point is not valid for sailors. Only professional motor
boaters carry on in such a stupid fashion. Only sloppy captains like Shen44 and Otnmbrd allow such a slovenly-run ship. Any cruising sailor worth his salt can look into and at the water and tell immediately if he is in shoal water by the color, wave action, shape, etc. Depth sounders are simply not a vital instrument of navigation. I'd be willing to bet more boats go aground while the operator is looking at the instrument than when using visual clues of sea state, color of water, etc. S.Simon "Jeff Morris" jeffmo@NoSpam-sv-lokiDOTcom wrote in message ...

I repeat, WE'RE NOT TALKING BIG SHIP CRAP HERE! Depth sounders give a depth for sure and generally they are pretty accurate. However, what good is a depth when a vessel could be any number of miles along a contour or on a flat? Answer - no good at all. What matters is lat/lon with high degrees of accuracy. Knowing your depth is very vague information at best when attempting to place a fix on a chart. Small sailing yachts can rely on GPS so they do not need depth sounders as much as big ships. When a small sailing yacht is getting into dangerously shallow water the eyes of an experienced will look at the wave action, color of the water etc. and be able to ascertain the depth to a high degree of accuracy. Now, get out of here and go back to rec.boats where you belong. S.Simon "Shen44" wrote in message ... Subject: Faulty depth finder attributed to whale attack!!
