Well said Sir !!
Not-Captain Vigor,
We so enjoyed your dissertation on matters geoidal that for the first time in recent history, we have printed the entire affair onto hard copy so that it might be filed conventionally.
Thanks for the entertainment.

Conventionally Re: Well said Sir !!
Murray,
Filing conventionally? Does that mean you actually put it inside a container? Is the in-box a container? How about the top of your desk?
I am sitting in the midst of five file cabinets and some horizontal surfaces that are covered with things that ought to be tossed or filed. The idea of filing conventionally is foreign to me.
Hope your weekend is going well down under. Spent two glorious weeks there a couple years ago. I gather you are on the south island?

Greaser's Peggy?
I hesitate to inquire as to the meaning of "Greaser's Peggy", lest I be forever branded as one unsavvy in nautical trivia, and possibly keel hauled......
However, my family hails from Bolton, Lancashire, where, according to Monty Python, everyone is DAFT. I am therefore permitted to pose above question without penalty.......

Re: Greaser's Peggy?
John, a greaser's peggy is the lowest form of life aboard a merchant vessel. You probably know that the greasers are the people who squirt oil on the pistons as they they go up and down in the engineroom. Well, I was personal valet to six grubby greasers in the portside watch. I fetched their three meals a day from the tourist-class galley and served them in the greaser's mess, a small metal hovel near the bow. I washed their dishes, changed their sheets and cleaned their toilets. And I locked away the cutlery any time we got near port, because otherwise they'd smuggle it ashore, sell it, and spend the proceeds on booze and wild wimmen.
This was not my chosen career--I was working my way around the world at the time--and I never contemplated keeping it up forever, but it was fun and I got paid a small pittance for doing it, besides saving my fare.
I regret to inform you that several of my greasers were from Lancashire, because this was a British ship, and they were not so much daft as incomprehensible. It was weeks before I could understand what they were saying.
Yrs. humbly,

Re: Conventionally Re: Well said Sir !!
Conventional filing at our place is adding pieces of paper to the pile on the dining table.We have added the greasers peggy description to the heap. We are in Nelson,at the top of the South Island. Had a great winter sail to the Abel Tasman National Park last weekend-a long weekend on account of the Queen celebrating her birthday-the one advantage of being in a Commonwealth country.We have a nice Southerly here today and are going out for a bash around the bay this afternoon,bolstered by a little mulled wine to ward off the cold.Needless to say we shall be using Her Majesty's issue paper charts of the coventional type.In our part of the world these charts use as a datum point, a brass nail hammered into the third pile from the west end of the old wooden jetty at Paekakariki.

Ah, now I understand....
John,
You are correct about the incomprehensibility factor. I best remember my cousin (of the same name, btw) for his quiet mumbling. After some time I realized what it was that he was mumbling on about.....English Football!
I wonder if there is a family connection between your bearing greasers and my relative?
This would make them relative bearing greasers.......

Re: Commander Vigor....more questions???
John,
Received your last Sir, but still have questions, even after consuming many bottles of Port with the Navigator. 1st., what is the datum of WGS84? Is it in fact the Greenwich meridian? I haven't seen it mentioned in any reading I have found on the subject.
2nd., if the chart datum IS WGS 84, and the GPS is set up for WGS 84, would the lat/longs plotted on the chart be close to those indicated by the GPS when you get to that spot? I understand that there may be minor differences, but should be within the accuracy of the GPS, correct?
Okay, finally, Saturday and Sunday last I took Hanalei into Little Naragansett Bay, I marked electronically every bouy going into the channel with a Garmin GPS 48 XL with datum of WGS 84. Actually I did it twice! If you use those Lat/Longs on your personal GPS, won't it take you to the same spots as long as your GPS is set for WGS 84?
Oh, by the way, the bouys were marked as they passed amidships, Port or Starboard of Hanalei, so if you are to the right or left of course, you may run them down!
I posted the info. with Catherine so that she can include it with the Napatree information. Commander, if you are coming into Napatree, try following the referenced positions, and let me know how you make out when you get into Napatree. (If ya don't show up Mate, I think I know what happened, in that case we will have a glass in your memory!)
Oh, and yes I do you use coastal piloting techniques when I get in that close to hazards that are obvious, Log, Lead. and Lookout!!!
Looking forward to a very happy and boisterous randevous, I remain, your most humble servant...

Re: Relative Bearing Greasers???
I can't stop laughing, you guys are a hoot! Oh, John, that hovel at the bow, did you mean to clean the toilet or the HEAD? Just wondering, but on second thought, don't answer that, the web master may object!!!

Re: Commander Vigor....more questions???
Captn. Stump, sir, with respect: By George, I do believe you've got it! Well done, sir! Those bottles of port with your navigator have done your mind a power of good. I must try some this very evening.
Yes, indeed, if the chart datum and the GPS datum are the same, you have nothing to worry about. There will be no differences.
Similarly, as long as every vessel in the flotilla partakes of the WSG 84 waypoints that you, sir, have so have so dilgently acquired, and is equipped with WSG 84 herself, the possibility of mass mayhem is greatly reduced.
Kindly accept my congratulations on this great leap forward in your navigational reasoning. I am greatly impressed. In fact, sirrah, with your permission I shall nominate you for the Brightness in Adversity Award, which, as you know, is given annually to The Most Improved
Captain of a Cape Dory 30 whose initials are DS.
As to your query about the whereabouts of the WGS 84 datum mark, I am obliged to confess that I have no certain knowledge, but from my many dealings with Her Majesty's subjects it would come as no great surprise to me to learn that it was a brass threepenny piece nailed to the desk of the third telescope from the left in Greenwich Observatory, London, across the road from the "Cutty Sark"--which at least would be more visible than the brass nail the New Zealanders use as a datum base in Nelson, according to the latest dispatch from the honorable Murray Glue.
On a point of information, sir--you prefaced one query in your last message with: "Commander, if you are coming to Napatree ..." I am perplexed as to whether you were addressing me or not, since you are aware that I am neither a captain nor a commander. No matter. I am not coming to Napatree, sir. Not because I mistrust your GPS waypoints, but simply because I am currently deployed in Vancouver's territory, the Pacific Northwest, far from the red lights and fleshpots of Napatree. Without those distractions, sir, as you will have noticed, we have time to concentrate on our navigation lessons.
Yrs. in true humility,

There are 106 map datums!!
Just to make everyone feel a little less sure about their GPS coordinates matching whats on a chart listen to this. I have an old Garmin GPS2+ which works just fine. Its default map datum is WGS 84. However the manual states that it can use 106 map datums and it goes on to list them in the instruction book for 4 full pages. They vary in different parts of the world but there are some in the US also. Let's see... I see "Cape Canaveral" covering the Cape and the Bahamas. They have 7 different NAD27 datums ...one for Alaska, another for Canada, still another for the Caribbean. Every country has their own. Including Guadalcanal, Midway Island. I guess you really have to do your chart/GPS homework if you are travelling far and wide on this earth. Just figured we all like to know
