"head out a coupla hundred metres and mark that spot as the ramp." Now that sounds the thing to do."This will save you ever hitting a marina rockwall or any other structure whilst coming back in the dark at full tilt. Once you hit your mark you'll power off,"Full tilt in the dark to a mark within a few hundred metres of hard stuff? Not sure but that doesn't sound like the thing to do?

If i use the adjustment of .08 southward and 0.08 westward as suggested then i make adg66 191 metres at 218 degrees from the wgs84m position. So why aren't they the same?

Hang on, so if that is what i get then how come Bruce reckons agd66 is 205 metres NE of wgs84 ?? NE is totally in the opposite direction.

DaBilda, Then for Glenelg Dredge i make agd66 205m at 216 degrees from the wgs84 equiv. Is that what you get?

Isn't there a simple black and white answer to this? Which is north-east of what?Who can tell me which way it is?

Now I'm even more confused than ever. So is AGD NE (assume that to be north-east) of WGS or is WGS NE of AGD? A lot of conflict here so which is right?

Thanks now I see what my problem was as I was adjusting these coordinates by 0.08 southward and 0.08 westward as I understood the note to mean and ending up 400 metres out? The adjustment should be around the other way and after reading the note many many times it now says to me this is the adjustment that goes into a GPS set to WGS84 so as to display these coordinates once on the mark.Now isn't this the wrong way around as first the marks have to be input into the GPS to be able to find the marks in the first place.So what is the purpose of this 0.08 southward and 0.08 westward adjustment the

Flicking through that link I see under Outer Harbour the following note[The following locations require WGS 84 Systems to have an ajustment of 0.08 southward and 0.08 westward to agree with AGD 66 points below.]Are the coordinates below this note AGD66? Do I adjust these values by 0.08 southward and 0.08 westward if I am using WGS84?Could somebody please explain what this is trying to say? What should I do to use these values below this note?
