As promised here is an entry from my 2003 log book. I will post more entries as time goes on. This was a great day as I was able to break the 100 nautical mile mark.

June 26 Departed Pirate Harbour wharf at approximately 10:00 am in light SW wind. I was successful in achieving my goal to complete waypoints from Sand Point to Canso Causeway. Started by beating south to Sand Point and checked various waypoints. Had comfortable wind until I reached the entrance of Bear Cove. Opted to reef main and go under jib and reefed main. Turned out to be a good choice as I hesitated about being too premature. This goes back to the saying that if the skipper is “thinking” about reefing, a reef should be taken in. Was able to reef with no problem as I replaced the original reefing line with the rope from the old main halyard. I am extremely pleased with my single-line reefing system. As winds increased I decided to furl the jib and sail under reefed main alone. Roller furling is a great invention. The wind line appeared to be coming out of Chedabucto Bay and shelter was found in the lee of Eddy Point spit. Decided to stay close to the mainland in order to stay in the lee of any unforeseen wind. This was another good decision as I was able to stay out of the shipping lanes and watch two “Atlantic” tugs escort oil tanker “Nikos L.V.” to Chedabucto Bay.

I think the captains appreciate my radar reflector. I have been told that I show up well on the radar screen. Did some downwind tacking to make a faster passage to Canso Causeway. Repositioned my waypoint for C 28 (Dixon Rock). It appears that my waypoints from Notmar.com are off by an average of 500-600 feet.
Had a brief celebration when Celtic Kiss had reached 100 nm by having a sip of salt water. Thought of anchoring at Martin’s cove for a sandwich but noticed glassy water at Gypsum Mill but opted to beat for Pirate Harbour before the wind dies completely with a flooding tide. This turned out to be an excellent decision as I was becalmed at Cameron’s Point and paddled the remaining few hundred feet to Pirate Harbour Wharf at 1845 hrs.

Daily Distance: 29.00 nm
Distance to Date: 106.97 nm

Wonder what 'datum' you have set up for your GPS.
I use NAD27 as my primary because most of the charts still use it.
I believe it's WBS83 I use as a secondary.

Don;

You're talking WAY over my head. Maybe you can solve my problem though. Can you explain the lingo a bit more please?

I don't have my CPS books here at work but try this http://www.colorado.edu/geography/gcraft/notes/datum/datum_f.html

All I can tell you is that it's a method of reference used by chartmakers.
example...in 1927 someone came up with
NAD27 ...which is North America 1927
If you look in the legend on marine charts
you should see what datum was used.
The NAD27 version is more accurate at the center of the country, but gets a bit 'distorted' way down here. The 1983 versions are more accurate, but the chart makers haven't kept up.
My Magellan 315 GPS lets me choose between a dozen or more different datums.

Thanks for the link. I will look into this and give it some study. In the meantime I wrote into the folks at notmar.com and inquired about the discrepancies I found. Upon closer calculations I note that the buoys are an average of being OFF the charted position by 1/2 nm. The position of one buoy is actually in the middle of the nearby highway.
