Rick - no photos as yet. Not much to take a photo of really, still collecting all the bits and hope to start assembling them later this year. Got some sexy bits though.

I was parked at a small island in the middle of the Tongan group. The GPS said I was a smidgen under 2 miles off the opposite coast so the paperwork was nearly 3 miles out. But then it was last surveyed by Cpt Cook, maybe his GPS was off-line at the time

Twenty feet of variation in the location of a wharf? I have seen charts that note that islands have been seen at separated locations separated by miles in Kiribati- in an area with very low islands and lots of strong, variable currents.

Don't want to be rude but anyone trusting a GPS to 20ft is going to get burnt. Often they are that good but often they are not.

Gord's nicer than I am.

I deleted the original post by Louis Riel, which in my opinion could be viewed as inflammatory. I also deleted those that referred to it.

Thanks for not turning it into a dust-up.

Your action is greatly appreciated

I have found here in Florida, and the Bahamas GPS to be extremely accurate. I check with markers, Wharfs, and have thread the needle in a few places in the Bahamas. I still don't trust the beast though. Like Hud said the old eyeball is very good at keeping you out of trouble. Maybe that's why I have three different lenses on my glasses, because the eyeball is getting OLD quick.....

I finally gave up on relying on my electronic charts when I was going in to Jolly Harbour, Antigua a few years ago. The chartplotter said that the channel marker that was actually right next to my boat was about 1,000 away!

Did you move the channel marker so that it was in the right spot?

**Hud3** · 14-05-2008, 07:51

No, 'cause then I'd have to re-dredge the channel.

I did take a photo of the marker, and of my chartplotter display, and emailed both to CMAP. I was hoping they would update their chart chips with the correct location. They thanked me, and said that their charts were no better than the input data used to create them, some of which is more than 200 years old (British Admiralty charts from the 1700s). I've found problems with the Imray Iolere paper charts of the Lesser Antilles, as well.

A multihull has more stability than a mono and a multi is steady enough my 103 yearold great great great aunt would enjoy walking around on it! HAHAHA.

I took my grandparents on a sail once on an Ericson 35, a somewhat tender monohull. My grandmother was sure she was going to die when it heeled. My comments about ballast didn't reasure her at all. This was a boat that normally sailed to windward with its lee stanchion bases under water. That was her first - and last - sailboat ride.
