Not for long though, once Galileo comes online. This is the euro system.

Re: Am I over GPS\'d?
I spend all week staring at a computer screens until my eyes water - the last thing I want to do at the weekend 'down the boat' is stare at more flickering digits..!
There, I've said it.

Re: Space onboard
OTOH, in the Clipper race (2000 edition) the yachts had to divert to an unscheduled port. The race office emailed them unlock codes for their Seapro charts, and lo! They had charts for somewhere they didnt have paper charts for.
Nothwithstanding that, I would always carry paper charts, and pilot books (and preferrably two in order to get a different point of view), despite the fact I am amongst the most electronic oriented person. I do normally keep a log (except when I am laid out by food poisoning), but also like the fact that my Navtex receiver prints out lat and long every 15 minutes, so if all power goes I have a starting point. Oh - and I also carry a Walker log, lead line and a spare GPS or two.

I\'m afraid I don\'t understand
the rationale behind your question.
However many GPS you have, without a chart (paper or electronic) they're quite useless. All they will give you (in my experience) are a number of comflicting positions to 3 decimals of minutes with no relation to the part of the earth's surface you may be.
Perhaps you may care to rephrase it in such a manner that a bear of little brain, such as I, can understand the point you're getting at

Re: Am I over GPS\'d?
On a visit aboard HMS Scott (RN oceanic survey ship) a few years ago they were convinced that they would navigate using paper charts for at least the next 30 years, and use the electronics as backup!
Have we joined the euro, then?

Re: Am I over GPS\'d?
"One point which seems to have been overlooked here and that is all your GPS receivers get their information from ONE source, which is bad practice"
no they dont. one satellite cant give you a fix. my gps usually looks at 6, and they are all independantly powered etc.
but in any case, how far do you carry this redundancy idea? monohulls can sink, so should you always sail a catamaran - if one hull fails the other might still be ok?
and how many engines. in the light of the comments on these forums, engines are a bigger source of problem than almost anything else.

Re: Am I over GPS\'d?
What troubles me is why you could possibly want to use that lot, let alone buy it in the first place.
First you 80110X up the balance of payments defecit by buying all that imported electronic stuff, then deprive our Hydrographic Office of all that luverly income by not spending enough on charts.
I so hate programing my GPS with waypoints I only do it if short handed / going in heavy weather / anticipating a challenging time, so it can beep at me at the appropriate time.
Giving me a bearing and distance from the rose on the chart is about what it's best at.
Tried switching it all off lately and just enjoying the sail and the challenge of making the landfall you intended?

Re: Yes. Overboated
Meaning your boat is big. The handheld GPS's must be for new crew members to find their way around within.
Asterie is quite lovely.

OK Hands up!
Hands up indeed. It only struck me on Saturday when we all sat there with a beer just how many GPS's I've ended up with. I've only bought one hand held the rest have just been inhereted.. It seemed like a good idea for a post..
I still use charts, pencils, rubbers a hand bearing compass and a Breton plotter...and do a passage plan.
They are a nice to have, the PC is deadly acurate linked to the GPS with C-map. (Duncan found it upside down though, tee hee, sorry mate I did promise not to tell). I've not tried the prettier Admiralty jobbies yet..

Re: Am I over GPS\'d?
The one source to which I referred was one group of satellites, and I venture to suggest that no matter how many receivers you have on a boat they will all use the same group. The second source should be one different from satellites.

Re: satellites
When Galileo is up and running won't there be two sets of satellites?

Re: OK Hands up!
more 'the other way up from mine' than upside down!
having come from a multi plotter environment (my helm) to Asterie my initial reaction was that you had the right tools for the job taking into account an autopilot - ie you could always put the boat on AP and then utilise the chartable and PC / charts for navigation and, whilst helming you had the compass and HH GPS for nav screen to waypoint (programed from charts etc as required).
I did think you cold have benefitted from a nice plotter unit handy to the helm but quickly realised that (1) you didn't need it 'cos you could leave the helm (I don't have an autopilot and wouldn't leave the helm at 30 knots anyway even if I had!) and (2) some silly sod would bash in to it or grab it underway.
