Sadly for cheapskate gits like me and I assumed you as you were thinking of importing from USA for cost reasons - who are on a budget (i.e. cannot afford the $300 per seperate chart) then the base map would have to suffice.

Atlantic basemap is the required one.. The detail is the nads but if like me you get the Americas basemap by mistake then USA detail the nads but Europe is absolute shite... Hence why it went back.

Check out e-bay etc for second hand stuff.. Cost down, all the right gear on it etc etc..

And yeah get a plotter - the one I bought and sent back (but will buy again next month) was a Garmin GPS map76s .

Hand held with mounting bracket, internal aerial but with scope for external aerial and power. Smallish screen but kind of the best of all worlds for me who would use it other than on me boat..

I hate to sound too candid on the point but what a bunch of bllcks.

Please try talking to guys on big and small vessels who spend all and every day at sea on commercial applications. What you say is that a standard GPS/plotter is better than a chart plotter. ... why, as you still have to enter your points on both but with the chart you have the background to give you some asuurance.

Many years ago on my deep sea courses I was taught that nav aids are such ie. an aid to navigation. From that I learnt all my celestial nav ( cant remeber much now !) but as any good sailor I would welcome all aids at my disposal.

The diff in cost between GPS cum plotter and gps chart plotter is tiny. Thus I can only guess you are caught in a time warp between pureist celestial nav and 2005 map plotters or are too tight for a couple of hundred .

Above all then if teaching then it must be and to some degree advocate the industry standard.

Cheers

Pookay - do you really mean the basemap? I tried to use it whilst waiting for the BlueChart software to turn up - I don't think you can rely on it to navigate safely.

At one point we were anchored off a beach 6 - 8 metres of water, and the basemap had us a couple of hundred meters inland!! It was equally 'out' the other way on occasion. For the week we were without the BlueCharts we had to use it just as a GPS, because the maps weren't good enough.

The BlueCharts are great though!!

sorry solent ranger, but that, in my humble opinion, is garbage. The reason that commercial and now (finally) military operators use variations on the chartplotter theme is that they present a vast amount of complex data simply and on one easy to view screen. Using one of my (low cost Navman) sets, I can view a whole array of information quickly and without having to refer endlessly to other navigational equipment.

This doesnt mean that I rely soley upon the equipment and in the event of failure we have hard copy back up charts and nav aids (and the ability to use them).

Agree on the price issue in some respects - I installed a C80 display with radar module on my Sealine and all in all it cost over 3k - you live and learn I think is the motto...the Navman on the other hand is about 400 + 150 for Cmap cartridge and is a cracking piece of kit - less time looking at guages and screens and more time at the real world which I think you'd agree is a big plus

In Response to Threads about Overall Usefulness

I've recently invested in a Garmin plotter with Bluechart (CD vesion for a PC, with a download lead and memory card). Previously I'd used a Garmin handheld, which will now become my back-up.

Whilst I support the view that a plotter gives you more options out at sea, better situational awareness etc, the real transformation for me has been at the route planning stage.

What used to take me whole evenings at a time, laboriously marking up paper charts, extracting lat and longs for multiple waypoints, then painfully entering into the hand-held, can now be done in literally minutes with a few mouse clicks, a simple download, and finally a print-off (for 'first-resort' back-up purposes) of the relevant bits. Basically it's put the fun back into it. I can now do most of my pre-planning at work during lunchtimes when it's convenient for me, and I suspect on future dive trips the time saved will occasionally save me from having to turn down the pub trip.

Doing it this way you also get the great 'toy' element of being able to reverse download (back to your PC) the actual tracks followed, and can view these overlaid on the on-screen chart. Great fun! (Might even use these to refine my waypoints).

And the accuracy of the charts I've used appears to have been bang-on so far.

Until recently most authorities were saying electronic charts were not suitable for main navigation etc etc - now I see that the Norwegians are saying PAPER charts aren't suitable as they are too slow to use!!!

This is purely a matter of opinion, and I disagree... I find it easier to read a chartplotter on a rib at anything over 20 knots that even trying to open a chart - never mind cross reference between your GPS and the chart - as well as keep an eye on where you are going....
