I prefer chart Gps and written plan but recent experience in unsettled weather showed chartwork difficult even thuogh reduced and in plastic folders;something like a clip board behind the reduced chart would help.

I am about to buy a new rib and will probably forego a steering compass until next season when I would install a fluxgate/digital reading compass.

Small steering compasses swing so badly that they can "spook" the helmsman;on a recent course in Greece (RIB Int) holding course was one of the hardest aspects for some people who were trying without success to look only at the compass.I find that looking towards a fixed point if available or light or the sun will bring the compass and electronics both into line

'Bitchy' Alan

navigation is extremely simple - You follow the guy in front!

The problem with this theory is:
.... are you a born follower? ... or a leader, see, being a follower, the view never changes!

I personally find............

that being in the middle of the pack gives the best allround view!

Usually end up as tail end charlie sweeping up .. at least on the cruises I have been involved with on the organisation side.

With RB4 we lead Spirit for 8 out of 10 days and then ended up as sweeper for the whole fleet for the remaining two. Actually tell a lie, Bangor Challenger were sweeper for the fleet!

My observations, however from a number of cruises in company are that even the most experienced ribster has to fight the urge to simply follow the leader, or someone else. The true test is when you are sure of your nav but are heading at an increasingly varying course than the rest of the fleet!!

I use a Lowrance LCX 16Ci plotter (GPS/Sonar and I think it might make the tea as well). It's very good but the zoom is pretty slow. I had looked at the Raytheon but found them not as clear in bright sunlight and you couldn't get hold of them.

The Navionics chips are not cheap. I have a medium chart and a small chart on the same chip so that they seamlessly overlap. These cost me 226.78 or roughly $330 US. You get a 8mb chip with the kit when you buy it and I sent it to Navionics and they sent me a 16 mb chip with the charts on it.

It certainly seems reliable and has had a few dunkings in water not to mention the odd hose pipe spray at the end of the day.

I'm happy with it and it was a lot cheaper than the Raytheon.

Hi Nick,
This thread started a year ago, so my posts are old. I now have a Garmin GPSMAP 180, but I'm not satisfied with it. Low display resolution and, more importantly, very slow zooming and panning.
I will probably change it next season and go for the new GPSMAP 182. I would prefer Garmin 2006C, but is way too expensive at the moment.
I think I will stick with Garmin for the time being. Never had any problems whatsoever with my two Garmin receivers. Besides, I really like the new BlueChart cartography - looks great and is cheaper than Navionics and C-Map.

Actualy they do! I have not bought a chart for at least 5 years. I have always found them to be a waste of time in an open boat.For all of our long distance expeditions the passage planning is carried out in the office on the PC and Cmap reader. When I am happy that the passage is correct I study it until it is memorised even if it is for a long trip like the one we have just done,and that is it. This years tour of the eastern seaboard of America before the Atlantic crossing was navigated with 1986 road atlas, the land very rarley moves or changes shape!
The most important thing is when you have made up your mind that you navigation is right, commit your passage to that course. Airline pilots do not use charts and before anyone says "What about depths etc" most instruments have a built in tide table, the display should tell you the depth. Above all, use your eyes, the water will tell you everything that you need to know. Off of Cape Cod in America there is a sand bar that moves anything up to 15 miles each winter, ask the pilot of the QE2, he will tell you that charts are not the B all and end all of navigation.
Cheers and lets hope you dont get lost.

To all

Last year I found a sofware called "Cruising Navigator 4" by Maptech. It 's a cd with all the sea charts of Europe. As far as I understand it can be connected to the ships gps in order to view ones position on the pc display, using the sofware's maps. You may enter waypoints, routes and generally mark just about everything you may need on the map, then save it on your hard drive or print it on your printer. Having used only this product, I am not able to compare it with others (if any) but I sure recommend it.

Well here we have the real beauty of RibNet Forums. As a real beginner, who has never been more than 1 mile offshore, and is never likely to, I can get advice and comment from an old salty seadog with years of experience like Alan Priddy. I must say Alan I was fascinated with your comments on using a road atlas and also about the sand bar that the QE2 has to avoid.

I suppose that the difference is that I don't actualy navigate. I just look where I am going and hope for the best. I love my newly aquired charts and I use them to look at the coastline and decide on places that I can play in my little boat. I look out for any inshore problems such as submerged rocks etc. Of course in the open sea like your Atlantic crossing I can see how a chart would not be much good.

I admire your guts in crossing the Atlantic in an open Rib. I felt excited, and a little frightened, when I got about 1 mile offshore for the first time! I'd love to hear more about how you go about planning such an adventure as yours Alan.

Keith, I know that Alan P. can give you his own answer but I would like to give you a bit more gen. from a slightly diferent angle.
A guy called Andrew Barker has now produced two videos;RIB Cruising and Extreme RIBs. On the second of these Alan P. is interviewed at length about various trips he has made and will be making and the associated risks, challenges etc.
I have got both these videos and can thoroughly recommend them to anyone interested in RIBing. The fact that I received a credit on the video, cause my boat was used in part as a camera platform, has, of course, got nothing to do with my recommendation!
I believe Andrew is now finaling a third video of the RB4 Event.
If you want details of where to get these videos pl. send me an e-mail.

For those of us that have to pay for all their own GPSs AND chart modules the problem is cost. For the RB4 we gave serious consideration to a plotter but the cost of the detailed cmap modules for the whole trip would have been about 1200, So we ended up using two independent handheld type GPSs, both on dash brackets, with a third (borrowed) packed away as a spare. All three were preprogrammed with all the waypoints plus plenty of emergency fall-back places. We then only has to use the charts (colour photocopies onto A4) for "comfort". Once the price of the cartography comes down I'll probably move over..
This "cost" problem is of course not qa problem for "normal" cruising where you only have to buy one chart module for your own local cruising area.
