We make custom laminated charts up from the (Navionics) charts on my Ipad - after saving them as photos I can draw extra information on such as CTS, time to next waypoint, course and distance then print and laminate them - the navigator has to cope with speeds up to 70mph but he does have a 14" widescreen display which can also access the engine data - navigation information is fed to the driver that has a pair of Raymarine ST70 displays and the throttleman has the same as the navigator - an E series 140W - probably a bit much for a small RIB!

Not forgetting a pair of fixed VHF's, AIS etc ..........

Ah actually they sent me a mail with a link this morning and it works fine now, either I was using the wrong section or my account wasn't fully activated!

Glad your sorted. Sorry about this mornings hurried answer but I just never had that problem. No stopping you now. Happy cruising

Chart wise I use admiralty charts as a personal preference. I've found that half an admiralty folio chart is A3 size so I copy, print then laminate on A3. I've done it for A4 sizes but I've found A4 to be a lot less usable.. I tend to keep these charts on the boat unless I'm planning a trip when I'll mark up the charts accordingly.

I've also made up a table template for use when passage planning in case gps signal is lost (and yes it has happened to me on a passage from Eastbourne to burnham on crouch) or if plotter fails etc. I admit I probably go overboard but it has 12 columns (not all are used at each trip) incl

Name of item e.g. NE Maplin
Type e.g. G cone
Characteristics e.g. Fl.g.5s
Waypoint Lat
Waypoint Long
Log miles at waypoint
Dir (M) - course to steer after waypoint
Dist to next waypoint
Current speed
Time to next waypoint
Time waypoint passed

I have the blank template laminated and kept on the boat in case I need it as well as pre-prepared completed sheets (completed when I do my passage planning) which if it is a regular route for me I'll laminate or else print out and keep in a see through sealable plastic wallet. I use Velcro to attach to the console although I guess masking tape would be ok.

When I did my night passage plan for my PB Adv it made it a lot easier.

When it comes to writing on the laminates I've always disliked chinagraph pencils although lots of people swear by them. I use non-permanent OHP pens which once dry are pretty resistant to water and accidental rubbing etc.

That having been said, it's a lot easier using a plotter.

Cheers.

Hence the flipchart idea. I have them arranged so that most trips will be a next / previous page job (advantage of the lochs in scotland - a lot of the water lends itself to a linear map!), so no faffing looking for page 28.....

Different charts for differnet needs. I cannot keep control of anything bigger than A5 without serious risk of it going over the side. (lost 4 event laminates over the years whilst en route to rescue dinghies)
I guess a bigger rib with a big console & a windscreen A4 or even A2 could be easily managable.

Horses for courses!

Have a look on the "falkirk wheel" thread - the reason my plotter is mounted where it is- I spent a couple of weeks destroying cardboard boxes to prototype that pod - it is designed to take my gloved hand resting on the side of the pod while I push the buttons with my thumb. Can easily operate it at 25 knots in a reasonable sea (hand is moving at the same speed & direction as the plotter), and if I need the throttle mid muckabout it's right under my hand.

The trick of driving with one eye ahead & one on the screen took a bit of getting used to.....but when seated the plotter is at the perifery of my vision , so a quick glance is usually enough. If I'm standing I'm reading the water anyway so will stop to check the screen if I need to.

Oh, I don't know. Aim high

Having been on Cookee's boat, the boat itself/engines/electronics/seats/everything else is definitely something to aspire to

I am a Instructor so on my advanced courses I introduce students to most of the methods discussed on this thread and then let them play around with them to see how they work in practise or not as the case maybe.

Below is my own personal "chart table" with a waterproof chart holder which goes everywhere on my RIB and as such has 1000's of miles under its belt - so it does work - very well

Not done Advanced but my instructor on PB2 was keen that I should and provided lots of examples of what I'd learn / have to do.

He didn't mention plotting at high speed but you could expect on the night exercise for them to turn off the chart plotter part way along the journey and tell you its failed and you need to carry on with out it. They might then tell you that there is a problem with the boat or a crew member and you need to urgently head to a safe haven. That safe haven will not be your original planned destination so you need to be able to quickly re-plan your passage from the chart, having taken bearings to fix a possition etc. A well constructed passage plan should have bail out points so it *should* just be a case of taking your possition and working out the bearing to get the to the planned point of entry for the port and then following the previously planned instructions to get into that port...
