I guess perhaps to re-word the question, those that have done their Advanced Powerboat, what did you use on the course?

At high speed I sometimes struggle to see the plotter, never mind a chart

Hi

Higher speed navigation does indeed present some challenges re charts.

Ultimately what you use is personal preference but what has worked for me is:

For position fixing at high(er) speed along a coast day/ night I tend to laminate A4 copied charts ensuring there is a compass rose somewhere on that sheet. If needs be I copy a compass rose from elsewhere on the chart into a convenient place so I can use the Bearing/distance to waypoint at compass rose plotting technique. A chinagraph to mark the chart makes it simple.

For entry into/out of a harbour I draw up a pilotage plan on a sheet of A4 and have this with the corresponding chart so it is there if I need it.

In terms of charts I tend to use either the Imray charts or Tough Charts (sadly no longer made) as these survive pretty much anything you throw at them. The imray charts tend to fall apart after a while but then they are not too expensive so I treat them as pretty expendable. If I am using an Imray (larger type) chart I just fold it up into A4 size showing whatever part I want to see (which is probably why my imray charts donít last too long!).

Going back to the self produced A4 laminated charts if you take your time to copy them nicely and laminate them well then you only ever need to do it once for an area as they last for ages.

I tend to agree that operating a plotter at higher speeds in rougher conditions can be quite challenging as your hands never seem to do what you want them to Ė which can actually make it easier to work with a smaller hand held plotter and hand held charts that move as you do.

Regards Paul

I do use a plotter, but as said - a backup plan is always a good thing. I have memory map charts on the PC at home which allow you to print a copy for your own use. I am in the process of (only 'coz I'm doing it on an "as & when" for a new cruising ground) printing & laminating A5 charts, and using stainless key fobs to turn them into a "flipchart" with "next page" references drawn on the sides of each chart print before lamination. It's small enough to bungee to the wheel hub, & doesn't do spinnaker impersonations when the engine is in gear!

Absolutely second the chinagraph pencil - if velcro'ed to the console somewhere can also be used for scribbling down mayday details if you get a non DSC shout.
To me a chart needs to show a big enough area coz otherwise a Rib has crossed the area shown too quickly, and a small chart does not provide sufficient overview. On the other hand details should be shown. To me A5 is showing too little area or/and too little detail.
I am using papercharts for sportsboats fromthr German federal agency for shipping. Their format is A2. I put them individually in the cover they come in (and I have begged together 8 covers), tape the corners and attach them with chock chords to the port side (copilot side) of the console: Click image for larger version

As mentioned before, next page references at the sides make life easier, and for a long voyage they are put on board in the right order. That chart that is of no further use just is put in the jockey. In addition each route is put on A8 (or A7?) wetnotes. The wetnotes have a reference to the chart, and the charts have a reference to the wetnotes for complicated passages. Click image for larger version

HW and LW times are noted on wetnotes for critical points of the route.

And finally, I have a chartplotter. But in difficult and tight passages the plotter is useful for a quick overview only. The routeplanning needs to be done at shore, a chartplotter in 5.4" format is something of limited use at high speed when bouncing around and with cold hands.

Chinagraph (or cheapest eyeliner) +1, and remember to remove notes from gelcoat asap. Needs lotsa elbow grease later if forgotten.

Same issue here...especially in little rougher weather. Using paper charts on the SR is no fun, just having them as backup and route planning even if the coastal charts here are available in pretty handy size. But i take as a routine to drop the speed every now and then, counting passengers and double checking position.

I have laminated all the charts for my area and keep them in a ring binder, being laminated there easy to write on. I also carry 'Sailing Instructions' for my area and 'Welcome Anchorages'. I have a plotter and I have 'Fly to Me app on my iphone. But like others on here I do my plan the night before and write down all my important points and tracks on a seperate paper especially if I am going somewhere new.

I have the Imray charts C1 & C2, but they are too big to laminate, do Imray do smaller versions that can be easily laminated?

Essentially what I was trying to work out is what I needed to practice before doing an Advanced Powerboat course.

I already do a passage plan beforehand, but I thought there was some kind of high speed chart plotting exercise on the course, have I imagined that!

Join My harbour website download using their software and you can zoom in to any location capture and print then laminate, then you will have A4 and you can do them back to back.
