While GPS displays will never be as large as the charts used on the Yeoman, I think GPS Nav-programs made the plotter-boards obsolete a long time ago. It might still appeal to anyone who appreciates being able to work on a chart, having most of the tools of a nav-system available at the board versus changing miniature GPS display screens all the time ;-) Jack Painter Virginia Beach, Virginia |

It is stiil a great tool and mapmakers do not like it.

: Has anyone used a yeoman plotter? what are they like? are they worth having? Bobby My captain had the foam portable version and left it in the hot Atlanta sun in his pickup truck, where it promptly melted all the hotglue it was put together with. He asked me what I thought we ought to do with it. (He had in mind junking it, the silly boy).... I took the scanning board out of it and used industrial-strength (5 pounds per foot) double sided foam tape and made 3 long strips as wide as the board in the Yeoman was on the side of the board opposite the computer daughterboard mounting. I stuck the Yeoman to the bottom of Lionheart's mahogany chart table top close to the edge. There's a bottom and right- side fiddle on the table top that makes a great index to hold the chart book to for use with the Yeoman. The puck simply comes out on the left bottom corner from under the top. Yeoman is connected to the boat's NMEA bus so it gets whatever data is currently in use. The signal through the 1/2" thick mahogany top is plenty strong to go all the way through a folded back chart book and about 3/4" above the surface of the chart on the other side. Pull the whole book hard against the fiddle and calibrate the three points on the book already memorized (Maptech charts) and she's ready for paper backup navigation the easy way. Every hour we mark the chart and plot the course on the plastic overlay under the watchful eye of the Yeoman. What a waste it would have been to toss it..... |

news:U1fBe.13258$HV1.495@fed1read07: What is a yeoman plotter? It's a scanned piece of PC board (usually mounted in either a foam holder in the portable model, or attached to the bottom of a chart table top in permanent installations. The scanning produces a magnetic signal that scans across the board in lines, then down the board, much like the scanning your television does to make a picture. The pickup for this signal is a "puck", just like the ones used for electronic drafting tables, but with buttons specialized for navigation. The computer that generates the signals also reads the data from the puck's electronics. By comparing the two signals, the Yeoman's computer knows within a pencil lead thickness where the puck's pickup coil center is in relation to the scanning board whenever the puck is near the board...within about 6 inches on ours. Now, programmed into the permanent memory of the computer, are reference points that match the Yeoman reference points on Maptech's chart books. Each chart page in each volume has 3 reference points that make a right angle. You select the volume number, then page number on the puck's LCD display. Then, you put the chart book on top of the scanning board so it can't move and screw up the calibration. (We put it against two fiddles on our chart table which give it the reference place.) Now you point the puck's little target hole over each (marked A, B and C) and press the enter button as the LCD asks you to show it A, B and C points on the chart. As soon as you enter the points, the display switches to Lat/Long and starts reading the exact latitude and longitude, nicely calibrated to the chart. As you move the puck over the surface of the chart, the display shows the puck's target position in Lat/Long on the LCD display. If you chose not to use the Maptech charts, ANY chart in ANY scale will work. YOU put 3 reference points on your chart, two on a line of latitude and one on a line of longitude common with one of the latitude points making a right angle. YOU tell the Yeoman puck the lat/long of each point you chose on your chart and it stores this data for future use in its user memory bank. All you do is make a notation on the paper chart of each point (mark them A, B and C) and make a note in the margin of the chart as to which user memory this particular chart's data is programmed into so you can easily recall it later. Do three points on all your charts and you can use them all with the Yeoman, any place on the planet. It even works on common aeronautical charts, if you like. Around the target area are four LED lights that make arrows away from the target. These arrows tell you which direction to move the puck to put it over your present position, unless you've clicked a specific point for a waypoint, for instance, then it shows you the way back to that point. When you get over your GPS' current position, the arrows all go out, easily showing you your exact position (within the width of a pencil point) on the chart....no drafting by hand to do. To plot your course on the paper chart, simply move the puck until the arrows go out and mark your position with a pencil through the puck's target hole made for this purpose. There's another little handy button on the puck that changes the display from Lat/Long to azimuth and distance. When you click the button, the display shows you how far you are from either your current position or from a reference point you've clicked up. "How far are we from the harbor entrance bouy?", you ask. Click this button and simply put the puck target over the bouy on the chart. Read the course and distance right off the LCD display on the puck. It's that simple. Yeoman will also transmit to your NMEA network, too. Lionheart has two chart plotters at the helm, a Raymarine RL-70CRC radar/chart plotter display and an old trusty Garmin 185 chart plotter/sonar. She also uses a Dell Latitude notebook running The Cap'n nav software, which IS her primary navigation system. Because the Yeoman's data output is connected to a port on our NMEA network multiplexer, the network is fed NMEA data from the Yeoman, like waypoints near that bouy if you like. When you click up a new waypoint on the Yeoman, it shows up on all the other charts in the system. We don't use the Yeoman for this because of the computer charts being much more comprehensive, but it's a great backup system. Aboard Lionheart, Yeoman provides us with hard copy course plotting every hour just in case the whole electronic suite goes down. The line we keep on a plastic overlay on the paper chart insures we know where we are if the whole boat's dead. In a simple system, a GPS receiver, even a handheld with data output, and the Yeoman plotter will give you great navigation without all the old mechanical measurement problems rocking about.... Works great.....easy to use. http://www.yeomanuk.co.uk/ http://www.marinews.com/electronics/electronics/GPS's/e_silvagps.htm http://www.yeoman.net/ B&G bought Yeoman: "Central to establishing Precision Navigation has been the acquisition from Brookes & Gatehouse, of the manufacturing, marketing and distribution rights of the Yeoman Plotter - which both men feel is a hugely underrated piece of marine navigation technology. Cole commented, "The Yeoman plotter already has thousands of dedicated users throughout the world. It has a unique place on the navigators chart table either as a stand-alone plotter or as a compliment to even the most sophisticated navigation package."

Thanks. While it sounds good, it seems that the only advantage is that of
being able to make DR plots on paper - chartplotters do everything else, and maybe more, than Yeoman. Right? "Larry" wrote in message ...

Correct, but you are working directly on a full-size chart with Yeoman, no zooming, no panning. Having used one, I prefer the laptop, but Yeoman has it's followers who won't use anything else.. |

Yeoman's don't draw on the paper. The Yeoman will store 1000 waypoints and 1000 routes, etc., just like plotters do.

: Having used one, I prefer the laptop, but Yeoman has it's followers who won't use anything else.. We use The Cap'n on the notebook for main navigation and planning. The Yeoman was "saved" by me from the dumpster. My captain left it in his pickup truck in Atlanta in August and melted all the hotglue from the Sport XL. It was a real mess. I saved the electronics out of it and junked the foam pad. I cleaned the glue off with acetone then attached the big PC board (and the daughter board with its main computer on it) to the bottom of Amel's mahogany chart table lid. It was a near perfect fit. I used 50#/inch double sided industrial tape...two full-length strips. The puck cable just comes out the space where the lid meets the bottom when the Yeoman is in use. The puck stores inside, wire and all, when not in use. You'd never know looking at the chart table the Yeoman even existed unless you open the table lid and see the electronics under it. The Yeoman's signal has no trouble at all reaching through a half inch of mahogany and the whole Maptech chart book folded up so the chart we want is on top against the fiddles. On the chart, we lay a clear plastic sheet for drawing on with a marker. No chart book to clean off.... The puck on top of the plastic sheet works really great. -- Larry This jerk called my cellphone and was nasty.
