Secrets of Raymarine

You can also use the MARPA thing by backing off (widening the view) until you can see the big ships moving fast, then clicking on them to let MARPA track them. It will give you a flag with their speed and direction over 20 miles away. Of course the protected area for the emergency alarm warning just mentioned is nice too. After setting these, you can focus back down onto your smaller immediate area.

I like to search wide for potential problem craft, mark them for tracking with MARPA, and then I know what possible problems could arise far in advance of the actual warning zone.

From personal experience, I can highly recommend Raymarine's AIS Receiver. It shows you very clearly where all the commercial traffic is around you.

Just in case anyone else has had the same problems I had at the outset of using my E-80 units, here is an odd problem and fix that are not in the book.

My boat icon's orientation was not representative of my boat's orientation, i.e., the icon did not point the same way as the boat was pointed.

My electronic's installer up in Edmonds repeated the circling and setup procedures many times. My unit would also just go "out" periodically, usually when the seas were the roughest. A local tech in Oklahoma finally found part of the problem - the installer had grounded the Seatalk cable lines. Seatalk, he said, is basically like speaker wires - no ground.

I still could not get the orientation squared away, so most of the E-80 options were not available. Not until I had purchased a set of binoculars with digital compass down in Galveston, TX. I took the bearing from those binoculars pointed straight ahead (against the center window frame) and MANUALLY entered the boat's orientation.

Finally, all the E-80 functions began to work properly. I could finally use all of the format options. I could use the green and red arrows showing boat heading and true progress, etc.. The long green arrow of true progress prediction is invaluable in making certain you are really travelling to the desired location, since the direction the boat is pointed is often not the direction of actual travel.

So, if problems, try manually setting the boat's position and manually setting the deviation for your area. It rounds off to a degree anyway, so those circling setup maneuvers are not necessary if you have the info on a map or binocular compass.

Hey Thomas,

For me it 's a good point and bares repeating. Idea

BTW, I really enjoy your expertise on the Raymarine thread too.

Does anyone know how to change the color of either the range rings or the other data, numbers, etc. on a C-80 when in the chart screen? I like the range rings but often cannot find the actual range ring "range", i.e. 1/4nm, 1/2nm, etc. The numbers and lines are all black and the range ring data gets lost in all the other stuff. (of course it would help if the range ring ranges were always in one location, mine appear anywhere on the ring depending on the scale I'm using.

Thanks.

Does anyone know how to remove or radically scale back the vector arrow on the chartplotter? I know I can adjust it to 3 minutes, 6 minutes or Infinite, but all of those have the unfortunate tendency to obscure little things dead ahead like rocks and shoals and who knows what else?

Thanks,
Warren

Gang... Going on my first 180-200 mile 3 day river trip with my new e80 raymaring. I have done a cut-n-paste of each of these post...minus one or two that was just sweet mutterings we all do... and put them on a microsoft word file.

I have not cleaned it up at all...just needed to print it fast to take with me and Jeff Brigner from C-Pearl on our Cumberland River Run..

Thanks..I know I will need some of this stuff from REAL USERS...

Byrdman.... on da rivva..

Warren,

The WIDTH of the vector arrow is related to the STRENGTH (FLOW) of the tide. Go to the bottom of the screen and turn off the TIDE/WIND arrow. Then you should be left with the thin red and green arrows: red showing which way the boat is pointed and green showing true direction of travel with the length of the green related to your speed. I had this same problem in Galveston with the fat tide arrow obscuring the area right in front of the boat!

Warren,

If, as I think you are asking about the bearing line, not the current/tide indicators. The bearing line width can be adjusted at the same location where you can change it to 3 minutes, 6 minutes, etc. There is a "wide", "Normal?", and "narrow" setting. The narrow setting is quite thin and unobtrusive.

I found out from Raymarine that it is not possible to change the color of the range rings and range data. Oh well.

Colobear,

When you have the tide/wind indicator activated, it makes the arrow grow and wane with the tide. Inactivating that function made my direction arrows go back to the minimum.

This is a great thread. This is the SORT of information one hopes to find over at http://raymarineforum.com/, but that site hasn't really taken off so far.

John,

Maybe I'm confused (Yes I know Laughing

thats my normal state!) but what I am referring to is the green bearing line that emanates from the front of the boat symbol on the chart screen. I can't recall that ever changing whether the tide/current automation is on or off. I'll have to take another look.
