Re: Correcting Charts

I actually found a .05 pen that looks to me like magenta, but colors are sort of the reason I'm not much of a painter, either. I'm not color blind, I just don't care that much about it.

I can see how the magenta matter under red light, so my only idea is to test the pen under red light.

Re: Correcting Charts

As electronics overtook navigation using paper charts, I kept my own set of paper charts aboard deliveries, particiularly south of the border where updated paper charts were difficult to find. I would use my own observations to update charts in and out of Mexican ports where datum info was usually wrong, sometimes significantly.
I recall using a fine black or magenta pens and white-out to correct my older, out of date charts down there. Northern waters it was easy to use Notice to Mariners and updated Pilot editions to stay current. With the almost exclusive use of electronic charts taking over, paper charts are getting a lot more rare... you just need the technical ability to make the updates electronically, something us older guys and gals have difficulty mastering.

All I've seen in a couple years is text descriptions, and callouts of which section of Chart Number One to use.
This is a link to an example of Canadian Hydrographic chart patch.

This is similar to what I get in the Danish Notices to Mariners. Just copy it, enlarge to scale if necessary, print and paste.

Its a set of fine stamps of just about every chart symbol

Occasionally have 2nd Mates asking me to purchase this for the ship, but I tell them if they use a really fine drawing pen, and stay sober, they dont need it.
Good grief, you don't ask for much, do you?

Re: Correcting Charts

Jammer,
I find it amazing how many "cruisers" cannot update their charts since they don't know how to plot a fix without an electronic aid. The best class you can take is the USCG Navigation course offered in all 50 states. I took all of their courses through advanced navigation and found them to be excellent and taught by very competent persons. My instructor was a USN navigator in WWII aboard a battleship. The trick, in my opinion, to updating charts for a cruising sailboat versus a military vessel is to only chart relevant items that would be indispensable to safe navigation: areas of recent shoaling, dumping areas, major changes to buoyage in channels that would not be apparent to an experienced navigator, sunken vessels, etc. But, irrelevant, minor position changes to buoys(of which there are thousands) are a waste of time when they do not alter the general course of a channel but rather are repositioned based upon local changeable conditions. There is no substitute for safe navigation and the best way to safely navigate in coastal areas is to be a competent captain and have the ability to determine your position and course by traditional means: LOP's taken by a hand bearing compass to determine relative positions and fixes and the ability to copy those calculations on a paper chart--whether in navigating or updating your charts. Good luck and good charting.
