[QUOTE=NYBoatman;166874]When moving barges around its pretty much impossible to do any plots. Especially since i do all creek work. Take your eyes off the wheel for a second and your up on the rocks or hitting something.[/QUOTE]
Absolutely. I am driving around a one hundred thousand barrel clean oil tug & barge unit out of NY. We pilot, not plot.
On the coast and in the Sound, I will plot on paper in open water too.

This right here. Anything else with our current manning levels isn’t practical or safe.

I don’t think anyone is arguing that navigating in a river or narrow channel using plots on a paper chart is practical.
Kennebec Captain, may I request a link or source for that article please?
Gentlemen,
Thank you all for your replies. I do appreciate your input. Cheers!

Good topic ECDIS, and ECDIS N stands for Navy can lead to new problems. The USS Guardian incident in the Philippines is one. ECDIS is changing from S52 standard to S62, or 64 if forget which. Which means new chart symbols and other changes. ECDIS N has had lots of problems The accident report of the USS Guardian should make a good read. How does your GPS display errors and alarms, When will they standardize this. is the alarm visual or audible, is it still readable if you answer it. Over the years I have seen many variations of this. Yes charts and publication are fun to keep up.

I agree, good topic. Regarding the Guardian, there was some info somewhere… The navigaton team did know and report to the OOD that something was amiss but the warnings were not heeded. ECDIS basically builds a “vitural reality” to coin a phrase in your head which is a very powerful thing. Once a person has built a “mental model” conflicting information can get rejected due to confirmation bias.
The numbers don’t lie, ECDIS leads to fewer groundings, less workload. However when taking and plotting fixes there was a different mindset. When you took a visual bearing with a pelorus or used the Weems speed/distance slide rule you literally “got a feel” for the problem. Also when you plotted the fix often didn’t “cut” perfectly, not all the data matched up perfectly, the good navigator was always on the hunt for a “miss-match” which might have indicated an errror. First being if the fix didn’t fall close to the DR.
That’s why navigation was considered both an art and a science, sometimes considerably experience and judgement was required. No more, now a third mate with the ink still fresh on his license considers himself the equal of Captain Cook.
Agreed. It’s a shame that the Navigator as a position is no longer.

With regards to the ECDIS, increased safety requires the human element gets reduced. The aviation industry is ahead of maritime on this discussion. Here is a good article about Air France Flight 447 by William Langewiesche. Talks about the old “Clipper Skippers” CRM, loss of stick and rudder skills and electronics.
