RIN Webinar on 'Lessons to be Learnt For Contemporary Digital Navigation

Although I retired as a member of the Royal Institute of Navigation I keep a keen interest in their talks and this looks interesting:

WEBINAR: THE MARINE ACCIDENT INVESTIGATION BRANCH: LESSONS FOR CONTEMPORARY DIGITAL NAVIGATION

 

[jlavery]

Is it open to non members? Hope so!

I registered and I'm not a member

Thank you, I just registered (non member, though I had some sort of login from when they put the electronic navigation booklet online, they required some email at the time).

 

[Sandy]

I am no longer a member and registered for the event.

I see they are running there next Weather and Sailing event in Cowes of all places! It is usually a good day out but why locate it in such a remote, difficult to get to place?

The Marine Accident Investigation Branch: lessons for digital navigation​

 

[justanothersailboat]

Thanks for sharing, Zoidberg! Interesting how many of the accidents rely on a level of complete formal reliance on the system (computer says go... if computer doesn't say go, change settings until computer says go) that I don't think is quite so common with recreational sailing where there's more informal complete reliance on the system (I eyeballed it on screen and it looked like I could get away with it). Somewhat different sorts of danger.

The speech is mostly a catalogue of bad practices in large ships. I found it not hugely insightful. I appreciate that most large ships are safely and responsibly navigated and piloted and that the MAIB disproportionately see the ones that aren't. That said, they can't see all the ones that aren't, and watching this will make me slightly more nervous around large vessels - as it's clear "stay in shallower water the big ships can't go in" is only a safe plan if they don't set up their computers to tell them it's ok to plough straight into those shallows.

I'm registered for and receive the free MAIB Safety Digest quarterly - have done for >decade - and am now mildly surprised by the recurring nature of the causes of the more common 'accidents' they report. There are three sections - Commercial, Fishing and Recreation. I find something to note in every journal.

I never use or store waypoints and use 'go to' in our Raymarine E120 unit/autopilot. I use the cursor as a waypoint and get a course from that.

A fellow Island Packet owner, who shall remain nameless for reasons of severe embarassment locked in a Cardinal Mark as a waypoint.

He hit it very hard, causing severe damage to his lovely boat.

Mark 1 Eyeball and common sense works for me.

 

[zoidberg]

The Mk 1 Eyeball has a lot going for it....

It works in the frequency band ~400nm to ~700nm, which permits far sharper definition than Radar; we each have two of them ( usually ) so comparative motion and ranging is readily sensed; it can discriminate out-of-parallel alignment to ~1/4 degree; and most boats have more than one set capable of deployment.

Best of all, it/they are self-energising, radiate no harmful or detectable emissions, and can be calibrated each season by Vision Express or Glasses Direct at very low cost.
