Apparently AIS & RADAR not Adequate Substitute for Lookout

Rule 5 - Lookout
Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision.

Again, with the elephant in the room. Single-handed cruising (or racing) does not permit compliance with Rule #5. We all gotta sleep.

Herrmann is an idiot:


"At 19:50h UTC this evening, while racing in third place, some 90 miles from the Vendée Globe finish line off Les Sables d’Olonne,"

"he said he was asleep before the collision. He also questioned why his alarms did not alert him to the other vessel, raising the question that perhaps the fishing vessel was not broadcasting AIS."

And arrogant and clueless:

“As if we didn’t have enough stress, this adds to the stress. Half an hour of checking, convincing him. ‘Get out of my way, I’m a sailboat. I have right of way!’ Ha!,” he said, recalling the event."

Seconded.

More Elephants:

“ Rule 5 - Lookout

Autonomous Drone boats, which are out there now fit into this how? And in what way is it different than Boris’ setup?

90 miles has to be only a few hours for these guys.

Let me get some popcorn and a beer. This should get interesting.

Well, I did start a thread on that subject a couple of days ago, but it got lost in the noise.
------------------
So a couple of notices came across my professional desk recently related to the US Navy's MUSV (medium unmanned surface vessel) program and the related DARPA Sea Train program.

Early days, but fascinating stuff. The prototype MUSV - a 195-foot vessel based on existing commercial workboats - is supposed to be at sea in two years - but we all know how government contracting runs. Has to be capable of autonomous operation at sea for 60 days with no human intervention (this is not like most strike drones where a pilot sits remotely but maintains continuous human-in-the-loop control). Prime contractor is L3Harris, who says they already have 115 USVs delivered.

The DARPA program is trying to get the speed and fuel benefits of a longer waterline while being able to split off to multiple MUSVs once the train arrives in theater.

I'm with Snore and Lodesman

Maybe I'm a bit thick but I don't see how having AIS and Radar alarms does not qualify as "a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision." even if you are asleep. If you are in fog, you can be wide awake and still not be able to keep a proper watch.

I would imagine that drone boats are keeping their proper watch 24/7.

Especially with radar, you'd still be keeping a proper watch in fog, just with far less ability to actually see / hear / detect other boats than you'd have in clear conditions.

which is why you are supposed to reduce speed in restricted visibility !

Oh sure, I'm just thinking that these days the AIS and Radar alarms will reliably alert you whether you are awake and busy making coffee or asleep.

Yes, the alarms go a long way. Especially for AIS. But for radar, depending on the situation, you may be able to see / determine more if you're heads-down in the display and possibly making some tuning adjustments compared to just relying on it to acquire a target and alarm based on it.

Ten-ish.
