Block Island Race - Now Requiring AIS Transponder, Really??

And which crew member was assigned to monitor it?
The crewed boat on starboard saw the port tacker, and thought they had adjusted course so didn't. The double handed boat was on port and presumably didn't see them. They boat that got hit (the crewed one) was hailing, yelling, etc). It's not a mystery how that happened. All the tech in the world won't help one tired person pay attention.

I dont know. Not my boat and I wasnt there. Who was responbsible for one long horn blast and two short ones every two minutes? Or cook breakfast? What does that have to do with the mandate for AIS?

Just that if the boats had been making sound signals then a crew that wasn't actively watching either AIS or radar might have at least heard the signals and been aware that someone was out there earlier. A $1 whistle might have been more effective than a $1000 AIS transponder or a radar in this particular situation.

As for responsible, I'm a Navy man so the standard answer is "the skipper." But they can delegate.

I'm not trying to drag anyone.

AIS gives awareness of general location but it is not meant for collision avoidance. It tells you that something is in the area. If you are pulling a full AIS reading from a service like Marine Traffic then the resolution is improved with last transmitted direction and speed and MT continues to give you an estimated postion based on dead reckoning until the next update. For avoidance you need radar and/or direct eye contact.
AIS -- especially class A is specifically meant for collision avoidance. Class B at the scales of racing boats isn't great for collision avoidance but the whole reason AIS gives CPA and TCPA is core to collision avoidance. But with class B update timings and the case of very congested radio when everyone has AIS transmitters it won't be as useful unless both boats are on a steady course and speed.

True story. In the 2021 B1-2, I was about 100 miles from Newport and I have a LOT of VHF channels on scan. My co-skipper and I sailed past two fishing boats pre-dawn, running lights on, AIS transmitting. We probably passed within 5 miles of them in the dark.

I listened to the guys talking to each other. They started complaining about the new radars they had and how they couldn't see that "f'ing" sailboat that went by, thank god he (I) was running AIS.

My point being that yeah I'd love for the fishermen to be running it too, but they do have receivers and they pay attention to the traffic around them.

That's interesting to hear. I installed a receiver a couple of years back figuring that at least I'd be able to see commercial traffic moving around and was surprised when I sailed up to Maine from Boston and only one fishing boat out of dozens that I passed that night was broadcasting on AIS.

Meanwhile, WTF happened to renting liferafts? I haven't needed one in a while, but I never had issues renting them back in the day.
no need to rent............buy mine ;-) with no more reg for a liferaft on board I dont need mine anymore...Ill stick with AIS............

What about the hand held option? Not a fixed unit but still need to register to your mmsi. 1/3 of the price.

Offshore special regs (2022-2023):
3.29.13:
an AIS Transponder which either:
shares the masthead VHF antenna via a low loss AIS antenna splitter; or has a dedicated AIS antenna not less than 38 cm (15”) in length mounted with its base not less than 3 m (10’) above the Waterline and co-axial feeder cable with not more than 40% power loss

Applies to cat 0, 1, 2, and 3.

Kent Island!
FYI on antennas:
My AIS antenna is on an 8-foot extension mounted at the stern. It meets this rule and the whole setup was cheaper than a splitter. Bonus is if I lose the rig or just the masthead antenna I have another VHF antenna.
For a boat that races more than I do, you may not want the extra windage and stuff in the way.
If I were buying a splitter today, it would be this one:

Pretty sure that unit only receives AIS, not an AIS transponder.

So far the Block Island Race scratch sheet is pretty bleak. I think I'll wait to put more gear on for the moment to see if people decide to come out.

Get the AIS transponder. Single best thing for safety I have bought in ages.
76th ANNUAL BLOCK ISLAND RACE
Friday, May 26, 2023
Notice of Race
Amendment #1 (031423)

1.8 [NP] An operational AIS Transponder shall be carried and be switched on, such that it is receiving and
transmitting throughout the race. The failure of any station to receive a signal from a boat’s AIS
Transponder shall not be subject to protest or grounds for redress (this amends RRS 60.1 and 62.1(a)
and RRS 63.1 shall not apply).
Am I interpreting this correctly as, "You have to have an AIS and it has to be turned on, but there's no consequence for not doing so?"

Don't think so. My take is that there is a consequence for not having a transponder and a consequence for it not being switched on. If the transponder is ineffective, then that has no consequence.

What does your crew say when you tell them you saved money on safety gear that would help protect their lives? Are they proud of your miserly ingenuity?
