Yes sir! You are correct, it works much better to be able to call the vessel by name. That one feature makes the device very useful all by itself.

When I fly I only listen with a few brain cells to distance or common radio traffic but somehow when my N number is called my ears perk right up. Like when you are called by both your first, middle and last name by any of the woman in your life.

Does anyone know if it is involved to reprogram an AIS to a new vessel?

Thanks John

Depends on the unit. Some older models were completely user programmable. Newer units require a dealer to do the programming. You may find some units no longer supported by the distributing manufacturer. I would start by contacting the manufacturer and have model and serial number available.

That's what side-scan sonar is for.

AIS is a tool that if I deemed it to be economical, I would get it for day to day and would certainly appreciate the security blanket effect in places like Dixon Entrance etc.
AIS is less important in Dixon Entrance but more useful in Narrow Passes. Loran was a Godsend in the day for fishing vessels such as trollers fishing offshore. Tacks were often described by loran lines. It was less useful and less accurate in nearshore or coastal areas.

I upgraded to transceive AIS principally for narrow passages, particularly Active Pass. We are slow and can't "run away" from ferries. We can encounter up to 4 ferries in AP during a single transit. We want then to know who we are and our course and speed. Just the other day we were travelling up the Fraser River and the truck barge Princess Superior contacted us on 16 when they were 2 miles away. We arranged a safe pass on the VTS channel 74.

Yup.

Throw in a few sail boats, fish boats, runabouts, a pod of whales and I don't know how those ferries do it day in and day out. I was in AP on a "Spirit of" recently; dark, dense fog. Knowing we would be meeting another BCF in AP, I went on deck. I didn't see her slide by port to port but heard her.

I don't have SSS. It would be useful when entering poorly charted waters.

So your experience in AP is exactly where you would have benefited from AIS. If I remember correctly, you have a faster vessel than I have and have the power to get out of the way. Our cruise speed is 7.5 kts and we can't speed out of a situation. AIS targets are displayed on our plotter, along with their course and speed vector. That vector is especially important in determining a risk of collision. On Costal Explorer, you can change the forward vector on your vessel, and when you do, all the vectors of AIS targets are also changed. So when transiting in the fog, Pam is standing beside me keeping a watch out the window and I have my eyes on both radar and plotter. And if I have any concern about an oncoming ferry, I contact them immediately by name on the VTS channel and we arrange safe pass. In all instances, they thank me for making contact with them.

Like a licence plate. As for Marin's concern about a snowstorm of boats if AIS is mandatory, well, those bright young folks he works with would soon find the answer to that...If I remember correctly, you have a faster vessel than I...no, I am boatless right now, that's why I am hangin' here asking so many questions...if I have any concern about an oncoming ferry, I contact them immediately by name on the VTS channel and we arrange safe pass. In all instances, they thank me for making contact with them...I do the same thing transiting Vancouver Harbour at night and that's the way it should be. As part timers, we will only gain their respect if we play nicely and like on the roads, far too many don't.

Not using your AIS

...and I would add that proper decorum whilst on the radio is important. All too often we hear people who have no clue how to communicate on the radio. Obviously they haven't taken power squadron's radio operators course, and likely don't have their ROC-M.

I agree and I've been told that, if you think it is bad now, just be glad you weren't around during the huge CB days when they were such a fad.

Tiny piece of trivia for you. In the late 80s the Port Moody Squadron was the first to introduce the radio course as an unofficial part of our CPS Basic Boaters Course. Long time member Alec Smith (later of Pender Harbour) created the course that would become nationally sanctioned.

Ten four that, big buddy.
The overlap of CB-VHF was nuts.

I've had a receiver AIS for about 5 years and our current boat has a Class B transponder. At first it was more of a toy. Once the salmon tenders started carrying transponders, it was a way to avoid gillnets in Prince William Sound, and knowing where the fast ferry Chenega was. Now that we spend 4-5 month a year in SE Alaska, it is getting more like a must have. Anything from, where are the cruise ships, are we really on a collision course, to who is in the anchorage. Two encounters in Grenville channel come to mind. The first was "seeing" the Disney Wonder coming north as we were heading south in rain and fog in the narrowest part of the channel. A quick radio call told him we were going to stay tucked up against the east shore until he passed. The second was almost in the same place a month later heading north. I had no AIS targets indicated but with visibility of only 150 feet I was all over the radar. I detected a target coming south well out in the channel from our track but it would not answer a radio call, until we passed each other. I think our wake woke him up. AIS is good but not the whole answer.

That's where I see them phasing in "mandatory."
Kinda like some highways where snow tires are mandatory in certain areas at certain times...like winter.

Rain and fog is not uncommon on our coast in the middle of summer when the marine traffic is like I5.

I laugh when I hear "What's your 20?" on the VHF and some people still know what it means!

Sorry I missed you. Running late heading South. Definitely enjoyed our evening together in June.

Safe travels!

We are on the Great Loop. The AIS transponder has made life much easier communicating with the tows on the river. There have been times when we are in a group that Fryedaze leads because we can identify the tows by name that are hidden behind the many turns in the river. Having friends with AIS is nice also. You can identify them by name long before you can see them. I can also stalk them on Marine Traffic and set up alerts.
Heres what I don't get. We are always passing half a million dollar + boats that are not transmitting or don't have it.

I still prefer receiving only commercial vessel traffic. Call me a curmudgeon ;-)
Either your AIS is defective, or you have it zoomed out to an unusable level. I'm always surprised at how few recreational boats in the PNW actually have AIS. Never clutters or overcrowds the screen at any usable level.
