AIS vessel type?

[vyv_cox]

I have bought an AIS transponder and am in the process of setting it up. I have two options on vessel type: 36 - sailing vessel or 37 - pleasure craft, that does include yachts according to various internet sites but to some people this might include 60 ft mobos. Is a 10.6 metre sailing boat a sailing vessel or a pleasure craft?

I went for sailing vessel so not to confuse "stand on" colregs as such.

 

[awol]

I claim "sailing vessel" in the forlorn hope that I may be given the precedence that the label should give. I may be fooling myself but I like to believe I am more often under sail than motor.

I also went for "sailing vessel" for the same reason. It's never a disadvantage but might be an advantage.

If I had a transceiver, I'd choose "sailing vessel", hoping that shipping would give me sympathetic consideration.

 

[vyv_cox]

Thanks all, that was my thinking too. It defaulted to 37 but I suppose the supplier does not know who is buying it.

Doubly confusing because I suspect lots of owners consider that it is only a pleasure craft when actually sailing!

Sailing vessel here.

Doesn't it rather depend on what you do when you're onboard

 

[Uricanejack]

I would choose pleasure craft if it’s a set up option. Which is not easy to change when in use. The ambiguity left leaves room for me to sail or motor.
If I choose sailing vessel as the set up I would be possibly be misleading the recipient to the AIS signal. When I chose to motor rather than sail. Particularly since the difference is significant.

If it’s easy to change under way choose between pleasure vessel and sailing vessel as it best fits your description at the time.

Whatever fits the bill for you
36 Sailing Vessel - Sailing Vessel
37 Pleasure Craft
- Yacht
- Museum Ship
- Exhibition Ship
- Floating Hotel/Restaurant
- Theatre Vessel

Surely no-one is going to think that a "sailing vessel" can only be wind-powered and hence might be misled by a yacht going at a similar speed but under power?

Exactly. Under some conditions my sailing speed is far greater than my motoring speed anyway. Sailing vessel seems far more appropriate than the bundle of possibilities shown in post #11, which I had also found.

I've taken the view the maximum speed over ground I've done, tide assisted, was 10 knots and we usually have the main up even under motor so it has to be Sailing Vessel.

It's usually only the MMSI which is tricky to change. Everything else is just a matter of firing up the configuration app/program on the tablet/PC. However, I would never want to start changing the data depending on what the boat was doing as I'm far too relaxed. Hic.

In a recent (Jan 2019?) PBO article, the author selected 37 because that's the USCG recommendation (I think that's what the article said; it seems implausible now!). Not a powerful motivation but if there's no other guidance ...

 

[Uricanejack]

I haven’t read PBO recently. However it does make sense to choose 37 pleasure vessel. Which leaves it open.
I don’t have an AIS so I dont know the list of options. Presumably power driven vessel isn’t one of them.
Certainly if the I or information part of AIS is to leave you guessing then it appears the system isn’t achieving it’s supposed intended purpose.

So would I be able to figure out the “ Sailing Vessel” doing 6 or 7 knots with no wind or into the wind is not actually a sailing vessel. In fact just a door knob in a power driven vessel, with a sail up, no cone, the wrong lights and shouldn’t be surprised the same door knob has his boat identified by AIS as a “Sailing Vessel”.

And act accordingly. Now I am making an assumption the sailing vessel isn’t a sailing vessel. Am I the give way vessel to the approaching sailing vessel on my port side or am I the stand on vessel for the approaching power driven vessel on my port side.
Are you going to be pissed off when I decide to turn to port and go round your stern. Or should I be standing on on the assumption you are going to act like a power driven vessel, because any one should be able to figure it out.

Perhaps it’s better you don’t transmit, but stick to receive only if you are not going to bother providing the correct information.

To my simple brain sailing vessel applies when actually sailing, same with fishing vessel though expecting fishing vessels to show the correct lights or shapes when they are not fishing is a forlorn hope.

All of the above leads me to believe there was a very good reason that they called it AIS - an 'I' for 'identification' - rather than ACAS.... with 'CA' for 'collision avoidance'.

For collision avoidance purposes surely other vessels will be basing their actions on either your lights or daymark - if shown.

In fog its a whole new game ..... Rule 19 makes no mention of sailing vessels or pleasure vessels.

Unless you want to be forever changing your class I would go for 'pleasure vessel'.

+1 Well said. Change your vessel type as often as you like but what are you going to do with your class B transmissions when at anchor? I would expect a watch keeper to know that virtually all sailing vessels have auxilliary engines.

 

[GHA]

Class B leisure users are advised that they have two suitable options for type of vessel, ‘Yacht’ or ‘Pleasure Craft’. To assist in deciding which to use the following definitions should be used:? Use Yacht (36) for a vessel where the primary means of propulsion is by Sail.
? Use ‘Pleasure Craft’ (37) for any other means of propulsion.

(yacht{36} should be sailing vessel?)
