Interesting to note that Slocum disappeared without a trace on his last solo sail. Of course no one will ever know but speculation at the time, based on the voyage planned that would cross busy (at least busy for the time)shipping lanes is that he was run down by a steamer.

Re: Single handing no AIS

My opinion, get an AIS transceiver. Money well spent.

The idea that an AIS transceiver will let people see and avoid you is like relying on a satphone for medical advice.

Are you gonna sue the AIS maker when you get run over?

Please don't single hand and sleep for 2 hours underway.

And for anyone on this thread suggesting this is a good idea - shame on ya!

Re: Single handing no AIS

I agree Dan
The risks to single handed sailing offshore have increased exponentially these days.

Apart from the increase in traffic, with the advent of GPS, the Sea lanes are now much narrower with vessels all following and passing each other within 1nm (mid-ocean).

If I were a solo sailed making an ocean passage...I would first tack way of course of the efficient lanes and would have plotted the intersect lanes from different ports to alert me of high danger areas.

But to be honest...I would not want to solo sail any more...... Too many ships out there now.

Use whatever will aid in your safe passage.
It's easy to avoid ships in San Pablo Bay as they are confined to a narrow channel which is forbidden to smaller boats to enter or cross. Nevertheless, there are 36-knot ferries, tugboats, and pleasure craft on the south side of the channel. Despite the apparent vastness of the bay, I've had to make maneuvers to avoid traffic there. Definitely not some place for the helmsman to take a nap despite the apparent lack of traffic.

Re: Single handing no AIS

The best tools are your eyes and ears. Having said that I think AIS is a very useful tool in coastal cruising where you might encounter some of the big boys or just Tugs and barges. It won't help with the gold chain wearing powerboat owner who sets his autopilot and goes below to watch the game for a few minutes. That said and AIS transceiver will give you and the big boats peace of mind in congested waterways with data that shows that you will or will not collide and whether you need to make a course correction or not well in advance of a close quarters situation. There is enough to worry about when underway and AIS takes away some of that anxiety for both boats that are equipped with it. Then you can concentrate on the others out there who are without it. It's not necessary to have AIS but, it is a helpful tool. I'm glad I have it.

Darn right! It's not uncommon for sailboats to tack or jibe to adjust to an intersectng course toward me even though there is no apparent, legitimate navigational reason (and in this case, perpendicular to the race-course rhumb line.)

Re: Single handing no AIS

I sail my 37' sloop single handed most of the time but only coastal New Zealand to this point. We do have some tricky stretches of water and quite a lot of international and coastal shipping, to say nothing of a significant fishing fleet who tend not to have their AIS switched on to avoid showing the opposition where they are fishing. I have radar which I am slowly getting the hang of and which I have improved by mounting the screen on a hinged bracket so that I can swing it around into the companionway to face the wheel. I have a laptop chartplotter (in addition to the basic Navman plotter that came with the boat) which I can connect (via an HDMI cable) to a TV mounted on the saloon forward bulkhead. This I can also see from the wheel. I have a second VHF radio (with an independent stern rail mounted antenna) which I have had modified to receive AIS signals and which connects to the laptop chartplotter. I also have the Boat Beacon app on my cellphone which allows family to keep track of me on the Marine Traffic website - but it is only good for where there is cell phone coverage! The main benefit I see from being able to receive AIS is in being able to identify and call up a vessel using their name and call sign.

Re: Single handing no AIS

I have never used a ais but surely a radar would be a lot more use it shows everything not just boats with their ais turned on.

Re: Single handing no AIS

AIS gives you a lot more information. In addition to the name and contact details of transmitting vessels, it tells you their course and speed and compares your course with theirs and lets you know if there is potential for collision, and how long before you will collide etc. Even if there is no risk of collision you will be told the closest point of approach to allow you to make a decision about changing course. In my opinion having at least an AIS receiver and radar is a good combination.

+1 to radar!
AIS is pretty much useless if everyone's not using it. True, a lot of good information but usefull only when crossing busy trafic separation lines where it's mandatory. In this side of the pond it means the Channel and Baltic.

Re: Single Handing no AIS

I will always say get one unless your sailing area and style clearly dictate you do not need it!

We have one, we use it, we love it.

Re: Single Handing no AIS

Now that I am calmed down a bit let me apologize if I offended anyone. I believe strongly that soloing in this day and age is an extreme sport, and needs a lot of training before setting sail. Radar and AIS are very useful soloing in my neck of the woods, but most important is lots of prior experience with a group of sailors on a boat in the same waters. I do not believe anyone should just buy a boat and go offshore, no matter what the boat has on it.
