Still not what we saw.
And trying to offer a slow pass to sailor and slower trawlers was mostly a crap shoot.... especially when we couldn't see (or read) a boat name... what with radios off, or maybe down below, or maybe no radio watch...
Plus fancy fonts on the quarters (instead of stern) are mostly useless for figuring out boat names...
By slow pass... I could clarify. We often travel at about 8-8.5 kts, at least when sea states permit. We often encountered boats going slower. It's usually easy enough to get by without rocking their boat, but I do still like to offer a slow pass just in case somebody happens to be listening. Often the answer to that has been "not."

I'd rather have the Navionics app on my phone. The jetties and channel don't move.

But how well is it charted? I’ve had chartplotters and iPad apps that show my boat on land when very clearly I’m moving through the water!
Some channels do move, but I wouldn’t consider those as being very safe for nighttime navigation, unless CG is on top of repositioning the markers.

Re: Radar or AIS to rouse me when in a stupor?
As an interesting side note with absolutely no point to make:
I recently did the shifty Big Sarasota pass inlet by gps waypoints alone. No local knowledge other than the waypoints
Another first for me. It was a little nerve wracking. Was thankful it was daytime so i could see the sandbars all around me. Made me feel better even if I didn’t use visual cues for navigation.

Brave man…..but what’s your draft boards up?

I had boards partially down and rudders down and out boards down.
I think I was drawing approximately 3.25 feet.
I’m only 24 inches if I pull everything up. But the boat does not work well without a little bit of dagger board. Too much sides slipping.

Re: Radar or AIS to rouse me when in a stupor?
One thought? Get neither.....cuz that will keep you more alert then if you begin to psychologically rely on a proximity alarm. (I helped a friend sail a boat from San Francisco to Cabo. When I learned he had no radar, I was nervous. 1,500 miles later, I learned to trust my eyes, binoculars, and charts. And I came to realize that while I was exhausted, I was definitely more alert and confident on the overnight shift. That said, we never hit much fog or poor visibility conditions. That might have changed my perspective!). Best of luck, whatever you choose...

If you helped a friend sail to Cabo, there were at least two of you onboard. That is not singlehanding which the thread is about. You could get sleep/cook/crap while another pair of eyeballs was/could be on deck.

Exactly.
you get the spirit of this thread. You have to be able to eat. You have to be able to use the bathroom. I want another mechanical pair of eyes for these moments. Even if I start nodding off on an overnight.
Alertness can drop single-handing. Might as well have all the tools you can to help with that.

Re: Radar or AIS to rouse me when in a stupor?
Alertness does drop singlehanding. I basically sailed from Los Angeles to Cabo then La Paz single handed. I know the signs of sleep deprivation. If it gets bad enough, you start hallucinating - no meds/herbs required.
Standard Horizon sells a VHF radio that includes AIS reception(no broadcast) and it isn’t appreciably more expensive than VHF radios without AIS reception. It outputs NMEA0183 at two baud rates, and it was easy for me to integrate the AIS output to my RM MFD - the model of which I can’t recall at the moment.
I did get the RM Quantum digital radar and like the ease of use.
In your situation I’d get radar over an AIS transceiver. If you haven’t bought your VHF radio yet (doubtful) pick up the Standard Horizon. It does add useful information to your electronic sensor suite at very low incremental cost.

I second that advice

We have also sailed lots of shorthanded miles at night without the gizmos. Surely waking up every 15 minutes and doing a horizon check can also get you by.
The new radars are light-years ahead of the old tech. No warm up, MARPA, better visibility and draw so little battery you can leave them on 24/7 if wanted. The close range, flat water vision is phenomenal.
That said, while offshore, frequently we will see vessels on AIS first or if no AIS and small we will usually see their lights before picking them up on radar.
If you could choose only one or the other, it is a tough call. Radar is the more intensive install, ais can be added more easily later.
AIS is so cheap these days, it is hard to skip. Using a system with all the bells & whistles, you can enjoy a lot more sleep than before.

Curios what radar you guys have
