Default Garmin AP "Direction Control"

I was reading the Furuno Sabiki mode thread and was wishing that my Garmin reactor AP had it, and then I discovered that it does (or at least I think it does). Apparently you have to enable "Direction Control" and then you can tell the AP that you want to go in reverse.

Anyone use it? Does it work well? I have a GHC 20 Reactor system, twins on a Grady 330 Express. Would love to be able to hold a slow course or even stay basically still while backing against the wind...

I've had a client call me that their garmin auto pilot wasn't working. turns out they had changed it to reverse mode. so it would not work forwards....

but never tried one going backwards.

Can't wait to try it when I get my boat back in the water (not until April, sadly).

Too bad there's no way to integrate my Yamaha DEC controls otherwise I could get a poor man's skyhook feature.

Not to rain on the parade, but I have a GHC10 and my understanding of the reverse feature was simply you can use the AP display to change from fed to rev gear if your setup allows. I didn’t read it as the ability to operate the AP in reverse but that would be awesome if it were the case!!

Unlike skyhook the AP has no control over throttle going in and out of gear. If set to go or stay near a waypoint it is just going to pull past it and circle around. Sounds like a total cluster to me but I don’t have a CC so fishing off the bow is not something I’m interested in.

I know this thread is almost a year old, but I was curious what you found regarding the Garmin and "Direction Control"? I assume it does not work like sabiki mode, but wanted to make sure. I am ready to pull the trigger on an AP and want to use Garmin to match my plotter, but I love that sabiki mode option on the Furuno 300. Has me completely torn on my final decision. Does anyone know if Garmin planning anything similar on their Reactor 40 w/ v2 pump?

Yes, I've used it several times this summer with varying success. It does exactly what you'd expect -- it tries to hold the boat's direction, but in reverse instead of forward. I find that it's only effective in holding your position if there's enough wind or current that you need both motors in at least idle to back against it. Otherwise the system will frequently turn the motors all the way to one side in its attempt to hold the direction, and you get a bunch of pump stall warnings. I'm assuming stalling the pump a bunch isn't good for it so I only used it when that wasn't happening much.

Another important note: once enabled, it's easy to accidentally put the autopilot in reverse mode which causes all kinds of fun when you're actually going forward, though it's smart enough not to allow you to use it when going fast. So I always disable the feature from User Setup when I'm not using it.

So bottom line is that it's pretty useful in some circumstances and does work as a poor man's spot-lock. To use, back the boat against the wind where you want it, enable reverse, and activate heading hold. Then adjust your throttles as needed.
