Garmin auto pilot on 7m rib

As any body got one running on a rib. It's required as I spend a lot of time at 3-5 kots crossing the channel and it would be easier to have a computer steer? Would this work at such slow speed? Thanks

I have one of these on BP, nothing fancy, does what it says on the tin & works down to 3kn. Self install in about a day if you're handy with spanners, which are included in the kit. Integrates well with the plotter, takes up no room at all on the console which is a bonus & cost about 600 quid. It steered us from Anglesey to Dun Loaghaire without a hitch, it tended to fight the sea a little when it got lumpy But I've ironed that out now. It's one of those things that you don't think you need until you get one & the wonder how you managed without.

There was one on the big redbay that JK hired last year. It was impressive, just pick your destination, press go, set the throttle and it took you there. I could see it would introduce a potential for falling asleep though; so it may be worth setting a "watch alarm" as used on large ships. The other 'risk' especially on a cabin rib - is it would seem tempting to walk off and leave the boat steering itself. That probably means you are disconnecting the kill cord. The concept however for long distance cruising was great, especially if the boat is a means of travel rather than part of the fun.

No, Raymarine but it works on nmea 0183 so is compatible with just about any plotter/ GPS. It's specifically aimed at small boats with seastar hydraulic steering.

Don't really see the benefit on an open rib, as it all does is relieve steering duty. A vigliant watch still has to be kept, especially at night.

Nice on a large yacht where the primary nav equipment (radar screen) may not be in the cockpit.

In open sea without landmarks it's very useful as it allows you to keep your eyes on the road, instead of watching the instruments. Plus it steers a dead straight course, which in theory saves fuel.

It might do if you set it up to steer a bearing but IIRC the Garmin was steering to a waypoint so was making fine adjustments for the error from tide / wind etc.

Shouldn't do, if the pilot's configured properly. It'll accept CTE data from the gps and work out a course made good. Or it can still just hold a bearing if required.

Are we not agreeing there? either it can simply steer to a bearing (from compass) or it can steer to a waypoint/route in which case it will continually be correcting for the errors caused by wind, tide etc.
