Autopilot
We have a little 18.5' Bomardier Utopia. It is a jet boat powered by
a 200 hp Merc. One of the characteristics of jet boats is that their slow speed handling is lousy. You really can't take your hands off the wheel. I was thinking of installing some kind of hydraulic or electric autopilot, but have virtually no experience with them. The boat does have a Garmin 182 FF/GPS, so I presume there's a NEMA stream available. Is this possible? Does it make sense for a small boat? Has anybody done it? Recommendations? I'm not concerned about navigation, simply to be able to take my hands off the wheel and have the craft continue in a straight line... (Note: I have substantial experience with large and small power and sail, but all of it is over 30 years old) Thanks, -- Larry Email to rapp at lmr dot com |

Larry,
I'm not at all familiar with your boat, but would there be any way to rig a tiller pilot to work? These are devices designed to by used by sailboats w/ a tiller, but are often also used with some wind vanes (like the monitor). They steer the boat to a compass heading, but most can also be interfaced to accept NEMA and steer to a waypoint. Cost new starts about $300 L. M.

Larry,
These are not neccessarily the cheapest sources, just the first that came up when I Googled Tiller Pilot http://www.ginasvineyard-marina.com/raysttilpil.html The Raymarine's entry level is the ST-1000. It accepts NMEA http://www.vitelectronics.com/smtp10.html Simrad's entry level TP-10 does not, but it is cheaper. The TP-20CX and TP-30CX do accept NMEA. http://search-completed.ebay.com/sea...ompletedonly=1 They also come up on Ebay every now and then. L. M.

If all you need is to hold a straight line, you don't even need to hook up the NMEA. The autopilot will follow the magnetic course you start it on with its internal fluxgate compass. I don't know how to mount a tiller pilot on a motor boat. I use one on my sailboat with the emergency tiller. I do plan to hook up the NMEA but it works without it.

Rodney Myrvaagnes NYC J36 Gjo/a Thanks, guys, Well, I did a little research and I'm not sure a tiller pilot would work. The inexpensive models seem to be designed to connect to a conventional tiller. When you step up a bit, it looks like you replace the wheel with a new assembly. I'm going to have to first figure out what kind of steering linkage is being used he I know it's not cables, but I don't know if it's hydraulic or mechanical. Then I have to figure out how much travel, and whether or not you can move the jet without turning the wheel; i.e., if you turn the jet, does the wheel move or does it even matter.... I'll keep looking and report back here. I tried two suppliers yesterday, but both said I needed to talk to the manufacturer. The manufacturer says I need to talk to the dealer. The dealer doesn't know... Figures... -- Larry Email to rapp at lmr dot com |
