Hi Friends,

My 2008 Hanse 320 came with the Raymarine ST 4000 MK2 Wheel autopilot. I was wondering if anyone has any other type installed and if so where/how specifically does it get installed?

p.s. I am planning a long trip next year and must have very reliable auto pilot. During maintenance of the existing wheel drive pilot, I learned Raymarine uses RS-555SH motor (same one in RC cars, drills and fans ConfusedOuch). Quite shocking actually that they would use such cheap motor.

Thank you

Most pilots on Hanses are Jefa drives. Itís below deck, mounted on the rudder, fast, strong and reliable. Itís more expensive, but definitely worth it. 
You also need a course computer like eg the Raymarine EV 200 and a P70 display. All together around 4000 euro.

We have to admit that owning a sailboat is quite a costly hobby. Most Hanse owners have to choose between all the nice (read "expensive") things, that are absolutely needed, or maybe just nice to have.
A lot of years ago I bought a Raymarine Wheel pilot (adviced for boats 32-37 ft) with the Smartpilot controller ST6002. Has worked just fine since then. When I started sailing in rougher seas, I invested in a Jefa DD1, and mounted it with a switch, so I can choose between the wheel pilot and the DD1.
The ST6002 had some problems in really tough weather. The standard values had to be adjusted, because they could not cope with a boat thrown 40-70 degrees off course in 6-7 meters of waves. After correction of these settings, the Raymarine worked fine.
I have checked the price of the very nice Raymarine EV 200/300, with P70, and the EV1 sensor which is a few generations better than the fluxgate compass. BUT! - I have problems convincing both myself and my wife that it is "need to have". As she says, we can spend 4 weeks in a nice apartment in the Canary Islands for that price.
So I guess that the old autopilot can stay as long as it still works allright.

Why not maintaining the  "cheap" Wheel autopilot and install a nice Hydrovane for rough weather and long passages?
In my opinion, moneywise,  the wind pilot is more reliable indeed (and does not consume energy)

Hi SailCS33,
For what its worth, at risk of starting a forum rukus?

I bought my H315 [2007] 3 yrs ago, I wanted a good reliable Autopilot at sensible price. The drive must be below deck.
I looked at Jefra direct drive system. I found it overly expensive, however it may be easy to install.
A look round at other systems, and various Forum threads. Jefra is neat smart bit of mechanical engineering, but a fair number of reported fails in both the clutch and gears. Looking at the Raymarine Linear drive, its simple and been around for some long time, It uses a recirulating ball lead screw, nice motor, nice enclosure, and easily detached from rudder by pulling one pin. The leadscrew means that does a lot of the gearing so clutch lightly loaded. The Mk1 version, had few issues, seems to me  engineered out in Mk2. My only reservation was a worry that the lead screw would give resistance on Wheel when disengaged. It does not;  you dont feel any resistance on wheel.
I chose the Raymarine Linear drive,  their controller and compass, subtantial saving on Jefra. Fitting needed some basic engineering and no real problem. The system is good and holds course in adverse conditions, even downwind in biggish rolling sea. The price is low enough to carry at least a spare Drive if planning long off shore passage. I hasten to say I'm not planning long offshore,  as I approach my 80 year birthday. Yes I'm an old fart sailing for 50 years, dont throw my limited funds about.

One final note when fitting the drive I found that Hanse had fitted the wrong offset angle arm and compensated for an over long push rod arm by turning the arm back to front which meant the wheel full over to stbd gave 48 deg rudder and full port gave 28 deg. I had to shorten push rod and reset the arm? All good now. But I wonder how many Hanses have badly aligned steering? I did write this all up with explanation drawings, on an 2011 forum.

Perry, I agree with you regarding the steering setup, my 370 (2005 and owned from new) had a similar bias in its steering geometry. Resolving it was just a case of properly adjusting the linkages, which should have been done in the original build. As regards Jefa equipment, yes it is well made but so are other manufacturers. As you point out itís about evaluating each systemís design and build properly for what you want but the single most important aspect for long life is usually planning and detailed attention to the installation.

My experience of Jefa is generally good product and components but at a price that often appears hard to justify.

SGRHMA2,

This I hope is a link to my previous stuff aout my offset linkage. It wasnt just they fitted a 10 deg offset [by my calc should be 5 deg] arm but then because the pushrod was too long they turned the arm upside down and doubled the error.

Thank you Perry,

Would you happen to have any pictures to show how you mounted the linear drive?

SailCS33, I will be on boat late tomorrow after my Wednesday club bike ride. I will try again later to get useable photos. its difficult to get photos in the rear locker that can be interpreted.
I fitted a thick aluminium plate running for and aft, bolted through the transom [using a bit of Aluminium right angle extrusion] and at front bolted to the bulkhead. The pivot mount under the linear drive bolts to this plank I think the aluminium was 3" wide 3/8" thick about 15 " long. I fabricated a tiller arm keyed onto rudder stock at right angle to the Lewmar tiller arm. I fabricated another lighter weight arm to connect the rudder position sensor to the tiller arm that connects to Lewmar pedestal fitted at 90 degrees so the rudder sensor was push pulled in the for and aft plane on the port side of rge boat [the oposite side to the Lewmar push rod from the Wheel pedestal. Sorry if its double Dutch but hard to explain.

I maybe asking for something you already provided a while ago. Are these the photos from you? https://www.myhanse.com/uploads/5043/Doc_with_6_photos.pdf
