Which tillerpolit?

Raymarine or Simrad ? : standalone or NMEA/networked ? I wanted to upgrade from a Seafarer Mini Seacourse as this was functional but limited.

I decided to go for a Simrad TP22 because I had heard fewer stories of failure.

This may be because they are less popular than Raymarine hence there are fewer in use to go wrong.

I wanted to have the steer to GPS or wind option available.

The Raymarine ST1000+ has a convenient LCD which shows course, but which seems from stories to be a water ingress weakness.


So Simrad TP22 was my choice.

It does all the stuff but uses displays elsewhere to show info.
Boat compass for steer to heading
GPS for steer to waypoint
Wind display for steer to wind
 
A few years ago, PBO ran fairly extensive trials on various Navico, (now Simrad), and Raymarine tillerpilots. The conclusion was that they were all capable of good results within their ratings. Raymarine kept a tighter course at the expense of greater drive activity and greater power consumption. Reliability wasn't discussed, but the article did note, IIRC, that Navico housed their electronics in an internal enclosure. Since a weakness of tillerpilots seems to be water ingress from the pumping action of the ram, this might be an advantage. This point doesn't apply to the ST4000, which has separate electronics.
I've used both makes, I would agree with PBO that Raymarine units seem "busier". FWIIW, I find the Raymarine control layout easier.
Myself. I find coupling a tillerpilot to a wind vane to be of very little value.
 
I have been using for a number of yeatrs a Simrad TP30 (now has been upgrated to TP32). Very powerful, simple and reliable
 
Simrad

I used the Simrad TP32 on my Shipman 28.
It worked very well.
I chose the TP32 because the wheel over time was a bit faster.
I used to single hand a lot and it never let me down.
 
Re: Simrad

i had the small simrad and had nothing but trouble with it, i had to send it back to the manufactrues many times and it was away for a long time on each instance.

In the end i went for a Ramarine ST1000 this semed reliable for a couple of years then it stopped working last year a long way from home. (i suspect water ingress)

I bit the bullet and bought its big brother the ST2000 and not had any problems so far.

my boat only 22ft and gets used alternate weekends for 6 months of the year so you can't say its over used although it is on most of the time as single or short handed most of the time
 
My last boat had a simrad TP10. I went through 2 drive belts in 4 years and it suffered from water ingress. A week in the airing cupboard and a de-watering spray on the pcb sorted it out. I found it very slow on lock to lock time compared to manufactures specs. I purchased a Raymarine ST2000+ for the new boat about 2 months ago, too soon to report on reliability but I am very pleased with it's performance. Much faster lock to lock time, much quieter also the way it starts and stops seems to have a kind of damping action where as the simrad was very jerky. I know I would be better comparing a TP22 with the ST2000 but not able to do that.
 
I have used Raymaine 1000/2000s and similar Navico/SIMRAD on and off for 10 years. I have a preference for the more powerful and faster models of either manufacturer. Of the two manufacturers I would have a slight preference for the NAVICO, only because I find the control buttons for changing sea state and gain were easier to remember, and it is easier to grip. The NAVICO does seem to have a better autoseastate too. I have had various faults with both manufacturer models, of all ages. One problem being caused by excessive temperatures in windless hot summer days, particularly the black ones. So remember to keep them from cooking up in the sun. For a weeks channel cruising when short handed, I carry a spare one in the locker anyway.
 
Oh one other thing. I notice the Shipman 28 does not have a balanced rudder. So you might have problems with autotack if not set up just right. Suggest a) find another Shipman 27 owner and see exactly where they have fitted one, and if it autotacks OK. b) go for the faster lock to lock models.
