HI Solar,
I thought I posted a reply a few days ago but it doesn't look like it has appeared on the forum. I have the following Raymarine AP gear installed:
ACU-200
Evolution EV1 Sensor Core
P70 Colour A/P head:Sail
Raypilot typ 1 Lin Short Stroke 12v
ST1 to STNG Converter kit
Also had made up a steering arm attachment.
I have a Raymarine C70 plotter.
New AP gear works really well and handles the weight of the yacht easily. I would say fully laden over 8 tonnes. On another yacht I had the ST 4000+ unit but it always operated at the top of its range and regularly stripped the plastic cogs. Commissioning did present a few issues ie not reading correct headings. But once this was sorted by the technician (I did not install unit myself) all good.
Hope the above helps. By the way, you get a 2 year warranty with the equipment, but if you register online you get another year's warranty. At least you did when I registered the equipment.
