I just went through this for my much smaller boat and ended up going with a Simrad
2402 system driving a hydraulic linear ram. It is powerful enough to power a drive unit sized for your boat. I also have a Monitor
. There is quite a lot of online discussion on this topic in the Electronics
forum and in the end I choose the Simrad
due to it's stellar reputation and ability to intergate with some future electonics on the wish list. The Binnacle in Halifax
can supply either Simrad or Raymarine
depending on your choice. $$ are similar.
We kept our boat near Mahone Bay for about 9 years before moving it up to the Shediac area. It's a great place to cruise
and a Kanter46 is a very nice boat. Best of luck with the project
and sailing plans!
