After 13 years of intermittently reliable service our Raytheon 4000+ autopilot finally died last week. Now this was one of the last autopilots made by that company to not need a separate "Course Computer" to operate and is still a very popular unit if a quick look around this marina is anything to go by.
A trip to the local Raymarine dealer brought a "kit" consisting of a p70 control head, an ACU-100 course computer, an "Evolution" EV-1 sensor (Posh fluxgate compass, Fred!) and a 4000+ Mk II wheelpilot drive unit. The latter is redundant in our case as I fitted one of those last year to upgrade our old 3000 long belt drive unit, so the new one will be going on eBay soon. Some €1500 in total to that point.
Now Raymarine have invented "Seatalk NG" to replace the original "Seatalk" referring to these as "Seatalkng" and "Seatalk1" respectively. This is a new "single rail" type system and the terms "Backbone", "Spur connector", "T piece", "Terminator" "Five way connector block" and "Elbow Spur" now have to come into one's vocabulary. You also need a lot more space in the instrument pod to accommodate these new connectors and devices and arrange not to bend the cables through a radius tighter than 4" (although they come rolled into 2" radius coils in the box!).
If, as many will, your existing, other instruments are of the same Raytheon/Raymarine suite, say ST60, ST70, etc., you will also need a Seatalk1 to Seatalkng adaptor block with it's five outlets and cute little green led. This kit is another €140 or so. If your plotter/GPS outputs NMEA 0183, this too is incompatible with the new system and you either need to upgrade this or buy yet another adapting device made by a firm called "Actisense" at €350 because the one claimed to work by the dealer just does nothing.
So, there it is. When your faithful AP finally goes T - U, expect major disruption, major expense and contradictions in the support available.
Oh, and Raytheon STILL insist that their new High-Tech system works best when connected to one of their ancient old M81105 Rudder Reference Units. Why couldn't they have designed THAT out when changing just about everything else?
