Raymarine Instruments upgrade, Autopilot Wind Angle

[William C Bonner]

My 2007 Beneteau 373 had Raymarine instruments and a garmin chartplotter when I bought it last year. The raymarine instruments were older units using SeaTalk1. (ST60 Tridata, ST60+ Wind, and ST6002 Smart Pilot Controller) The Garmin unit was not connected to the Raymarine units. 

I've upgraded the chartplotter to a B&G ZEUS™ 3S, and added a Raymarine SeaTalk1 to SeaTalkng converter kit, allowing all the wind and water details to be displayed on the chartplotter. 

I've been thinking about replacing the wind and water instruments with B&G units, but don't want to lose any existing functionality, and don't want to change out the autopilot anytime soon. The main feature I'm concerned about is using the autopilot to steer to a wind angle. 

Does anyone know if the Seatalk Converter will work in both directions and send the wind details to the autopilot if I were to get B&G wind instruments and connect them to the NMEA2k/SeatalkNG network?

Thanks, Wim.

I had a similar situation with my 2010 B34. But I replaced the raymarine plotter with a B&G Vulcan 9. I have now got the upgraded Autopilot, B&G WS320 wind, B&G V60 radio and a Fusion radio. I still use a DST200 speed depth temp, which is on a SeatalkNG backbone.

Seatalk NG is essentially NMEA 2000 compliant, so joining the 2 together is fine, you can either make a hybrid backbone or just use one or the other with adapter drop cables from SeatalkNG to NMEA2000 or from NMEA2000 to SeatalkNG.

My network therefore has Raymarine STNG backbone components, NMEA2000 drops to the B&G MFD and Wind. The newer EV100 Raymarine Autopilot was an upgrade from the st6002. This gave some important updates, specifically the head unit P70S. The network talks without issue but there is one major caveat. The st6002 autopilot cannot be seen reliably by the B&G MFD, nor can it be controlled by the MFD. This was part of the reson I upgraded to the EVO100 (kept the wheel as it is still the same). Although you cannot control  the EVO100 via the MFD you can steer to a course or wind as the network does share all of that data.

The old st6002 would sometimes allow me to set a course and follow it on the MFD but was unreliable, it would sometimes not work at all and sometimes would.

The wind data from my WS320 B&G anenometer shows up on everything as it should so I have expectations that a newer DST810 (water speed, depth, temp) would just as well.

So my advice - replace the Autohelm course computer and head unit. Also if you haven't got one already I would strongly recommend a rudder reference unit.

Cheers

My boat is different and I cannot answer the problem.  I single hand my B35.  I set the autopilot wind angle at zero (into the wind) while furling and unfurling.  It holds steady and allows me control flapping while tightening the sail.  No jambing.
