Re: wind data to Raymarine ST 6000
John Clark
Hi Nick, sorry for the tardy response...just started new job and am in process of buying a house... On my SM with a Hydra2000 system the FFD with NMEA was installed however the NMEA output from the FFD was not used, so the two NMEA leads were folded up and taped to the back of the display. The FFD Display is the device that generates and transmits the NMEA data. Someone here said it is the violet colored lead, I think that is correct. . As far as steering to wind (STW) I did exactly what you are trying to do. I have a newer Raymarine AP (EV-400) with the ACU 400 actuator control and an Es78 chartplotter, I suspect the ST6000 will behave the same. . I ran the NMEA output from the FFD direct to the chartplotter on the helm and it feeds the signal to the AP via the Raymarine network. Incidentally my Furuno AIS transponder(thanks you SV Tritin) located at the nav station uses the same wire to send AIS data to the chartplotter. I have had no issues with the dual usage of the same wire. I have sailed maybe 2000nm in the STW mode. In sail to wind, the system is for the most part great. I use it primarily sailing close to wind. Other wind angles are more forgiving so I use heading mode otherwise. As one person said here, sudden wind shifts can outmaneuver the pilot. I have had this happen once or twice. I always sail with the preventer rigged so other than looking like a sailing rube there is no damage to the boat or sails. Stronger wind is better. In light wind when the motion of the boat affects the apparent wind angle the AP still works but I suspect it is cycling at least a little bit futilely chasing the moving mast...but it does hold course to the wind. (note it is not a lot of motion of the wheel but I can tell it is having trouble making up its mind.) Regards, John SV Annie SM #37 Brunswick, Georgia I
