ST4000 tacking functionality

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Cliff,

The Autopilot Controls feature of LightHouse II software does not support wind vane mode (and consequently Tack and Auto Tack) feature supported by Raymarine autopilots. That said, the MFD should not block use of this feature ... you may verify by simply switching the MFD's Autopilot Controls feature OFF when operating the autopilot in Wind Vane mode. It is quite likely that the autopilot is simply alarming in response to the alarm transmitted by the autopilot. When operating in wind vane mode, should the autopilot detect that entry into wind vane mode or tacking may potentially result in gibing the sailing vessel, then the autopilot will alarm and entry into wind vane mode or the commanded tack will be prohibited.

With respect to proper initiation of wind vane mode, the autopilot should be in standby mode prior to commanding the autopilot into wind vane mode.

Finally, care should be taken to ensure that the system's SeaTalk to SeaTalkng Converter has been updated with the latest available software and that the SeaTalkng backbone (may only consist of the SeaTalk to SeaTalkng Converter within a small system) is supplying power to the unpowered SeaTalk bus via the SeaTalk to SeaTalkng Converter.
