Self Steering!

Hydrovane... 
For Distant Horizon to be completely ready for her trip to Bermuda, there are still some items needed. The first item, is the self steering system.  This is effectively an autopilot that does not need batteries. I chose Hydrovane for several reasons:
  • it can be used as an emergency rudder
  • it is does not connect to the main rudder; reducing overall wear to the steering system. 
  • I can still turn the wheel in an emergency
  • it can be used in conjunction with the existing autopilot system
The Hydrovane was ordered with the optional 3nm LED stern light. Having an AIS to know what ships are in the area is one thing, but having those ships see us better... priceless!

Once Distant Horizon is balanced, she will sail straight for a considerable distance without me making corrections with the wheel. This is due to the modified fin keel. Eventually, she slowly turns toward the wind and I have to make a course correction with the wheel. With the self steering system, the windvane will fly straight while the boat is on course. Then, when Distant Horizon turns slightly, the windvane will be deflected by the wind change. That deflection will, in turn, cause its own rudder to move; turning Distant Horizon back on course with the windvane flying straight again.

The order has been placed for the Hydrovane. It is scheduled to arrive in mid-March; leaving me plenty of time for the installation.
