We found during several of the night passages last year that the electric autopilot used up too much 'juice' from the batteries.  During the day this is not a problem as our Solar Panels produce enough amps to drive the fridge, instruments, plotter and autopilot.  At night of course the solars do absolutely nothing.
 
We decided to buy a 'Hydrovane' which is a make of windvane steering that has it's own rudder, rather than using the boat's rudder.  This means that that we can turn the autopilot off and also if we have a steering failure on the boat we should, hopefully have backup steering.  The insurance companies like this!
 
We had the Hydrovane shipped to Gibraltar from the UK manufacturers last August which we collected during our passage west through the Mediterranean. It was fitted at La Linea Marina in Spain (right by Gibraltar) by Ted Devey.  He is a recommended installer who works freelance and happened to be in the Gibraltar area.  The fitting took about 4 days but seems to have been done well.
 
When we sailed on to Portugal via Rota last September we did not use the Hydrovane as we didn't want to have to experiment at night in the dark.
 
So our first outing with it was on a trip from Albufeira from Portimao on 3 June this year and it was an encouraging start.  We tried again when we sailed from Albufeira to Isla Culatra today.  The wind was about 15-18knots on the beam and as our speed started to go over 7 knots the vane had difficulty coping.  Changing the 'gear setting' on the rudder brought things back under control.
 
Here is a picture of this second test:-
 
 
 
For any sailing techies out there - the Hydrovane website suggests we put a tell tale on the vane to help adjusting the vane so it is exactly in line with the wind direction:-
 
 
 
This helped enormously.
 
Most sailors give nicknames to major items on yachts so at the moment our Hydrovane is called Carly (you're so vane)blog
