Brian-One further comment on your autopilot. You can also set it to hold a
constant apparent wind angle. If there are wind shifts or varying true wind
strength you will observe a lot of course changes by the autopilot to keep
the steady apparent wind angle. With wind shifts and the boat changing
headings to keep the steady wing angle often you look like a DUI sailor and
others sailing around you often are trying to figure out your next move.
The key in this mode is to be very alert to the other traffic so as to not
cause confusion on the autopilot's actions in this mode.
Check out the Canadian equivalent to our Inland Navigation Rule 8 (the same
as International Rule 8) which for action to avoid collision requires action
to be positive and in ample time all with the observance of good seamanship.
This means in a practical sense to get back to manual or correct the
autopilot to make those positive moves in ample time for all situations
where you have to hold a constant course or change to give way. (My
Captain's license is speaking here.)
If in open water with little traffic, the constant apparent wind angle
autopilot setting is great for learning how to optimize you sail adjustment
for top speed.
