    If you are doing lots of sailing short distances (like in the Bay), with lots of tacks and gybes, then you want an autopilot. If you are doing longer distances with not so may tacks and gybes, then the wind vane. If your boat is very light and will surf easily, then an autopilot. If it's heavy and you want it to track down wind in big wind, then a wind vane.

    And make sure you learn the bungee cord methods of steering in this video: https://www.youtube.com/watch?v=PY1qx3PfUS0 and the associated book. I know of one guy who crossed the Pacific using this method after he read the book. This will negate the necessity of having a duplicate wind vane or autopilot.

    "would a Hydrovane with a Pelagic tiller pilot (to run the hydrovane if the windvane part breaks) count as "two autopilots" in your book"

    Not if you are going to Hawaii... this setup still has a few potential "single points of failure" that might take it all down. Such as what could happen if you are pooped by a big wave from astern (which wouldn't be unusual the first few days going to Hawaii). You want two 100% independent self/auto steering systems. I get folks dislike cutting rudder tube to install a below deck autopilot... but below deck systems are maybe 5x to 10x more reliable then above deck systems (its that sun/heat and salt water thing that electronics dislike). If you go for the above deck pilot... have a great canvas cover built for it to keep direct sun and water off it (as best you can).

    Last...
    The wind vane is probably just fine if you are cruising... or treating the race to Hawaii as an "adventure cruise"... but vanes just are not good enough if you want to "really race".

    Now...
    I have zero real world experience with a vane... but cannot imagine how it would do with a spinnaker up in 20k+ (which a pelagic autopilot will drive in all day long while you sleep).

    I'm afraid I will sacrifice respect by saying so, but this is me: "or treating the race to Hawaii as an "adventure cruise"..."

    That doesn't mean I don't want to be safe, but I won't be flying a spinnaker and the extra distance I might sail due to course wander with a windvane does not bother me enough to avoid a windvane.

    For cost reasons I cannot do a belowdecks autopilot and a windvane, or two belowdecks systems. Right now I'm thinking I'll do a windvane, and then consider getting one of those CPT wheel pilots as a better backup (the EV100 does not feel like a backup to me). I had hoped a tiller pilot for the Hydrovane might be sufficient, but understand the single-point-of-failure argument.

    Thanks again for the comments and advice!

    PS: @Foolish : Many thanks; I watched the video, which was quite interesting. I have a wheel, not a tiller, so how to rig that system is less obvious for me. I might check out hte book, though, in case the wheel question is addressed there. Reference/video link are much appreciated.

    Oh I missed you have a wheel already... so you have a below deck quadrant. That makes a below deck autopilot pretty straight forward/easy... maybe talk to Brian about what he would recommend for the Pelagic... maybe you can get away with one system and one or two "Brian recommend's" spare parts.

    Thanks; I assume Brian is associated with Pelagic? I had not appreciated until recently that Pelagic and Monitor seem to be owned by the same folks, and local, so perhaps I can take the boat over and get their opinions on approximate costs/complexity of doing either system on my boat. My steering is rack & pinion (Whitlock/Lewmar Cobra system), so unsure if the rudder connection for a ram would be as simple as for cable-based systems.

    @JimQuanci : Do your comments imply that an autopilot (or at least a Pelagic) can steer a fin-keel boat downwind well even (e.g.) in a quartering sea? I'm trying to read between the lines about the spinnaker. In fairness, I am unlikely to fly a spinnaker, so this is more a curiosity question; I watched the Monitor wander back and forth a good bit downwind, not that it seemed to be a problem.

    One of the bottom spokes on your wheel will act the same as a tiller. ie. if you pull a bottom spoke towards you, the boat will steer away from you. So set up the bungee cord (or surgical tubing) the same, but connect it to somewhere near the middle of the bottom spoke on your wheel. This should do the trick.
