Need a solution for a upcoming voyage

[NorthernMac]

Hey guys,

 New here and have a question

 I'm setting up a opencpn system and I need a autopilot for a below decks install on a 30' cutter

 The boat goes up and down the east coast of the US every 6mo, single handed with about 200W of solar and two group 31 batteries 

 I WAS going to use pypilot, and use a tiller arm mounted on the rudder shaft

 Plan was Pelegic, but their arm apparently needs up to 25 amps, and that doesnt seem to work with pypilot

 Any solutions, or is this pypilot just for very small boats?

Here is a picture of where I would be mounting the system, boat hook was just for size reference


   Thanks!
