I'd stay clear of the navigator/hunting party combination. It's very bad when your hunting parties discard all your junk and the navigator shuffles it into a new (curse filled) draw pile. The chancellor is better but I'd have stayed clear of that too and taken silver. I may even have stayed clear of the mining villages as well, or at least trashed them for value quickly. I'd have focussed instead on the hunting parties repeatedly finding the key cards: silver, gold, trade route, and witch. If you limit the variety of cards in your deck you can be pretty sure what your hunting party will find. The hunting parties will even find other hunting parties more often.
You probably also needed to change the speed that you developed the deck in response to the cursing. You needed more hunting parties and could have taken some instead of green cards on turns 10-15. Duchies also pollute the drawing of the hunting parties. If you look at your final deck composition it's not surprising that it fizzled out. Not much treasure, not much drawing, lots of green cards to clog up whatever drawing you had.
Having said all that, other people's style of playing hunting parties may be quite different to mine, quite possibly with more success!
