Kukka has a relatively narrow chord keel, and the rudder is more spade than skeg, esp with the proximity to the prop skeg section, I'm not surprised she backs up alright.. Nice compromise.
Of course you're planning to sell that bow thruster (spelled C-H-E-A-T-E-R) to some truly needy W32 owner, right?
