cuddles 35 essentials
Instead of the winged keel, which will be torn off when "banked", may I suggest 2 more think keels running down either side of the hull. These will stay clear of obstructions and can be made thick and strong to prevent roll.
Also, The cuddles manoeuvres like a pregnant yack at slow speed. Obviously due to the combination of single screw, sizable submerged displacement, and small rudder.
If doing a complete overhaul, a bow thruster and rudder extension would be a god sent. I used to love taking my cuddles out for the weekend but loath berthing in a crosswind when I was by myself. A bow thruster would be at the top of my list.
