Re: Towing from radar arch Poss!
Ski pole is nice, but before them came the single transom eye for I/O's and duals with lanyard for OB's. The dual/lanyard setup ( 2 snaps, line across behind engine and 3rd hook on a roller for the ski rope, that allows the ski rope free access to pull evenly in a 180 degree ark) minimizes the steering torque interference with the engine and by being close to the water has little to no effect on the attitude (uprightness) of the boat.
Tieing anything high is just asking for problems as Tas said.
