The Archer I built my hour on years ago was ferried from LAX to Honolulu then Hona to Pago Pago then Pago Pago direct to Ashburton South Island NZ.
The pilot had to climb over the ferry tank to get in and was just over 1000lb over gross on takeoff from LAX. It had autopilot but imagine sitiing for the 12 or 13 hrs over the sea between landings watching the oil pressure gauge waiting for a problem.
