Ours is set up where one person can sail her but she’s big enough that getting in and out of slips, tiering off, etc. is really a 2 person job. There’s a 50 ft aft cabin Sea Ray down from us, gorgeous boat by the way, that 2 people could handle well. Our Marina managers have over a 60 footer but it looks so big not sure 2 people could.
I knew someone who had a 42’ Chris Craft twin screw cruiser. He would back into the slip using gearshifts with engines at idle. Gearshifts outboard, throttles inboard.
One night he powered back to the marina with a little rum under his belt. Turned the boat around & began backing toward the slip. Needing to slow, he reached for the gearshifts. But with his eyes on the slip his hands grasped the throttles and....well...POW!
Large boats nowadays have thrusters for docking. Amazing to watch.
