Boat Lift Cradle

[crystal waters]

This lift looks really very narrow for supra. Or the format of the photo makes it narrow!!

The advice you have received is spot on!
All I can add is to provide a “stop” to prevent boat going too far forward on the lift and thus preventing your prop shaft from striking bottom cross member at rear of lift.
For mine I have made a mental note exactly where to stop the forward motion to prevent same.
