Boat Launching Procedures

So here it is.

I just bought a new boat and decided to take ‘er for the maiden voyage this past weekend.

This is my first boat and I wasn’t quite sure of the exact Standard Operating Procedures for launching it off a ramp,

but I figured it couldn’t be too hard. I consulted my local boat dealer for advice,

but they just said “don’t let the trailer get too deep when you are trying to launch the boat”.

Well, I don’t know what they meant by that as I could barely get the trailer in the water at all!

Anyhow, here’s a picture below. See for yourself.

What am I doing wrong?
