Addressing the setup. The actual orientation of the boat on the trailer should be the boat has a slightly bow up attitude.

When on level ground, the water will drain out with the stern plug removed.

If you trailer some distances or frequently more than 20 miles, you will want the boat to sit as low as possible on the trailer. Trailers with torsen axles allow hulls to sit down below the frame.

As for launching/retrieving, ramp geometry, trailer depth and boat height off the ground are key measurements.

On a steep ramp, the higher off the ground the hull is, the deeper the trailer needs to be submerged.

I estimate 7 out of 10 boaters who launch/retrieve submerge the trailer too far/not enough.

I think you are not submerging the trailer far enough on retrieval.

After learning from members, I reconfigured both my trailers. Both had something positioned significantly wrong.
