Background then Question:

We have a problem where our trailered boat does not set properly on the
trailer. When we pull it onto the trailer the bow is touching the bow-stop
on the trailer. But as we pull the boat & trailer up the ramps the bow post
moves a bit away from the boat so that the boat's bow ends up 2" or 3" from
the trailers bow-post.

This is ok for short distances but when we trailer longer distances, the rig
rides much better if the boat is touching the trailer at the bow-post.

On most boat there is, of course, a bow-eye and you just pull the boat
forward with a winch. But this boat is an older wooden boat. It does not
have a bow-eye and we can not install one -- it would just pull the bow out
of the boat.

The boat *does* have lifting rings at the bow & stern. These were meant for
a straght up lifting of the boat. This is how the boat is supposed to be put
into the water.

We can put some pull on this lifting ring. And, possibly, we can reinforce
it so we can put more pull on it.

So...my QUESTION:

The boat weight about 4000 lbs. I've done a little googeling and read about
coefficient of friction.

#1: Am I right in thinking the Coefficient of Friction can not be more than
1.0
In other words, the MAX force needed to pull the boat forward is 4000
lbs.

#2: The boat (painted wood) sets on four carpeted bunks. Am I right in
understanding
that the amount of surface area between the boat & bunks does not matter as
far as
increasing or decreasing the friction?
