Sounds like you want to sneak onto the yard after dark to escape paying the
$40.

To enter the yard and look at the boat I must pay $40. I have learned
that since I have a bill of sale for the boat, no matter what the
Department of Motor Vehicles says, I don't own the boat and can't unless
the current owner gives me a signed letter releasing interest in the
boat to me.

I'm going to walk away from the boat and let it be auctioned away unless
I can somehow get a clear title for the boat.
