Well, sorry for the drama everyone, it looks like the broker may have overstated the sellers unwillingness for a sea trial, or he had a change of heart. The seller agreed to a sea trial, will wait until the normally scheduled launch date and person doing it, and will even drive the boat for me for the trial. New agreement was sent by the broker with contingency for survey and sea trial. The launch guy normally charges 250 dollars for it, so that is all I have to pay, plus surveyor for a couple hours.
At this point the wife and I are feeling good, this is the model of boat we chose together, and the price is right for us. Hopefully all will go well and we will be the owners sometime in early to mid May! Thanks for all the advice everyone.
