Hi, didn't really read all the posts above, so, tell ya what I do:
If I expended any funds, travel or otherwise, based on the borker's repressentations, if it's not true, sue their asses for your loss!
Frankly, I'm sick of hearing discalimers, like we are ot responsible: They are responsible! They are experts in the field and have a greater knowledge of boats than the general public. If you rely on their representations and they turn out to be in error or false, they are responsible.....PERIOD!
Only disclosing defects or specifications made by the seller is no excuse, again, they are considered experts in the field and you can hold them fully responsible for what is advertised.
Point of basic business law, and in every state expert knowledge trumps omissions, errors and common knowledge. It's what you can reasonably rely upon while relying on such expertise.
Of more people would hold these lying SOBs to what they say and advertise, it would certainly clean up the business. Same with cars or any other consumer purchase
If the boat does not meet your intended purpose AND you conveyed that purpose to the slaesman/broker, you're off the hook! Get alll your money
back and seek indemnification for any expenses. Good luck....
