All kidding and snipping aside. What one can do is one thing if nothing goes wrong. God forbid, what happens if the captain goes aground, someone get hurt. Who is responsible? The customer chartered the vessel, hired a captain, and off he goes on a cruise. True, the attorney will write the contract, what is in the contract assigning responsibility in the event of an accident. No I am not an attorney but a good friend of mine is a maritime attorney, we have discussed this issue in the past. His comment bascially, if it goes to court, given the way maritime law works it could get quite messy.
Everyone wants to make a living, I have no objection to what people do given it's legal. pascal quoting a price in a forum, that was not the information the OP was looking for. Perhaps taking it up in a PM would have been more prudent. Talking price when referring to quotes from other sources is not the same as quoting your price. Moderators have admonished people in the past for the exact same thing, this is what rubs some people the wrong way. Rules are rules, often times people play the rules for their own advantage, this can be as agrevating as people who just blatently break the rules.
Recently there has been talk of tightening up the responsibility of the license holder, possibly this is one of the areas they want to tighten up on.
