On the other hand...
If a person is really interested in a boat (and I mean, seriously interested) then a 10% deposit is fair. Giving the name of the owner is a sure way to introduce too many variables in the process (or having somebody do an end-around, which could indeed lead to them loosing their 'lousy commission' which happens to be their paycheck!) Remember, the owner CHOSE to go THROUGH a broker, perhaps because they didn't want to be answering questions from everyone who kicked the fenders and made low-ball, non serious offers? A broker in this case serves as a screen for the seller.It seems odd to ask for a deposit for a sea trial, but not to ask for a deposit in preparation for a sea trial (that is, an offer.)As for starting the engine, Steve M gives the best reasons why one shouldn't just "Start 'er up". Another very good reason is that insurance premiums change if the broker is in any way in "control" of the vessel (and yes, that includes starting the engine.) In Michigan, the worker's comp category for agents who control a vessel with passengers is the same category as test pilots. (That category level is dramatically reduced if you're actually a licensed captain though...) Think about that insane premium for a moment, and just to start an engine!?How many people would ever think to make an offer on a house with no deposit, ask for the owner's name (to circumvent the Realtor) and request a 'test overnighter' when purchasing a house? Why do we get in such a huff about these things when we buy a boat, which can be a significant investment?Generally speaking, a broker is like any other profession - you get good, you get bad, but it's probably not fair to malign the entire profession based on the actions of some.Regards,Dave Crowleys/v Wind Dreamer
