A) a really good hard-working
broker is probably worth the commonly-quoted 10%.
B) The other 80% of the brokers are worth a lot less -- and in the bottom 25% are the ones that are only in it for the tee times and liquor.
C) It takes as much (or more...) time to complete the sale on an 8' dinghy as it does a 30 footer. People just seem to agonize more over smaller stuff and $. This drives the good ones crazy.
Agreed that "low priced" boats are the hardest ones to make any $ on.
D) Sometimes a local surveyor can give you a short list of good brokers. Ditto other sailors.
When we were shopping hard, with cold cash in hand, we found some that were really hard working and quite a few that..... well.....
The guy that completed the sale to us was worth whatever the seller paid him. He was honest and helpful.
Nowadays I'm retired from my day job, and once masqueraded as a yacht broker for a few years, several decades ago. I loved meeting the sailors, but it was a difficult way to put food on a table, on a year-round basis.
