Using A Broker
The listing broker represents the seller and has no legal responsibility to the buyer. I bought boats using both methods (dealing directly with the selling broker and with a broker that I chose to represent me). The advantage of using your own broker is that you have an experienced person representing you in the purchase, who can often stand back from an objective point of view and steer you along the straight and narrow. They also have experience in who the best surveyors are and negotiation with the selling broker (which could result in a reduction in price that you may not be able to achieve yourself). Your broker (the buying broker) normally gets half the commission from the sale so it should not cost you anything (some will charge incremental costs if they have to travel etc.).
