@Davidpm that is not true. All brokers co-broker throughout USA and world even. A very few number of vessels are not available for co-brokerage though this is looked down upon in the industry. Brokers do have more incentive to sell their own listings so may push those yachts. Sharing commission is very common.
@skippyman it is as much a mystery on the brokerage side about how to meet clients. One way is just start seeing boats around town and meeting the local brokers. Find one you feel comfortable with think has integrity and then work with them. Another way is to go to a boat show and shop for a broker you like. A buyer broker is a good idea.
