Here are a few points about the benefits of using a boat dealer/boat broker to sell your boat.

The experience and expertise of a professional boat dealer may achieve better, faster results when selling boats. Apart from knowing about boats, boat dealers increasingly extend their boat sales service to include features that cater for all aspects of selling a boat. A Dealer knows what buyers are looking for and will advise you on how to make your boat attractive to appeal to prospective boat buyers. Some dealers offer maintenance service and berthing of your boat at their marina/yard as part of the deal. Others offer marketing strategies that include advertising your boat to the overseas market if appropriate.
An experienced boat dealer will know the best price that can be achieved for a particular boat. Setting the price too high may keep an interested party away, setting it too low means losing out. Being a professional in the industry gives that 'insider knowledge' by being in touch with both parties, the seller and the buyer, around the clock.
The boat dealer acts as the agent between seller and buyer and is free of the 'emotional attachment'. He is selling just the boat and will negotiate on the basis of market value and price achievable.

Boat dealers get better rates with advertisers due to volume. They know how to get the maximum exposure for your boat on a continuous basis.
Boat dealers may go into co-brokerage arrangements with other dealers, which maximises exposure to boat buyers. When a boat dealer has a buyer but not the boat he will try to find it at another brokerage. For a boat sold by co-brokering, you don't have to pay more, but the boat dealers will share the commission you have agreed to pay in the first place.

Most boat dealers maintain a customer database of potential buyers. Being able to bring together the seller and buyer in a time efficient way, means a sale can be achieved in a very short time.
Your time is valuable. Professional boat dealers have the time and resources to manage all aspects of your sale. Boat dealers are always available for enquiries and to arrange an inspection of your boat at short notice. The boat dealer will also make all the arrangements for a survey and sea trial.
Managing the legal aspects of the Sales Contract are an important part of any sale. Professional boat dealers understand all legal aspects of a sale, such as the Offer process, encumbrances, special conditions, transfer of title and also operate trust accounts to hold deposit funds.
