 Trustindex verifies that the original source of the review is Google. Maryland Boat Sales did an excellent job advertising and brokering the sale of my Sea Ray Sun Deck 240. John took care of listing and kept me in the loop as updates came along. Would highly recommend for brokering services.

 Trustindex verifies that the original source of the review is Google. Last year I bought my amberjack from Mike and John at Maryland boat sales. Before discovering MBS I searched everywhere not only for the perfect boat but a slip and reliable mechanics. After keeping my boat with them for a year now it’s safe to say I found all three at one place Maryland boat sales.  John was  great with the entire experience with the purchase of the boat and made it a very simple and pleasant.The  owner Mike has been more then helpful walking me through things such as basic up keep and any questions a new boater may need to know. I would also recommend MBS for your mechanical need. Gary and Derick got my 2005 amber jack running great they seem to know everything about boats and are very cautious and thorough Thanks again guys

 Trustindex verifies that the original source of the review is Google. From the first phone call inquiring about a boat, through the on site visit and showing my boat as a trade in, everyone from Jeff to Mike to Paul. Everyone was easy to work with ,very informative, answered every question and searched for the easiest way to make everything work. When they said they would do something they did it. When they set a time to meet they were there!  Very professional and friendly I have owned 14 boats and this was by far the easiest to buy!
