We offer a full service department and complete sales department. We are new boat dealers for Manitou Pontoons, Scarab Jet Boats, Evinrude Outboards, and EZ Loader Trailers. We also have a great selection of used boats and yachts.

For our back harbor channel entrance take a look at the photo with the markings on how to get into the channel. Keep in mind you do not want to be in-front of the big house on the up river side or the big hill on the down river side. The idea is to come in the channel on the same angle as the first slip. During normal season a 1987 32' Carver Mariner will be at that dock & if you head towards the stern of that boat until you get in the channel you will be safe. It is 5' to 6.5' in the back harbor. If you draw more than 4.5' it will be safer to put you in one of our front harbor slips out on the channel. Though we have had boats that draw 5' go through just fine. If you are taking a slip at our fuel dock ALWAYS bow in on your starboard side to be on the safe side. We have good depth at the fuel dock but the stern is safer out towards the river (Plus the view is better looking out at the trees!)
