This will help avoid floor damage.- Google Patents US3154039A - Stable floating foundation You should paint the surface of the flooring with marine paint and also use a paint protector (top and bottom). Once you have the marine plywood installed, you will be ready to frame your new boathouse. If you have two or more pontoon boats in the rear row, attach steering linkage assemblies to make steering easier. On forward boats, you should remove these components. If you want to be able to propel the boathouse, leave the motors and rudder assemblies in place at the rear of the boathouse foundation. Create trap doors in the flooring in important areas where the motor or steering assemblies are located. Then you will need to weld in flooring support braces across the width of the hull and cover it with marine grade plywood to create the flooring. Instead, use metal rails or connectors to create weld points. However, you should not pierce the hulls of the boats when welding them together. It is best to use even numbers of boats for greater stability (i.e. If you will use several smaller pontoon boats to create your foundation, you will need to weld the boats together. If you purchase used boats, you won't have this option, and finding matching pontoon boats may be difficult if you need more than one to form your foundation base. If buying new vessels, you should ask the manufacturer to leave out roofs, seating, upper rails, and other items you won't need. While larger pontoons or barges will be easier to work with, smaller types will usually result in a lower cost of construction with your new floating boathouse.

Also, you need to ask yourself if you want to purchase one large pontoon boat or a large Lash type pontoon or barge.

When thinking about pontoon boats to buy, you will need to choose between new and used vessels. You should also do some research on design types so that you can make better decisions as to the type of pontoon boat(s) you will need to buy. This will determine the size and number of pontoon boats you will need to purchase for the base of the foundation. Before you do anything, you should take the time to carefully consider how large you want your floating boathouse to be.
