The marine tower kit is specifically designed to aid mounting the turbine on a boat deck.
Kit includes vibration damping mounts, and all necessary marine grade hardware to install the kit.
You need to supply the 1.5" sch40 steel or aluminum pipe and two 1" OD stays, which will be available at your local fence company or marine fitter. Alternatively, you can purchase the TOW-MARINE-9FT kit which includes a 9ft tall powder-coated aluminum mast with two 9ft stays.
