BEFORE ORDERING – Check with your local building/zoning authorities and neighbourhood association for permits and other requirements.

A Multinautic® dock system is a simple way to expand your outdoor living space! This complete dock/ramp hardware kit is made from marine‐grade hot‐dip galvanized steel and premium foam filled floats, and will allow you to easily assemble a wooden semi‐floating dock or ramp. The unit can be installed with a high freeboard floating dock (Costco Item# 204934) and/or a fixed dock (Costco Item# 204884) for a complete dock layout. Whatever your waterfront requires, Multinautic® has the dock to accommodate those needs. This dock RAMP KIT will give you a smooth transition between shoreline and dock, and because one extremity is supported /anchored to shoreline, while the other extremity is on floats, it will automatically adjust to water level fluctuations of up to 3’ (this kit can also be converted into a full floating dock, by simply ordering 2 additional R-600 floats and some more wood supports).  NOTE:  For LOWER Freeboard Ramps & Docks, great for canoes and kayaks, please check out our other dock kits on this website.  Designed to be both sturdy and long‐lasting, a Multinautic® docking system will provide years of enjoyment!
