Solid aluminum frame, heavy duty floats, cedar decking. Total of five sections 4’x 8’ plus one section 16’x3’ gangway. I used this as a touch and go dock in the Merrimack River, at high tide there was 6’ of water unite the dock, at dead low tide it would sit flat on the beach. Also would be great for a lake. Two sections bolt together to make an 8’x8’ swim platform set the end, then 3 sections bolt end to end for 24’ length and connect to the 16’ gangway which would connect to your landing platform. All together with the swim platform configuration the length is 48’. The dock is not launched, is on land waiting for your pickup. (Rowboat separate, $250)
