<p>A floating walkway or marina (16) is made from pontoons (10) each comprising a deck (11) beneath which is positively located a float (12) to support the deck (11). The pontoons (10) are coupled together and fingers (22) extend from the pontoons to provide moorings for vessels. The fingers (22) each include a deck (11') and floats (12') positively located beneath the decks (11'). Each float (12 and 12') has a thin lightweight protective coating. The coating can be selected from the following: (i) an open weave mesh fabric; (ii) a glass fibre reinforced polyester; (iii) an acrylic cement; (iv) a flexible deformable membrane; or (v) a spray urethane and the coating can be up to 5 mm thick. The floats can be contoured to enhance laminar flow of water about the submerged portion of the float.</p> |
