A pontoon bridge is a collection of specialized, shallow draft boats or floats, connected together to cross a river or canal, with a track or deck attached on top. The water buoyancy supports the boats, limiting the maximum load to the total and point buoyancy of the pontoons or boats. [2]
The fixed keel-equipped version of the boat has a draft of 4.67 ft (1.42 m), the shoal draft version has a draft of 2.00 ft (0.61 m), while the centerboard-equipped version has a draft of 3.50 ft (1.07 m) with the centerboard extended and 2.00 ft (0.61 m) with it retracted, allowing operation in shallow water or ground transportation on a trailer.

A soft inflatable boat (SIB) lacks the solid hull of a RIB and often has a removable slatted floor, so the boat can be deflated and transported in a car or other vehicle. Such boats have a low draft and are therefore useful for traveling across shallow water and beaching in places without landing facilities.
