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.
Soft inflatable boats are available with several floor choices: Roll up slat floor Hard floor made of fiberglass, aluminum or wood panels Ribbed air floor (on inflatable rafts) High pressure air floor
