The all new 2019 18' Saturn Inflatable Boat (SD518) is our largest vessel and was designed for rugged commercial and private use including commercial fishing/crabbing, fire department and coastguard activities, and military operations. The heavy-duty design includes three exterior air chambers, extra bouyant 20" diameter exterior tubes, thick rub strake material, a reinforced yet lightweight aluminum 6-piece floor, and increased passenger/gear capacity (it can accommodate up to 10 passengers!)

Deflated, the SD518 boat can be stored much more easily that any RIB or rigid floor product. The tubes, transom, and bottom floor covering will fold together to store in a wardrobe sized nylon bag and the floor can be easily broken down and stored separately into the included zippered bag.

Extra thick multiple PVC/fabric layers reinforce the bottom of the tubes and a rub-strake protector along the keel provides extra protection from sharp rocks and debri. The pressure relief valve in the exterior tubes will prevent excessive air pressure.  The exterior rope and multiple d-rings allow for all types of add-on components including sun shade bimini tops, rescue features, storage bags, etc.


The 18' Saturn Inflatable SD518 boats come equipped with with a sectional heavy-duty aluminum floor for maximum rigidity and minimal weight. The bow section is made of a marine grade plywood floor covered with a gray resin.
