18' SATURN SD518 inflatable boats are made from heavy-duty quality PVC fabric, and can handle up to a maximum of 10 persons.  

Deflated, the SD518 boat will fold to the size of one large and heavy bag with tubes and another large and heavy flat bag with a floor. Once deflated and folded, the SD518 inflatable boat can be stored in the back of your SUV or minivan, large closet of your apartment or in a garage.

Double layers of  fabric at the bottom of the tubes and a rub-strake protector along the keel provide extra protection from sharp rocks and abrasive sand. The safety valve will prevent excessive air pressure in the boat's chambers.

* Specifications and accessories are subject to change without notice. Max O/B Motor means: maximum power of outboard motor that can be safely used to plane the boat loaded to the maximum capacity at normal water surface conditions. Please exercise common sense and caution when using maximum motor capacity. Do not jump from wave to wave as new 4-stroke motors are much heavier then 2-stroke and provide extra strain on the transom. Under normal circumstances, with half the maximum persons/load capacity, 50% of maximum O/B power rating may be necessary to put boat on plane.

Quick Tip! Worried about the heavy weight of a hard floored boat? Don't break your back! Get a foldable hand cart from any retail store to carry the folded boat around. Even inexpensive dolly movers will work great for transporting a folded or fully inflated boat. Get dinghy dolly wheels to easily move the inflated boat across the shore and into the water.
