2016 Model 18' Saturn DinghyThe new 2020 model with our "Triton" series improvements (optional) are finally here. The Triton Series upgrades represent over $400 additional value and include; upgraded PVC construction ($75 value), heat-welded seam technology ($150 value), C7 style inflation valves ($120 value), and an extended 3-year warranty ($100 value). The boat technical specifications are nearly identical between the Triton model (TR518) and our standard version (XHD518). These Triton series improvements incorporate the newest technologies in inflatable boat construction and provide an incredible value for those looking to put their boat to the test. If available, this option will be listed under the "Model" selection.

The all new 18' Saturn Triton Series 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 Saturn SD518 is a beast! This 18 foot inflatable monster is really incredible. My buddy and I split the cost, and now we take our two families out on this thing together almost every weekend. Our kids are friends, and our wives are close, so it gives everyone an excuse to get together. Plus, my buddy and I don’t mind the fishing we get to do.

This rubber boat is so big, we can fit both our families, all our fishing gear, and plenty of food and drink. Even some adult beverages! It all fits right in the bed of my truck, so it’s easy to get to and from the water. And between the two of us, carrying it down to the shore isn’t any problem at all. Next I think I’m get a smaller inflatable boat from you guys for those times when I can get a day by myself. Not that that happens too often nowadays.
