Inflatable Boats · Reviews
11′ of inflatable boat, room for 4 adults plus 1 child, rated up to a 15 hp (15″ shaft / 125 lbs) outboard. Here is an honest, spec-by-spec look at the SD330W — what it does well, what it costs, and who it is actually for.
The 11' Inflatable Boats SD330W is an 11' inflatable boat from Saturn, built for boaters who want a real boat that still packs into the back of an SUV. It is rated for 4 adults plus 1 child with a 1400 lbs load capacity, which covers a realistic day on the water for most buyers.
At 11', it is the 12th smallest of the 26 inflatable boats in Saturn’s current range. At $1,099, it lands in the middle of the pack on price. If you want to skip ahead, check the current price here.
For this review I went through the full spec sheet line by line, so everything below comes from what the manufacturer actually publishes — dimensions, capacities, and construction — plus what those numbers mean once the SD330W is on the water.

On the Water
On the water, three numbers tell you most of what you need to know: length, beam, and tube diameter. At 11' long and 6.1' wide with 17" tubes, the SD330W is a mid-size inflatable with a reassuring footprint. In inflatables, tube diameter and beam do most of the work keeping you level — wide tubes are why these boats feel so much more stable than their weight suggests.
The transom is rated for up to 15 HP (15" shaft / 125 lbs). That keeps you in small-outboard territory — light, affordable motors that one person can lift and mount. That is the whole point of a boat like this: enough power to get you to the spot without the cost, weight, and upkeep of a big rig.
Saturn lists a speed of 17 mph (10HP w/2 adults). Treat that as a realistic expectation with the stated setup rather than a promise — load, prop, and conditions move that number around.
Plan around the 1400 lbs load rating, not just the person count. Add up people, motor, fuel or battery, cooler, and gear before you buy. If that math lands close to the limit, size up — a boat that runs near its rating is slower, wetter, and less fun.
Build and Materials
The tubes are 1100 Denier Reinforced PVC. That is the heavy-duty end of the PVC fabrics used on inflatables this size — thicker fabric resists abrasion and holds air pressure more consistently. Seams are Quadruple Overlap. More overlap at a seam means more glued surface holding the tube together, which is exactly what you want on a boat that lives in the sun and gets dragged up beaches.
The spec sheet lists 3+1+1 air chambers. Separate chambers are a safety feature, not a spec-sheet decoration: if one compartment is ever compromised, the others keep you afloat. The Recessed One-Way valves sit flush in the tubes, so there is nothing sticking out to snag on a dock, a truck bed, or your fishing line.
The Drop Stitch Air Floor inflates drum-tight and gives you a rigid deck to stand on. If you fish standing up — sight casting on flats is the classic case — a hard-feeling floor changes the whole experience.
Weight, Portability, and Setup
The SD330W weighs 110 lbs. Plan on two people or a dolly for the carry to the launch. It packs into a 53x26x15" package (132 lbs).
BoatsToGo does not publish a setup time for this model. For an inflatable this size, plan on 15–20 minutes with a decent pump the first few times; it gets faster once you have done it a couple of times.
Who It's For — and Who Should Skip It
Who it is for: anglers, divers, and families who need a tender — or a standalone fishing boat — without owning a trailer, running up to a 15 HP (15" shaft / 125 lbs) outboard. If your fishing looks like trailer-free launches, skinny water, and packing the whole rig into a vehicle, the SD330W fits the program.
Honest trade-offs: it is still an inflatable, so inflation and setup are part of every trip. Sharp shells, hooks, and rocky shorelines demand the same respect you would give any PVC boat. Rinse it after saltwater use and store it out of long-term direct sun — UV is the slow killer of every inflatable ever made.
Who should skip it: if you want to turn the key and go with zero setup, or you regularly run rocky rivers, a rotomolded or aluminum hull will make you happier.
How It Compares
Within Saturn’s current range, the next step down is the 11' Inflatable Dinghy Boats SD330 (11 ') at $899 and the next step up is the 11' Professional-Grade Boat SD330PRO (11 ') at $1,269. If you are torn between sizes, the usual advice holds: buy for the load you will actually carry most weekends, not the biggest crew you might take once a year. A smaller boat that runs light is faster, drier, and easier to handle than a bigger one loaded to its limit.
Care and Maintenance
An inflatable boat rewards basic care and punishes neglect — the good news is the care part is simple. Rinse it with fresh water after saltwater use, and let it dry before you roll it up; packing a damp boat away is how mildew starts.
Watch air pressure when temperatures swing. Air expands in the heat and contracts in the cold, so a boat inflated drum-tight on a cool morning can get very firm by midday. Bleed a little air if the tubes feel overly hard, and top up when evenings cool off.
For storage, keep it out of long-term direct sun — UV is the slow killer of every inflatable — and store it loosely rolled or partially inflated rather than folded tight on the same creases every time. Keep sand and grit out of the valves, and carry a small patch kit aboard. None of this is difficult; it is just the routine that keeps an SD330W going for years instead of seasons.
