Inflatable Boats · Reviews

12′ of inflatable boat, room for 5 people, rated up to a 25 hp (15″ shaft / 130 lbs) tube outboard. Here is an honest, spec-by-spec look at the FB365 — what it does well, what it costs, and who it is actually for.


The 12' Heavy-Duty Boat FB365 is a 12' 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 5 people with a 1300 lbs load capacity, which covers a realistic day on the water for most buyers.

At 12', it is the 12th largest of the 26 inflatable boats in Saturn’s current range. At $1,559, it lands at the premium end 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 FB365 is on the water.

Key Features

  • 12' long × 60" wide
  • 16.5" tubes
  • 3+1 air chambers
  • Rated for 5 people
  • 1300 lbs maximum load
  • Transom rated up to 25 HP (15" shaft / 130 lbs) Tube
  • Packs into 45x26x16" Tube
  • High Pressure Air Deck Floor

On the Water

On the water, three numbers tell you most of what you need to know: length, beam, and tube diameter. At 12' long and 60" wide with 16.5" tubes, the FB365 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 25 HP (15" shaft / 130 lbs) Tube. 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.

Plan around the 1300 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 spec sheet lists 3+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 High Pressure Air Deck Floor keeps weight down while still giving a firm surface underfoot — a good middle ground between a rigid floor and a basic fabric bottom.

Weight, Portability, and Setup

It packs into a 45x26x16" Tube package (125 lbs). The packed bag fits in most car trunks or SUV cargo areas — no trailer, no roof rack, no storage unit.

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 25 HP (15" shaft / 130 lbs) Tube outboard. If your fishing looks like trailer-free launches, skinny water, and packing the whole rig into a vehicle, the FB365 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 12' Inflatable Budget Boats CB365 (12 ') at $699 and the next step up is the 12' Fishing Inflatable Boats FCB365 (12 ') at $799. 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 FB365 going for years instead of seasons.
