12' Saturn Dinghy - Koopman Family OutingThe new 2020 model with our "Triton" series improvements (optional) are now in stock. 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 ($80 value), and an extended 3-year warranty ($100 value). The boat technical specifications are nearly identical between the Triton model (TR365) and our standard version (SD365). 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 12-foot inflatable boat SATURN SD365 has some great new upgrades that help improve the all around purposes this boat serves. The exterior rope/grommet line has been installed around the entire boat providing greater connection points and easier entry access from the water, the best part is that these features have been added at no cost upgrade to our customers! ($75 value)

It is still among our most popular tenders and also serves perfectly for a portable day use boat for ripping around your favorite watering hole. It comes with the most most rigid inflatable floor in the industry. The SD365 boats are longer and wider than our 11ft SD330 model, and can take up to a 30 HP outboard motor.

SD365 SATURN inflatable boats can be used for anything from a dinghy, to a fishing boat, to even a lifeboat or leisure boat. The SD365 boat is a large boat, but is still lightweight, and can be easily carried by one person with a wheel dolly. Great as a fishing boat too! Go boating without stretching your budget!

Saturn inflatable boats are made of 1100 denier Korean PVC fabric with polyester support that has excellent resistance to tearing, tension and breaking. It is a much more heavy-duty PVC fabric than most of our competitors with 1000 denier PVC boats.

2016 New 12' Saturn Inflatable Boat

With its’ simple setup, the 12' Saturn Dinghy Tender can have you and your family get off the couch and onto the water in minutes. It breaks down into a perfect size to fit in your truck and takes less than 10 minutes to inflate. Without the need for a trailer your family will love the extra space in the garage. Our custom drop stitch air floor is extremely rigid and is perfect for those looking for maximum portability.

To deflate the boat, simply open all air valves and start rolling the boat from the transom, or quickly suck all air out with an electric pump. Deflated, the SD365 boat will fold to the size of a large bag. Once deflated and folded, the SD365 can be easily stored in the back of a truck, SUV or even the trunk of a car. The provided carrying bag with deflated and packed boat can be easily carried with an inexpensive foldable hand cart. Inflated boat can be easily transported with the help of our removable dinghy wheels that can be attached to the transom.

Double layers of fabric at the bottom of the tubes and 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 boats chambers.


  • All around rope grab line.
  • Separate internal air chambers.
  • One-way drain valve with plug.
  • All around, durable rubber strike.
  • Safety valve to prevent over inflation.
  • Stainless steel D-rings for easy towing.
  • Reliable flat air valves with pushpin design.
  • Front bow D-ring with integral lifting handle.
  • Spare rope for attaching anchor is included.
  • Double layer of fabric at the bottom of tubes.
  • Holds up to 5 persons maximum or 4 comfortably.
  • Deep inflatable V-keel with a rub strake protector.
  • 24mm thick heavy-duty marine grade plywood transom.
  • Extremely rigid, lightweight hull for excellent performance.
  • Lightweight and strong removable aluminum seat benches.
  • Free second bench is included when order is placed on-line!
  • Equipment: aluminum oars, repair kit, seat bench and carry bag.
  • Free, high pressure high volume hand pump is included.
  • For the list of optional available accessories please visit our accessories section.

Features that further improve our inflatable boats durability and practicality:

  • Air valves have been moved toward the inside of boats tubes and away
    from direct exposure to the elements. This will allow easier inflation from
    inside the boat and will minimize damage caused by sun and rain while the
    boat is stored uncovered for prolonged periods of time. Rain water will not
    accumulate inside the valves.
  • Triangular symmetrical splash guards were installed on the transom
    corners to provide the sensitive transom of an uncovered boat with
    additional protection and shade from the elements throughout extended
    periods in Tropical environments.

Wow fantastic thanks for fast service!
I purchased my SD 365 3 years ago from you and have been extremely pleased. We have fished in the little boat from the far northern lakes of Northern Saskatchewan to the Sea of Cortez off Baja. I have a 9.9 Yamaha 2 stroke and it moves it along at about 15 - 18 miles per hour. I have a short shaft outboard but I added about a 1 inch strip to the top of the transom as I found the leg of the engine with the hydrofoil on was running too deep in the water at a plane. It helped to get the boat to plane easier. Our little boat has been portaged over Beaver Dams, run rapids in rivers, dragged across beaches in Mexico and only a few scratches. The only leak was in the air floor from a dropped fishing knife, no big deal to fix. I would strongly recommend your product to anyone who is looking for a good all round boat for all conditions.
The boat arrived a couple of days ago and it looks fantastic. I just tried it in a swimming pool and I love it. I already have the Saturn Proangler but this one is so much better with the oar rig and the transom. I will be able to do everything I want with this one.

It's very hot in Dubai at the moment. If I do manage to get out some early morning I will take a picture and send it to you.

Once again thank you for an excellent product and an amazing customer service.
I have a 12ft. boat w/a 25hp, that I purchased a few years ago (5/5/05) from your company. And I go crazy in it... I love it! I have jumped off boat wake in the bay behind my house: took it to Costa Rica and had it in the ocean with like 10 ft surf.....jumping them. Beach launched for spear fishing.....everything. But now the boat is still in Costa Rica and it is time for a new one. I have put that one thru hell. And one last thing, I don't think anyone has put your boats thru the things that I have. I have jumped it so high that I hit bottom and sear the motor mount (clamp) off. And I still haven't had a problem with it falling apart yet, besides a little delamination in the transom: and when I drive my boat I drive it to go as fast as I can...
I recently purchased a 12 ft. Saturn inflatable boat model SD365. This was an internet purchase, sight unseen. I pondered, shopped, and fretted for a month before taking the plunge. Specifically, I wanted an inflatable dinghy for my 36 ft. Mainship, which had no tender davit or even a really good place for one. The ability to bring the inflatable boat aboard, somehow, was very attractive from an operational standpoint. I've learned through several boat purchases over my lifespan that any boat you own only gets smaller with use. The maximum size that would not exceed the beam of my Mainship was the 12 ft. model SD365. I can single handedly roll this baby (120 lbs. wet) onto the swim platform davits that I installed. Launching the darling from this setup is as easy as untying your shoe. Initially I tried a 3.5 hp 4 cycle (38 lbs.) which was actually OK, except that it only had a 12 oz. self contained fuel tank. Fine, if you want ultimate portability and only want to run from anchor to the shore several times. Not fine, if you want to take your dink down the bayou (Biloxi, MS) to a dockside restaurant and back. Upped it to a 9.8, 4 cycle (89 lbs.) with a regular 3 gal. external fuel tank. Much better, except now I have to use a motor hoist instead of just doing it strong arm style. Always a tradeoff, yes? With the 9.8, and a self-installed planning fin, she pops up quickly and stays on plane at a relatively low speed. I like that. High speed performance with two aboard is adequate. I would have to guess...15 knots? Maybe 18. It's a guess. A rigid bottom would provide higher top speeds, but at a significant price and weight penalty. Hey, it's a dink!! I imagine a 15 hp motor would provide thoroughly satisfying top speed with two aboard. I just couldn't go the extra weight (115 lbs.). As with anything this light, passenger placement can have fairly dramatic effects. After a few experiments, and affirmations to my passenger regarding her dietary success, I found the correct configuration for both planning and cruise. The seaworthiness of the Saturn inflatable boat design has altered my thinking to the point that I'm certain I'll use her for fishing the offshore islands. Towing her behind my Mainship or on the swim platform should be a no-brainer. The BP oil spill will doubtless test her ability to withstand petroleum products. An update will follow once she's been exposed to that environment. I'm probably in for some kind of warranty breach there, I'm sure. Furthermore, I'm convinced that this thing just will not flip. YOU might fly out, so make sure that you wear your engine shut-off lanyard. When fun time is over and she has to get out of the pool, I've learned to open the valves, get off, and then I can haul her onto my back deck by hand. Please consider that I am 55 yrs. young, of slight build, and it is measurably a 12 foot lift from the water to the top of my deck rail. The fact that I can do it repeatedly, without going to the hospital, is a true testament to the portability of the design. I usually sit down for a cocktail shortly afterwards. I like to savor my accomplishments. And don't leave my inflatable boat in water for more than a week...barnacles.


Wise choice. I'm certain that there are comparable quality inflatable boats out there, but at this price...NOT! 12' Saturn inflatable boat is a good value and I'm the critical type. Glad I didn't go smaller. The inflatable floor works well and is lighter than the more complicated, and expensive, rigid floor. Maybe the motor mount could be a half inch higher, but what do I know. Being fairly well seasoned I have developed a skeptical eye, and don't give praise automatically. Saturn dinghy is well built. Seams and attachments appear to be top quality. This inflatable boat appears to be well engineered. I'm a commercial pilot and thusly aware of the trade offs that must be made between performance, utility, comfort, and price. The SD365 inflatable raft is excellent quality at an excellent price. Also, this is my first inflatable, so discovering that I can load 5 people plus 400 lbs. of gear is just mind boggling. It's the buoyancy factor. What a safety margin this thing possesses. My previous 14 ft. fiberglass skiff could hold 2 guys plus, maybe, a verbal message. The ability to take a 30 hp motor I find a little scary, but it speaks volumes about the capability engineered into this delightful, inflatable boat shaped, bobbing cork. I consider the bright red color to be an added safety bonus. It is exceptionally visible, even eye grabbing. Not getting run over by anything is highly desirable to me. At dockside, people (kids especially) think it is just plain cute. Strangers have asked if they could go for a ride to see what it was like. My inexperience with inflatables may have caused me to be a little cautious about inflation pressures. Evidently I was going too low because I ran into engine cavitation issues as well as a disconcerting floor deformation phenomenon. A passenger asked me if an orca was trying to surface underneath us. After reading through website's FAQ's it became obvious that I had merely under inflated everything. With only a modest pressure increase I had a properly performing inflatable boat. So you ask: Do you leave your 12 ft. Saturn SD365 on your big inflatable boat? Ummmm no, it's in a closet in my condo. It actually folded up and fit into the well designed canvas storage bag that came with it. Perhaps I've become jaded by years of marketing hype that usually fails to deliver as advertised. I just stood there and stared at it with incredulity after in fit on the first try. This kind of thing doesn't happen to me. Another cocktail and savor the accomplishment.

Regarding my Saturn inflatable boat I will say this: THE MORE I DO IT THE MORE I LIKE IT!
Hey, I just wanted to finally thank you for the awesome boat. I got the 12ft inflatable dingy with the air floor in January of 2010. This was a great solution for me. I live in an apartment and store the boat deflated on a trailer in my parent's backyard with a waterproof tarp over it. The neighborhood won't allow boats but since it sits on a small trailer, they don't even know it's a boat! Storability is the greatest advantage about this inflatable boat. Plus I plan on carrying the boat and outboard to the basement during the winter. I have gone out about 8 times this year and hope to go out a lot more next year. I would really recommend anyone to get some kind of hydrofoil for the outboard. They really do work, I gained 2mph, and the boat just feels a lot more stable. Turns are flatter and getting to plane is a quick process. Also check out my YouTube video below!
Hello, I received 12' boat that I ordered from you, and got to use it for the first time the other day. From the first time I inflated it, I have been amazed at the quality and construction of this boat. I expected a moderately decent boat with no frills, but this thing is awesome. I couldn't believe the bomb-proof construction of the tubes...they're rock solid, and the air floor is unbelievably comfortable, yet amazingly rigid. I put a 25hp outboard on it, and it is wickedly fast. It also easily smashes through 3 to 4 foot waves. I will be using it in the Gulf of Mexico in open ocean in a week or so, and I will be able to send you some pictures or video then. Please feel free to use anything I have said on your website, as I wish more people to know of your outstanding quality and service ...I wish nothing in return, except that you keep doing what you are doing. Your help and patience with my constant questions was very much appreciated...By the way, if anyone wants to know, the 12' inflatable with the air floor runs 28 MPH with a 25 hp outboard. That's with 2 people on board.
The Saturn 12 footer I bought from you is the most fun boat we've ever had over the last 35 years. It turns heads every time we're out on the water with it and folks always stop for a closer look at the boat ramp and ask a lot of questions about it. Another great thing to mention is how easy it is to paddle the boat in either direction! It just glides across the water. I also bought a 9.8 Nissan four stroke for this boat and swear you couldn't burn 3 gallons of gas in it in an entire day. Had to take it out in the ocean, just to try it out and it was more fun then I could ever imagine. Completely safe and super stable. Big boat wakes, in the Intercostals Waterway, are a snap with this boat! Ran it once, with just my 210 lbs in it, and it was scary fast! LOL! With the wife and I in it it runs about 16 - 18 knots at full plane using half throttle! Really and exceptional boat...
I purchased a raft from Saturn Rafts and due to several circumstances, there were some miscues and issues with the product fully working as designed. Rather than deny the product issue, the management of Saturn Rafts researched my particular boat and confirmed the anomaly. They stated that this was a 1 in a 1000 issue - but the thing I want to compliment them on is their 'commitment to customer satisfaction and making it right'. They did not try to hide when I contacted them and they followed through with an offer of a replacement boat or a full refund. I appreciate their honesty and customer service with a situation that could have been worse. I have a Saturn boat product today and am quite happy with it. These are quality individuals.
We purchased our Saturn Raft to take along with our boating group to Catalina Island, CA at the end of July. Were looking online and the nearest place to order was Idaho so we took a chance and we were not disapointed. Many people in our boating group are now thinking of purchasing their very own Saturn mainly for the size and durability. When returning from our week long trip to the island others boaters approached admiring our little boat asking where they could get one just like it. Our boat even made it to the front page of our boating website as you can see by the attached picture. We decided on red to match our sailboat and got comments about great color coodination and everyone wanted a picture..

This little very durable and we towed it along almost thirty miles from Long Beach, CA to Two Harbors, CA a trip that took us six hours in our little sailboat with the Saturn in tow. It held up and still looked the same upon arrival to island as when we left with the brand new boat. Had to make the trip back too which was also not a problem. This boat made a perfect tender for our week on the island. It fit easily into the dinghy dock for our multiple shore trips. Now we are planning to get a small motor although the paddles were great for rowing and met our needs. At the end of the trip it was nice to have a dry tender that fit nicely in the storage bag. We look forward to many more trips and adventures with the Saturn.
