This is a new color for Saturn and exclusive to Alpine Boats

This new and revolutionary product is a crossover between an inflatable kayak and an inflatable boat - KaBoat! It can be used as a regular kayak, just paddling anywhere you want, ocean, bay, river or lake. If you get tired, use an electric or gas engine installed on the marine grade plywood transom.

The 15' SK470 provides maximum space and comfort due to the larger distances between the aluminum seats and extra space in the front bow area. Its high buoyancy provides support for more cargo and passengers.

Use the KaBoat as an inflatable boat with an outboard engine. It can take up to a 10 HP gas outboard engine or portable electric motor! If the battery charge or gas is low, then use as a kayak to paddle to your destination. You don't really need that big of an engine, even with a 3.5 HP engine this boat will fly at 15-20 mph with 2 people. See the video clipsbelow. Also tested to run nice and quite with an electric engine with speeds of around 5-7 mph and runs 2-3 hours at full speed. You can also put an electric engine on at minimum speed to run for up to 6 hours, and use it as a "ride assist" while kayaking with paddles to your destination far away.

The all new SK470 KaBoat now comes with 2(two!) sets of oarlocks in order to select the best rowing position, or for attachment of optional second set of oars for tandem rowing. However, it still can be used as a kayak when navigation is narrow or shallow.

The KaBoat is extremely portable and will fit in a medium size bag. Now you can go on vacation and take the KaBoat with you! The main benefit is that if you get tired of paddling you can use the engine to get back ashore.

The KaBoat can also be used as a dinghy for yachts or sailboats to get ashore from the mainship. It is portable and takes up much less space then a regular dinghy.

The KaBoat's exceptionally stable design allows you to stand, fly fish or even get into those narrow spots where other boats can't go to get to the best fishing. Aluminum seats provide excellent support and can be customized by drilling holes and installing folding fishing chairs with a swivel base, or canoe seats for additional back support on long trips.


Benefits of KaBoat VS. conventional Kayak or Inflatable Boat:

  1. Conventional plastic or fiberglass kayaks require significant storage space due to their large dimensions. KaBoats can be deflated and folded for easy storage and transportation. 
  2. Kayaks can be only paddled, but the KaBoat allows you to use a small gas or electric engine to cover larger distances. If you get tired of paddling, you can start using an optional outboard engine.
  3. KaBoats are much more stable than conventional kayaks, allowing for standing and walking inside the KaBoat. In fact, you can fish standing or even ride while standing.
  4. The KaBoat can be used for diving, snorkeling, and fishing, however not many conventional kayaks can offer similar functionality.
  5. Due to the high buoyancy of its inflatable tubes, the KaBoat can transport a much larger cargo than regular kayaks. 
  6. KaBoat allows you to go to narrow or shallow places where regular inflatable boats will not fit. Just raise the engine and paddle anywhere that is at least 5" deep.
  7. Due to its smaller chambers, it is much easier and faster to inflate a KaBoat than a regular inflatable boat.
  8. Because of its narrow profile and a much lower drag than wide conventional inflatable boats, KaBoats can go faster with the same rated engine than comparable size inflatable boats.
  9. KaBoats can also be used as a dinghy to a yacht or sailboat, but take up much less space when deflated and folded. KaBoats also can be placed on a swimming platforms.
  10. KaBoats cost much less than any inflatable dinghies and most kayaks available today.


Most recent customer's reviews of Saturn SK470 KaBoat:

"Your boats are GREAT - making 10 mph (controlled by Garmin GPS) with 2 peoples on 2.5HP Suzuki outboard!" Alex, Ontario, Canada

"Just wanted to tell you how much I love my 15 ft Kaboat. I get compliments wherever I go. I fish it in both freshwater and salt and it has performed wonderfully. Very stable, safe and fun. After seeing my boat in action, no one I know wants a canoe anymore.... The best part is: completely portable and no maintenance!!!! What's not to love? I keep it in the backseat of my Ford Taurus. Whoever designed it should get the Nobel prize for boat design. I put a 3 HP mercury on it and it really moves. Just can't say enough. Thanks Boats-to-go!"

"I got an Sk470 15' Kaboat a couple of months ago. This is my first and only boat, primarily to be used for fun around the harbor in my town on Long Island. Since it is my first and only boat, I had a bit of a learning curve. I quickly learned that boats are not the water equivalent of cars. Many more dynamics requiring many more considerations.."
