works great. the seat location isn't perfect for me (6'1) or my son (5'10). the oars kept hitting our knees, maybe we're doing it wrong. Super easy to set up and get going. Using the supplied pump didn't take long to inflate all 4 chambers. The connection onto the pump came off a few times. Fairly light, we were able to carry it about 100 yards to a pond to try it out. No leaks yet. I'm going to build a PVC dolly to make it easier. I may get a trolling motor one day just to make it more relaxing to get around. Overall, I'm happy with my purchase.

I love my sk407xl ...Been out 6 times fishing and just cruising, is super stable im 240 pounds and i can stand and cast on it . Have loaded with about 600 pounds and my suzuki 9.9 pushes it at 18mph it handles good i recomend you buy a electric pump to cut the inflation time in half and your arms wont be sore. Takes me 30 min with the hand pump to inflate all five chambers to spec. Get wheels too thay are a must for launching if you dont have help.

Lots of space, very sturdy. I cant find anything to complain about.

Ordered the 15’ KaBoat SK470XL. Boat was priced below any other competitors was shipped promptly and arrived within a few days. Washer on pump was installed incorrectly which took time to figure out why pump did not work but once we found problem everything worked. Missing one set of oars but B2G is sending missing items.

Took boat on maiden voyage and it exceeded expectations. Very well made and perfect for what we need. Look forward to several years of use. Thanks!

I have owned my Kaboat for 3 years now. Absolutely love it. The quality of the boat is well made. I use a Yamaha 6hp short shaft four stroke on it. It has a speed prop and would push the boat 22mph on a flat lake burning .5 gal an hour. With my three gallon tank, I could run WOT for six hours, giving me a range 120+ miles on a three gallon tank! Very impressed with the boat. I have used in on the Susitna River, handles well in fast flowing rivers. Packs right up for airlines and small bush planes. Super fun boat when packed lightly. I am going to try and find a lightweight 15-20hp two stroke next. Also building a raft frame for it so it can be rowed with larger oars and accommodate a larger outboard.

I’ve owned my Alaskan series kaboat now for three seasons. I’ve ran 3 different outboards on it. Started with a 7.5 hp 2 stroke mercury that was pushing myself and a friend with our hunting gear (800 lbs of stuff) at 8 to 10mph depending on water conditions. I was ok with the speeds but wanted to go with a lighter motor so I bought a 2.5 hp Suzuki 4 stroke. I was only getting 6 mph empty and I was not impressed with the speed from this smalle outboard, though it could have been quiet and useful in a fly in trip. I went back to my 2 stroke and used it on a 4 day hunting trip. The max speed I got with a smaller hunting partner was 8.5 mph and that was after stashing all our extra gas. It took us over 8 hours to complete our round trip (launch to camping spot and back) and we burned a little over 6 gallons of gas. It was frustrating. Not sure if I need a new prop or if the motor is just dying. Anyways, I decided to buy a new tohatsu 20hp. This motor weighs 95lbs, which is rhw same weight as the 9.9 from Honda or Yamaha and it was only $400 more than the tohatsu 9.9 hp. Don’t worry, I have no desire to go faster than 20 mph (which I was getting at just a little more than 1/2 throttle. I also cut my 8 hour round trip into a 3 hour round trip that burned a total of 3 gallons of gas (had a three gallon tank hooked up and full). I didn’t have to swap my gas tank out and I still had a little in the tank. I gps’d my trip and reached 23mph a couple of times when the lake was flat. I felt comfortable, though I wouldn’t want to go faster. We had about 700 lbs in the boat too.

I send you some Pictures from Summer time in Croatia.

With new engine 9,9 Hp- Tohatsu I ‘have reached 35 km/ h . Really fast J

Just wanted to tell you about how much I am enjoying my SK470XL KaBoat! As soon as I signed for the box, I brought it down the basement and unpacked and inflated it! I immediately began planning places to take it! I deflated it and packed it away till the next weekend. First trip was down to the canal with the kids The boat was sturdy and felt good in the water. I was impressed yet again. The 55lb thrust electric motor pushed it nicely! We had a good time with no issues… Second trip was a solo on a big slow moving river, fishing for pike. I had no problems with the setup or break down of the boat. I received a lot of compliments on the new ride! My third trip was a camping trip on a deep reservoir. Packed with 500lbs of weight, my KaBoat handled perfect with the 6HP outboard.. I reached 12 mph in semi calm conditions.. Once again, the KaBoat proved itself to me as a reliable, fun, and safe new toy! Next trip will be some saltwater back-bay action! Thanks for a great product...

19 MPH with 2 people 9.8 HP Nissan 4 stroke. 6 mph at 1/3 throttle of my 2.5 hp Suzuki 4 stroke. Been pretty impressed with mine thus far. Used it out in snowy PWS last week for 6 days. Was able to get 6 mph at 1/3 throttle of my 2.5 hp Suzuki 4 stroke and 7.2 at WOT. Burn under 1/2 gallon and went approx 23 miles according to the GPS on it...pretty affordable little rig to run for sure! Got the new 6 hp Merc 4 stroke on the Kaboat yesterday and today....WOT is 14 mph with me and Mrs. 1/2 throttle is about 11-12, 1/3 throttle is around to be going 8.5+ to stay on plane it appears. Much happier with this little motor than the 2.5...getting on plane will make up any loss in extra fuel burned by the 2.5 by being on top the water and going faster than doing the 6 mph push through the water at 3/4 throttle in the 2.5. Also like that its still only 55 pounds and I can easy get on step with it. Fun little boats indeed!
