Description
Description
The Island Hopper Killer Whale 10.8′ is the aluminum floor version of the flagship inflatable fishing boat — built for buyers who want the rigidity, durability, and permanent feel of a hard-hull RIB without the dock, the trailer, or the six-figure price tag. Where air floor models need pressure checks and re-inflation, the Killer Whale's aluminum deck is always solid, always ready, and handles everything from SCUBA tanks to anchor chain without a second thought.
Rigid Aluminum Floor System — Never Re-Inflate:
The Killer Whale ships with a heavy-duty aluminum floor system: 5 interlocking floor pieces and 4 aluminum side rail stabilizers that lock together to form a rigid, flat deck. Unlike a drop-stitch air floor, the aluminum deck requires no inflation, no pressure monitoring, and no re-pumping between uses. It is the preferred choice for live-aboard sailors, dive operators, and anyone who leaves the boat inflated year-round in the environment or uses it daily over an extended season.
Military-Grade PVC | Fresh and Salt Water Rated:
Built from heat-welded PVC with a reinforced .9mm, 1100-denier rip-resistant fabric shell — the same construction standard across the Island Hopper inflatable fishing boat lineup. UV-resistant, oil-stain-resistant, and puncture-resistant in fresh and salt water. The V-shaped hull and 3-bow mooring D-rings deliver real directional stability, while extended rear pontoons improve buoyancy and planing performance with heavy loads aboard.
5-Person Capacity | 15HP Motor Ready:
Supports up to 5 people and 1,268 lbs. The reinforced transom handles motors up to 15HP (15 inch short shaft recommended; 20 inch long shaft compatible), accommodating both 2-stroke and 4-stroke outboards for fast planing speeds in fresh or salt water. Comes with 2 aluminum oars and lock-in oar holders. Optional EVA teak foam decking ($129) adds a slip-resistant surface over the aluminum floor for added stability and comfort.
Aluminum Floor vs. Air Floor — Which is Right for You?
Choose the Killer Whale aluminum floor if: you store the boat inflated for extended periods, you carry sharp gear (SCUBA tanks, anchors, weight belts, dive knives), you have pets aboard, or you want zero maintenance between uses. Choose the Swordfish air floor if: you prioritize lighter weight when deflated, you want the integrated EVA teak deck as standard, or you inflate and deflate the boat for each use. Both models share the same hull size, motor capability, and USCG approval.
USCG Approved | Complete Kit | 3-Year Warranty:
Ships USCG approved with a Manufacturer Certificate of Origin for official boat registration. Complete kit includes: 1 aluminum bench seat, removable seat cushion with storage bag, 2 aluminum oars with lock-in holders, carry bag, high-pressure PSI foot pump, and repair patches. Backed by Island Hopper's 3-year limited 'No Seam Blowout' manufacturer warranty. One purchase, fully water-ready.

The killer whale 10.8ft boat is very reliable and well constructed. it out preforms other brands with construction and quality. I'm on the water for weeks to months at a time. You can depend on this boat when it really counts.
Awesome boat! Rugged, stable and easy to put together! Light enough Kel and I can load/unload it. The floor makes all the difference with our dog. Wife and lab approved! Don't hesitate, order today! And ask for Eric!
We purchased the Killer Whale to replace our 12 year old Achilles. We took it on our maiden voyage on a windy day along the south end of the Detroit River/ western Lake Erie. The boat handled the rough water beautifully and with two adults it easily got on plane with a modified 9.9 Mercury. We were originally really impressed with the boats specs, and made our final decision to purchase this vs others that were similar due to the thickness of the floor boards and seat. The specs list the thickness as 24mm, which is false, the thickness is the same as other brands & only 12mm. The boat is actually 11'2" not 10'8". We ordered the additional storage bag which was not in the box when delivered. Eric at SB contacted us immediately to let us know it was being mailed. The company was awesome as far as answering questions and knowing their product. The transaction was an easy purchase and to register in Michigan. All in all we are very pleased with the boat, I would highly recommend and would purchase again.
Fantastic inflatable! Bought it last summer for use in Maine running between Islands. Incredibly stable, not afraid to take it anywhere. Customer service was or has been awesome. Putting floor in is much easier with two people.
Excellent boat and customer service
My Killer Whale 10.8' - Model 330 has been an excellent tender for my sailboat. The aluminum floor is a great feature offering stability and a solid feel to to the boat. Their customer service is very responsive. They produce a Bill of Sale and a Certificate of Origin a year after I bought it which was needed to register the boat in my state."
I bought the Killer Whale and added a 9.9 HP Mercury as my dinghy on a 53' Hatteras. Due to river flooding, I had to use it right away to ferry provisions and was very pleased. It can carry quite a bit. One note to make is that it only comes with one seat, even though most of the pictures show two. I will buy the additional seat, but wish it had been more explicitly stated so that I could have bought it when I ordered the boat. Overall though, I am very happy with the purchase. Packaging and delivery was great. Installation wasn't too bad, make sure you don't inflate it too much prior to installing the floor.
We have owned many dinghys over the years [Avon, Zodiac, Walkers Bay, etc.]. We own an Inflatable Sports Killer Whale 10'8" and are very impressed with the quality and design. The designers obviously put a lot of thought into this boat-from the placement of the carrying handles to the quality of the aluminum floor to the heat-welded seams. It was easy to assemble and easy to put away. It planed very easily with a 9.8 Tohatsu with an additional load of 450#. So far, this is the best dinghy we have owned. Customer service has also been very helpful. Very nice.
Got the Killer Whale in early July and have used it 6 times. We live on the South Shore of Long Island NY. Added a 9.8 Tohatsu and this makes a perfect combination for fishing, crabbing or just plain cruising. Boat is very stable, planes easily and quite roomy not to mention standout good looking. I highly recommend the boat to all sightseers that stop over to look at it. PS: I put the Newport 11 foot cover on it and fits like a glove.
I recently purchased the Killer Whale and matched it up with a Mercury 9.9 hp engine. This boat is very nicely built and the standard equipment is impressive. At full throttle it hits 20 mph which is quite fast on a small boat. I had some issues getting the trim and weight distribution correct in order to plane with two people and the customer support was absolutely awsome. I love this boat and, if you have had other boats with trailers and storage fees, you will save lots of money over time. I also want to mention that you will feel safer compared to a similar size aluminum boat because are can't swamp this boat in large waves. When taking longer jonts, we don't worry about the weather getting bad, we just take it slow. You won't be dissapointed!!!
