Killer Whale 10.8′ Inflatable Fishing Boat | Aluminum Floor Dinghy

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.
