The Mercury 340 Air Deck White (Hypalon) 2006 vs Mercury 340 Sport Gray (PVC) 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Mercury 340 Air Deck White (Hypalon) 2006 at 11,0 ft versus Mercury 340 Sport Gray (PVC) 2006 at 11,0 ft. Weight tells a clearer story for trailering families: the Mercury 340 Sport Gray (PVC) 2006 tips the scales at 121 lbs — 110 lbs less than the Mercury 340 Air Deck White (Hypalon) 2006 at 11 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling — 15 hp for the Mercury 340 Air Deck White (Hypalon) 2006 and 15 hp for the Mercury 340 Sport Gray (PVC) 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 340 Air Deck White (Hypalon) 2006 comes in at 1 lbs per hp versus 8 lbs per hp for the Mercury 340 Sport Gray (PVC) 2006. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
