The Mercury 340 Air Deck White (PVC) 2006 vs Mercury V-570 White (Hypalon) 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.

Size is the most obvious dividing line here. The Mercury V-570 White (Hypalon) 2006 measures 18,0 feet overall (2006), giving it roughly 7,0 additional feet of deck space compared to the Mercury 340 Air Deck White (PVC) 2006 at 11,0 feet (2006). Weight tells a clearer story for trailering families: the Mercury V-570 White (Hypalon) 2006 tips the scales at 371 lbs — 362 lbs less than the Mercury 340 Air Deck White (PVC) 2006 at 9 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.

The power gap is worth calling out. Rated to 135 hp, the Mercury V-570 White (Hypalon) 2006 has a 120-hp advantage over the Mercury 340 Air Deck White (PVC) 2006's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Mercury V-570 White (Hypalon) 2006 is rated for 15 passengers, while the Mercury 340 Air Deck White (PVC) 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury V-570 White (Hypalon) 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 340 Air Deck White (PVC) 2006 comes in at 1 lbs per hp versus 3 lbs per hp for the Mercury V-570 White (Hypalon) 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.
