The Mercury 320 Ocean Runner White (Hypalon) 2006 vs Mercury 380 Heavy Duty Hypalon 2011 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 380 Heavy Duty Hypalon 2011 measures 12,5 feet overall (2011), giving it roughly 11,5 additional feet of deck space compared to the Mercury 320 Ocean Runner White (Hypalon) 2006 at 1,0 feet (2006). At 182 lbs and 233 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 15 hp for the Mercury 320 Ocean Runner White (Hypalon) 2006 and 25 hp for the Mercury 380 Heavy Duty Hypalon 2011. 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.

For family outings this is probably the sharpest distinction between the two. The Mercury 380 Heavy Duty Hypalon 2011 is rated for 6 passengers, while the Mercury 320 Ocean Runner White (Hypalon) 2006 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury 380 Heavy Duty Hypalon 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 380 Heavy Duty Hypalon 2011 comes in at 9 lbs per hp versus 12 lbs per hp for the Mercury 320 Ocean Runner 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.
