Explorer Attackaflat 2013 vs Explorer High-Side 2011 — Same Brand, Different Boat

Matching a modified vee Explorer Attackaflat 2013 against a tunnel Explorer High-Side 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Explorer Attackaflat 2013 at 18,0 ft versus Explorer High-Side 2011 at 17,0 ft. At 125 lbs and 75 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.

The power gap is worth calling out. Rated to 140 hp, the Explorer Attackaflat 2013 has a 40-hp advantage over the Explorer High-Side 2011's 100-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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 Explorer High-Side 2011 comes in at 1 lbs per hp versus 1 lbs per hp for the Explorer Attackaflat 2013. 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.

Bottom line: Performance buyers should lean toward the Explorer Attackaflat 2013 and its 140-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Explorer High-Side 2011 with its 100-hp rating is the more economical daily driver.

Explorer Attackaflat 2013 vs Explorer High-Side 2011 — Common Questions

Which is the larger boat — the Explorer Attackaflat 2013 or the Explorer High-Side 2011?
The Explorer Attackaflat 2013 is the longer of the two at 18,0 feet overall. The Explorer High-Side 2011 comes in at 17,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Explorer Attackaflat 2013 or the Explorer High-Side 2011?
For trailering, the Explorer High-Side 2011 has the edge at 75 lbs dry weight versus 125 lbs for the Explorer Attackaflat 2013. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Explorer Attackaflat 2013 is rated to a maximum of 140 hp, giving it the larger power ceiling. The Explorer High-Side 2011 tops out at 100 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Explorer Attackaflat 2013 is Coast Guard rated for 5 passengers, while the Explorer High-Side 2011 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The Explorer High-Side 2011 has a better power-to-weight ratio at 1 lbs per hp compared to 1 lbs per hp for the Explorer Attackaflat 2013. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Explorer Attackaflat 2013 measures 96" wide, compared to 88" for the Explorer High-Side 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Explorer Attackaflat 2013 and Explorer High-Side 2011 from the same manufacturer?
Yes — both the Explorer Attackaflat 2013 and the Explorer High-Side 2011 are built by Explorer. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
