Matching a flat Explorer Flatsmaster 2011 against a tunnel Explorer Tunnel Vee 2013 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.
Size is the most obvious dividing line here. The Explorer Tunnel Vee 2013 measures 17,0 feet overall (2013), giving it roughly 3,5 additional feet of deck space compared to the Explorer Flatsmaster 2011 at 13,5 feet (2011). At 7 lbs and 8 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 100 hp, the Explorer Tunnel Vee 2013 has a 40-hp advantage over the Explorer Flatsmaster 2011's 60-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 Explorer Tunnel Vee 2013 is rated for 5 passengers, while the Explorer Flatsmaster 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Explorer Tunnel Vee 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Explorer Tunnel Vee 2013 comes in at 0 lbs per hp versus 0 lbs per hp for the Explorer Flatsmaster 2011. 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: Choose the Explorer Tunnel Vee 2013 if your priority is putting more people on the water — it handles 5 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Explorer Flatsmaster 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
