Mako Boats 181 ST Inshore 2007 vs Mako Boats 2201 Tunnel Inshore 2011 — Same Brand, Different Boat

Matching a modified vee Mako Boats 181 ST Inshore 2007 against a tunnel Mako Boats 2201 Tunnel Inshore 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.

Size is the most obvious dividing line here. The Mako Boats 2201 Tunnel Inshore 2011 measures 21,3 feet overall (2011), giving it roughly 3,3 additional feet of deck space compared to the Mako Boats 181 ST Inshore 2007 at 18,0 feet (2007). At 99 lbs and 21 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 225 hp, the Mako Boats 2201 Tunnel Inshore 2011 has a 135-hp advantage over the Mako Boats 181 ST Inshore 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Mako Boats 181 ST Inshore 2007 carries 35 gallons versus 6 gallons in the Mako Boats 2201 Tunnel Inshore 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Mako Boats 2201 Tunnel Inshore 2011 is rated for 8 passengers, while the Mako Boats 181 ST Inshore 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mako Boats 2201 Tunnel Inshore 2011 could be the deciding factor.

Bottom line: Choose the Mako Boats 2201 Tunnel Inshore 2011 if your priority is putting more people on the water — it handles 8 passengers and at 21,3 ft it has the deck room to back that rating up comfortably. The Mako Boats 181 ST Inshore 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

For trailering, the Mako Boats 2201 Tunnel Inshore 2011 has the edge at 21 lbs dry weight versus 99 lbs for the Mako Boats 181 ST Inshore 2007.
