Mako Boats 181 Inshore 2008 vs Mako Boats 181 ST Inshore 2009 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Mako Boats 181 Inshore 2008 and the Mako Boats 181 ST Inshore 2009 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Mako Boats 181 Inshore 2008 at 17,0 ft versus Mako Boats 181 ST Inshore 2009 at 17,0 ft. At 13 lbs and 13 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 — 90 hp for the Mako Boats 181 Inshore 2008 and 90 hp for the Mako Boats 181 ST Inshore 2009. 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. Both carry nearly identical fuel loads — 35 gal and 35 gal — so range won't be a tiebreaker here.

Both boats are rated for 4 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 Mako Boats 181 ST Inshore 2009 comes in at 0 lbs per hp versus 0 lbs per hp for the Mako Boats 181 Inshore 2008. 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: The Mako Boats 181 Inshore 2008 and Mako Boats 181 ST Inshore 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
