Mako Boats 18 LTS Inshore 2011 vs Mako Boats 181 ST Inshore 2007 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Mako Boats 18 LTS Inshore 2011 and the Mako Boats 181 ST Inshore 2007 are modified vee designs with composite 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 18 LTS Inshore 2011 at 18,5 ft versus Mako Boats 181 ST Inshore 2007 at 18,0 ft. At 1 lbs and 99 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 18 LTS Inshore 2011 and 90 hp for the Mako Boats 181 ST Inshore 2007. 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 — 33 gal and 35 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Mako Boats 18 LTS Inshore 2011 is rated for 5 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 18 LTS Inshore 2011 could be the deciding factor.

Bottom line: Choose the Mako Boats 18 LTS Inshore 2011 if your priority is putting more people on the water — it handles 5 passengers and at 18,5 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.
