When two boats share the same hull type — in this case both the Mako Boats 1901 Inshore 2007 and the Mako Boats 191 Inshore 2007 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 1901 Inshore 2007 at 18,0 ft versus Mako Boats 191 Inshore 2007 at 19,0 ft. At 17 lbs and 15 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 175 hp, the Mako Boats 191 Inshore 2007 has a 25-hp advantage over the Mako Boats 1901 Inshore 2007's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 47 gal and 47 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Mako Boats 1901 Inshore 2007 is rated for 7 passengers, while the Mako Boats 191 Inshore 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mako Boats 1901 Inshore 2007 could be the deciding factor.
Bottom line: Choose the Mako Boats 1901 Inshore 2007 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Mako Boats 191 Inshore 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
