When two boats share the same hull type — in this case both the Larson FX 1750 SC O/B 2012 and the Larson SEi 180 Ski Fish O/B 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 — Larson FX 1750 SC O/B 2012 at 17,4 ft versus Larson SEi 180 Ski Fish O/B 2007 at 17,0 ft. At 16 lbs and 17 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 — 150 hp for the Larson FX 1750 SC O/B 2012 and 150 hp for the Larson SEi 180 Ski Fish O/B 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 — 23 gal and 23 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 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 Larson SEi 180 Ski Fish O/B 2007 comes in at 0 lbs per hp versus 0 lbs per hp for the Larson FX 1750 SC O/B 2012. 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.
