Both the Larson 1750 LX 2010 and the Larson SEi 180 Ski Fish O/B 2006 are modified-V designs, so 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 1750 LX 2010 at 17,1 ft versus Larson SEi 180 Ski Fish O/B 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Larson 1750 LX 2010 tips the scales at 2 040 lbs - 340 lbs more than the Larson SEi 180 Ski Fish O/B 2006 at 1 700 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

Both boats share a closely matched power ceiling - 150 hp for the Larson 1750 LX 2010 and 150 hp for the Larson SEi 180 Ski Fish O/B 2006. 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.

For family outings this is probably the sharpest distinction between the two. The Larson 1750 LX 2010 is rated for 7 passengers, while the Larson SEi 180 Ski Fish O/B 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Larson 1750 LX 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Larson SEi 180 Ski Fish O/B 2006 comes in at 11 lbs per hp versus 14 lbs per hp for the Larson 1750 LX 2010. 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.
