When two boats share the same hull type — in this case both the Larson SEi 180 Ski Fish 2009 and the Larson SEi 180 Ski Fish I/O 2006 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 — Larson SEi 180 Ski Fish 2009 at 17,0 ft versus Larson SEi 180 Ski Fish I/O 2006 at 17,0 ft. At 265 lbs and 265 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 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.
