When two boats share the same hull type — in this case both the Vectra 2402 I/O 2010 and the Vectra V-172 IO Fish-n-Ski 2009 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?

Size is the most obvious dividing line here. The Vectra 2402 I/O 2010 measures 21,6 feet overall (2010), giving it roughly 5,6 additional feet of deck space compared to the Vectra V-172 IO Fish-n-Ski 2009 at 16,0 feet (2009). Weight tells a clearer story for trailering families: the Vectra 2402 I/O 2010 tips the scales at 2 945 lbs — 2 790 lbs more than the Vectra V-172 IO Fish-n-Ski 2009 at 155 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.

The power gap is worth calling out. Rated to 425 hp, the Vectra 2402 I/O 2010 has a 205-hp advantage over the Vectra V-172 IO Fish-n-Ski 2009's 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Vectra 2402 I/O 2010 carries 51 gallons versus 23 gallons in the Vectra V-172 IO Fish-n-Ski 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Vectra 2402 I/O 2010 is rated for 13 passengers, while the Vectra V-172 IO Fish-n-Ski 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Vectra 2402 I/O 2010 could be the deciding factor.
