When two boats share the same hull type — in this case both the Kenner 21 VX Tunnel 2008 and the Kenner 24 VX 2008 are deep 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 — Kenner 21 VX Tunnel 2008 at 21,0 ft versus Kenner 24 VX 2008 at 24,0 ft. Weight tells a clearer story for trailering families: the Kenner 21 VX Tunnel 2008 tips the scales at 1 375 lbs — 1 140 lbs more than the Kenner 24 VX 2008 at 235 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 275 hp, the Kenner 24 VX 2008 has a 50-hp advantage over the Kenner 21 VX Tunnel 2008's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Kenner 24 VX 2008 carries 96 gallons versus 6 gallons in the Kenner 21 VX Tunnel 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 8 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.
Bottom line: The Kenner 24 VX 2008 at 24,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Kenner 21 VX Tunnel 2008 at 21,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
