Both the ThunderJet Alexis OB 2010 and the ThunderJet Denali 2009 are modified-V designs, both built in aluminium, 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 - ThunderJet Alexis OB 2010 at 20,0 ft versus ThunderJet Denali 2009 at 20,0 ft. Weight tells a clearer story for trailering families: the ThunderJet Denali 2009 tips the scales at 2 500 lbs - 700 lbs less than the ThunderJet Alexis OB 2010 at 1 800 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 ThunderJet Denali 2009 tops out at 200 hp. Engine specs for the ThunderJet Alexis OB 2010 aren't listed - confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads - 50 gal and 50 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.
Bottom line: The ThunderJet Alexis OB 2010 and ThunderJet Denali 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
