When two boats share the same hull type — in this case both the ThunderJet Alexis Classic 2010 and the ThunderJet Alexis OB 2010 are modified vee designs with aluminum 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?
The ThunderJet Alexis Classic 2010 carries a rated maximum of 325 hp. Engine data for the ThunderJet Alexis OB 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 8 gal and 5 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 Classic 2010 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The ThunderJet Alexis OB 2010 at 2,0 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.
