When two boats share the same hull type — in this case both the ThunderJet Alexis Classic 2011 and the ThunderJet Alexis Outboard - 20 ft. 2008 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 2011 carries a rated maximum of 425 hp. Engine data for the ThunderJet Alexis Outboard - 20 ft. 2008 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.
