Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis - 20 ft. 2008 vs ThunderJet Alexis 2009 — A Close Look at Two Modified Vees
When two boats share the same hull type — in this case both the ThunderJet Alexis - 20 ft. 2008 and the ThunderJet Alexis 2009 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 power gap is worth calling out. Rated to 425 hp, the ThunderJet Alexis - 20 ft. 2008 has a 100-hp advantage over the ThunderJet Alexis 2009's 325-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 5 gal and 5 gal — so range won't be a tiebreaker here.
The ThunderJet Alexis - 20 ft. 2008 is rated for up to 8 people. Passenger data for the ThunderJet Alexis 2009 wasn't available.
Bottom line: Performance buyers should lean toward the ThunderJet Alexis - 20 ft. 2008 and its 425-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the ThunderJet Alexis 2009 with its 325-hp rating is the more economical daily driver.
