When two boats share the same hull type — in this case both the ThunderJet Alexis 2010 and the ThunderJet Havasu 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 power gap is worth calling out. Rated to 325 hp, the ThunderJet Alexis 2010 has a 300-hp advantage over the ThunderJet Havasu 2010's 25-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.
