When two boats share the same hull type — in this case both the ThunderJet Alexis 2011 and the ThunderJet Alexis Classic 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 425 hp, the ThunderJet Alexis 2011 has a 100-hp advantage over the ThunderJet Alexis Classic 2010's 325-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the ThunderJet Alexis 2011 carries 48 gallons versus 8 gallons in the ThunderJet Alexis Classic 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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.
