ThunderJet Alexis Classic 2013 vs ThunderJet Bull Dog 18 ft. 2011 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the ThunderJet Alexis Classic 2013 and the ThunderJet Bull Dog 18 ft. 2011 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 2013 carries a rated maximum of 320 hp. Engine data for the ThunderJet Bull Dog 18 ft. 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The ThunderJet Alexis Classic 2013 is rated for 6 passengers, while the ThunderJet Bull Dog 18 ft. 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Alexis Classic 2013 could be the deciding factor.

Bottom line: Choose the ThunderJet Alexis Classic 2013 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Bull Dog 18 ft. 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
