ThunderJet Alexis Outboard - 21 ft. 2008 vs ThunderJet Maxim Classic 2009 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the ThunderJet Alexis Outboard - 21 ft. 2008 and the ThunderJet Maxim Classic 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?

For family outings this is probably the sharpest distinction between the two. The ThunderJet Maxim Classic 2009 is rated for 7 passengers, while the ThunderJet Alexis Outboard - 21 ft. 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Maxim Classic 2009 could be the deciding factor.

Bottom line: Choose the ThunderJet Maxim Classic 2009 if your priority is putting more people on the water — it handles 7 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Alexis Outboard - 21 ft. 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
