Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis OB Offshore 2009 vs ThunderJet Rio Classic 2013 — A Close Look at Two Modified Vees
When two boats share the same hull type — in this case both the ThunderJet Alexis OB Offshore 2009 and the ThunderJet Rio Classic 2013 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?
On paper these two are close siblings in the size department — ThunderJet Alexis OB Offshore 2009 at 21,0 ft versus ThunderJet Rio Classic 2013 at 22,0 ft. At 24 lbs and 42 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The ThunderJet Rio Classic 2013 tops out at 320 hp. Engine specs for the ThunderJet Alexis OB Offshore 2009 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 5 gal and 8 gal — so range won't be a tiebreaker here.
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.
Bottom line: The ThunderJet Alexis OB Offshore 2009 and ThunderJet Rio Classic 2013 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
