Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis - 20 ft. 2008 vs ThunderJet Havasu 2008: A Close Look at Two Modified-V Boats
Both the ThunderJet Alexis - 20 ft. 2008 and the ThunderJet Havasu 2008 are modified-V designs, both built in aluminium, so 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?
Both boats share a closely matched power ceiling - 425 hp for the ThunderJet Alexis - 20 ft. 2008 and 425 hp for the ThunderJet Havasu 2008. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 50 gal and 50 gal - so range won't be a tiebreaker here.
Both boats are rated for 8 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 - 20 ft. 2008 and ThunderJet Havasu 2008 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.
