ThunderJet Alexis OB 2010 vs ThunderJet Bull Dog 20 ft. 2012 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the ThunderJet Alexis OB 2010 and the ThunderJet Bull Dog 20 ft. 2012 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 2010 at 2,0 ft versus ThunderJet Bull Dog 20 ft. 2012 at 2,0 ft. At 18 lbs and 33 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 Bull Dog 20 ft. 2012 tops out at 320 hp. Engine specs for the ThunderJet Alexis OB 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the ThunderJet Bull Dog 20 ft. 2012 carries 48 gallons versus 5 gallons in the ThunderJet Alexis OB 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.

Bottom line: The ThunderJet Alexis OB 2010 and ThunderJet Bull Dog 20 ft. 2012 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.
