Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis OB Offshore - 22 ft. 2008 vs ThunderJet Bull Dog 20 ft. 2013 — Which Modified Vee Fits Your Needs?
When two boats share the same hull type — in this case both the ThunderJet Alexis OB Offshore - 22 ft. 2008 and the ThunderJet Bull Dog 20 ft. 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?
The power gap is worth calling out. Rated to 500 hp, the ThunderJet Alexis OB Offshore - 22 ft. 2008 has a 180-hp advantage over the ThunderJet Bull Dog 20 ft. 2013's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the ThunderJet Bull Dog 20 ft. 2013 carries 48 gallons versus 5 gallons in the ThunderJet Alexis OB Offshore - 22 ft. 2008. 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 Offshore - 22 ft. 2008 at 22,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The ThunderJet Bull Dog 20 ft. 2013 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
