When two boats share the same hull type — in this case both the ThunderJet Bull Dog 20 ft. 2013 and the ThunderJet Havasu 2010 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 Bull Dog 20 ft. 2013 at 2,0 ft versus ThunderJet Havasu 2010 at 2,0 ft. At 33 lbs and 26 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 power gap is worth calling out. Rated to 320 hp, the ThunderJet Bull Dog 20 ft. 2013 has a 295-hp advantage over the ThunderJet Havasu 2010's 25-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 Havasu 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.
At this size, power-to-weight ratio matters more than outright horsepower. The ThunderJet Bull Dog 20 ft. 2013 comes in at 0 lbs per hp versus 1 lbs per hp for the ThunderJet Havasu 2010. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Performance buyers should lean toward the ThunderJet Bull Dog 20 ft. 2013 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the ThunderJet Havasu 2010 with its 25-hp rating is the more economical daily driver.
