Matching a deep vee ThunderJet 185 Explorer 2012 against a modified vee ThunderJet Havasu 2009 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The ThunderJet 185 Explorer 2012 measures 20,4 feet overall (2012), giving it roughly 18,4 additional feet of deck space compared to the ThunderJet Havasu 2009 at 2,0 feet (2009). At 13 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 150 hp, the ThunderJet 185 Explorer 2012 has a 125-hp advantage over the ThunderJet Havasu 2009'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 185 Explorer 2012 carries 48 gallons versus 5 gallons in the ThunderJet Havasu 2009. 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 185 Explorer 2012 at 20,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The ThunderJet Havasu 2009 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.
