The ThunderJet 185 Explorer 2012 is a deep-V design and the ThunderJet Bull Dog 20 ft. 2012 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - ThunderJet 185 Explorer 2012 at 20,4 ft versus ThunderJet Bull Dog 20 ft. 2012 at 20,0 ft. Weight tells a clearer story for trailering families: the ThunderJet Bull Dog 20 ft. 2012 tips the scales at 3 300 lbs - 2 000 lbs less than the ThunderJet 185 Explorer 2012 at 1 300 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 320 hp, the ThunderJet Bull Dog 20 ft. 2012 has a 170-hp advantage over the ThunderJet 185 Explorer 2012's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 48 gal and 48 gal - so range won't be a tiebreaker here.

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.
