When two boats share the same hull type — in this case both the ThunderJet Bull Dog 20 ft. 2013 and the ThunderJet Landing Craft 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?

The power gap is worth calling out. Rated to 320 hp, the ThunderJet Bull Dog 20 ft. 2013 has a 170-hp advantage over the ThunderJet Landing Craft 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.
