ThunderJet Alexis 2011 vs ThunderJet Alexis OB OS 2011 — Same Brand, Different Boat

Matching a modified vee ThunderJet Alexis 2011 against a deep vee ThunderJet Alexis OB OS 2011 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.

The power gap is worth calling out. Rated to 425 hp, the ThunderJet Alexis 2011 has a 125-hp advantage over the ThunderJet Alexis OB OS 2011's 300-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.

Bottom line: Performance buyers should lean toward the ThunderJet Alexis 2011 and its 425-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the ThunderJet Alexis OB OS 2011 with its 300-hp rating is the more economical daily driver.

How many people can each boat hold?

The ThunderJet Alexis OB OS 2011 measures 102" wide, compared to 96" for the ThunderJet Alexis 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the ThunderJet Alexis 2011 and ThunderJet Alexis OB OS 2011?
Both boats carry similar fuel loads — 48 gallons and 48 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the ThunderJet Alexis 2011 and ThunderJet Alexis OB OS 2011 from the same manufacturer?
Yes — both the ThunderJet Alexis 2011 and the ThunderJet Alexis OB OS 2011 are built by ThunderJet.
