The ShearWater 20TE 2012 vs ShearWater 2200Z 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - ShearWater 20TE 2012 at 20,0 ft versus ShearWater 2200Z 2005 at 21,0 ft. At 1 600 lbs and 1 650 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 250 hp, the ShearWater 2200Z 2005 has a 100-hp advantage over the ShearWater 20TE 2012's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the ShearWater 2200Z 2005 carries 80 gallons versus 56 gallons in the ShearWater 20TE 2012. 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: Performance buyers should lean toward the ShearWater 2200Z 2005 and its 250-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the ShearWater 20TE 2012 with its 150-hp rating is the more economical daily driver.
