The ShearWater 2400Z 2005 vs ShearWater 25LTZ 2013 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 2400Z 2005 at 24,0 ft versus ShearWater 25LTZ 2013 at 24,5 ft. At 21 lbs and 24 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 350 hp, the ShearWater 25LTZ 2013 has a 50-hp advantage over the ShearWater 2400Z 2005'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 — 83 gal and 81 gal — so range won't be a tiebreaker here.
Both boats are rated for 7 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 25LTZ 2013 and its 350-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the ShearWater 2400Z 2005 with its 300-hp rating is the more economical daily driver.
