When two boats share the same hull type — in this case both the ShearWater 20TE 2013 and the ShearWater 23LTZ 2010 are modified vee designs with fiberglass 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?
Size is the most obvious dividing line here. The ShearWater 23LTZ 2010 measures 22,0 feet overall (2010), giving it roughly 20,0 additional feet of deck space compared to the ShearWater 20TE 2013 at 2,0 feet (2013). At 16 lbs and 19 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 300 hp, the ShearWater 23LTZ 2010 has a 150-hp advantage over the ShearWater 20TE 2013'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 23LTZ 2010 carries 81 gallons versus 56 gallons in the ShearWater 20TE 2013. 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: The ShearWater 23LTZ 2010 at 22,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The ShearWater 20TE 2013 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
