When two boats share the same hull type — in this case both the Spectre 428sc 2010 and the Spectre SC36 2012 are catamaran 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?
The Spectre SC36 2012 tops out at 430 hp. Engine specs for the Spectre 428sc 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Spectre 428sc 2010 carries 274 gallons versus 174 gallons in the Spectre SC36 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: The Spectre 428sc 2010 at 42,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Spectre SC36 2012 at 35,8 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.
