When two boats share the same hull type — in this case both the Spectre 368sc 2010 and the Spectre SCX43 2011 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?
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 SCX43 2011 at 42,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Spectre 368sc 2010 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.
