When two boats share the same hull type — in this case both the Fiesta Marine 15 ft. Sunray Mini Sunfisher 2012 and the Fiesta Marine 20 ft. Carrera Sport Fundeck "L" 2012 are pontoon designs with aluminum 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?
Bottom line: The Fiesta Marine 15 ft. Sunray Mini Sunfisher 2012 at 15,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Fiesta Marine 20 ft. Carrera Sport Fundeck "L" 2012 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.
