Both the Crest Caribbean 20 2008 and the Crest Crest II 230 2013 are pontoon designs, both built in aluminium, so 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 Crest Crest II 230 2013 measures 23,5 feet overall (2013), giving it roughly 3,5 additional feet of deck space compared to the Crest Caribbean 20 2008 at 20,0 feet (2008). At 2 520 lbs and 2 455 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 140 hp, the Crest Crest II 230 2013 has a 25-hp advantage over the Crest Caribbean 20 2008's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 13 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 Crest Crest II 230 2013 at 23,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Crest Caribbean 20 2008 at 20,0 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.
