Detailed Evaluation & Buyer Recommendation
Crestliner CR 1648 2004 vs Crestliner Grand Cayman 2185 2010 — Same Brand, Different Boat
The Crestliner CR 1648 2004 vs Crestliner Grand Cayman 2185 2010 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
The power gap is worth calling out. Rated to 115 hp, the Crestliner Grand Cayman 2185 2010 has a 80-hp advantage over the Crestliner CR 1648 2004's 35-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Crestliner Grand Cayman 2185 2010 is rated for 12 passengers, while the Crestliner CR 1648 2004 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Grand Cayman 2185 2010 could be the deciding factor.
Bottom line: Choose the Crestliner Grand Cayman 2185 2010 if your priority is putting more people on the water — it handles 12 passengers and at 20,5 ft it has the deck room to back that rating up comfortably. The Crestliner CR 1648 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
