When two boats share the same hull type — in this case both the Crestliner TC 18 2011 and the Crestliner XCR 1667V 2010 are modified vee 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?
On paper these two are close siblings in the size department — Crestliner TC 18 2011 at 18,3 ft versus Crestliner XCR 1667V 2010 at 16,0 ft. Weight tells a clearer story for trailering families: the Crestliner TC 18 2011 tips the scales at 1 044 lbs — 769 lbs more than the Crestliner XCR 1667V 2010 at 275 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 75 hp, the Crestliner TC 18 2011 has a 55-hp advantage over the Crestliner XCR 1667V 2010's 20-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 XCR 1667V 2010 is rated for 5 passengers, while the Crestliner TC 18 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner XCR 1667V 2010 could be the deciding factor.
Bottom line: Choose the Crestliner XCR 1667V 2010 if your priority is putting more people on the water — it handles 5 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Crestliner TC 18 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
