When two boats share the same hull type — in this case both the Crestliner Jons - CR 1236 2009 and the Crestliner TC 18 2013 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?
Size is the most obvious dividing line here. The Crestliner TC 18 2013 measures 18,3 feet overall (2013), giving it roughly 7,3 additional feet of deck space compared to the Crestliner Jons - CR 1236 2009 at 11,0 feet (2009). Weight tells a clearer story for trailering families: the Crestliner TC 18 2013 tips the scales at 1 044 lbs — 1 030 lbs less than the Crestliner Jons - CR 1236 2009 at 14 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 2013 has a 65-hp advantage over the Crestliner Jons - CR 1236 2009's 10-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 TC 18 2013 is rated for 4 passengers, while the Crestliner Jons - CR 1236 2009 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner TC 18 2013 could be the deciding factor.
Bottom line: Choose the Crestliner TC 18 2013 if your priority is putting more people on the water — it handles 4 passengers and at 18,3 ft it has the deck room to back that rating up comfortably. The Crestliner Jons - CR 1236 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
