Both the Crestliner Pro Tiller 1850 2011 and the Crestliner Sportsmen Series 14 SS SC 2009 are modified-V 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 Crestliner Pro Tiller 1850 2011 measures 18,7 feet overall (2011), giving it roughly 4,7 additional feet of deck space compared to the Crestliner Sportsmen Series 14 SS SC 2009 at 14,0 feet (2009). Weight tells a clearer story for trailering families: the Crestliner Pro Tiller 1850 2011 tips the scales at 1 400 lbs - 880 lbs more than the Crestliner Sportsmen Series 14 SS SC 2009 at 520 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 90 hp, the Crestliner Pro Tiller 1850 2011 has a 55-hp advantage over the Crestliner Sportsmen Series 14 SS SC 2009'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 Pro Tiller 1850 2011 is rated for 6 passengers, while the Crestliner Sportsmen Series 14 SS SC 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Pro Tiller 1850 2011 could be the deciding factor.
Bottom line: Choose the Crestliner Pro Tiller 1850 2011 if your priority is putting more people on the water - it handles 6 passengers and at 18,7 ft it has the deck room to back that rating up comfortably. The Crestliner Sportsmen Series 14 SS SC 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
