Both the Stanley Boats Camp Tiller 18 ft. 2010 and the Stanley Boats Predator 20 ft. 2012 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?
On paper these two are close siblings in the size department - Stanley Boats Camp Tiller 18 ft. 2010 at 18,0 ft versus Stanley Boats Predator 20 ft. 2012 at 20,0 ft. Weight tells a clearer story for trailering families: the Stanley Boats Predator 20 ft. 2012 tips the scales at 1 400 lbs - 700 lbs less than the Stanley Boats Camp Tiller 18 ft. 2010 at 700 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 Stanley Boats Predator 20 ft. 2012 has a 30-hp advantage over the Stanley Boats Camp Tiller 18 ft. 2010's 60-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 5 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: Performance buyers should lean toward the Stanley Boats Predator 20 ft. 2012 and its 90-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Stanley Boats Camp Tiller 18 ft. 2010 with its 60-hp rating is the more economical daily driver.
