When two boats share the same hull type — in this case both the Stanley Boats 18 Predator 2011 and the Stanley Boats Camp Tiller 20 ft. 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 — Stanley Boats 18 Predator 2011 at 18,0 ft versus Stanley Boats Camp Tiller 20 ft. 2010 at 19,2 ft. Weight tells a clearer story for trailering families: the Stanley Boats Camp Tiller 20 ft. 2010 tips the scales at 725 lbs — 713 lbs less than the Stanley Boats 18 Predator 2011 at 12 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.
Both boats share a closely matched power ceiling — 75 hp for the Stanley Boats 18 Predator 2011 and 60 hp for the Stanley Boats Camp Tiller 20 ft. 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The Stanley Boats Camp Tiller 20 ft. 2010 is rated for 5 passengers, while the Stanley Boats 18 Predator 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stanley Boats Camp Tiller 20 ft. 2010 could be the deciding factor.
Bottom line: Choose the Stanley Boats Camp Tiller 20 ft. 2010 if your priority is putting more people on the water — it handles 5 passengers and at 19,2 ft it has the deck room to back that rating up comfortably. The Stanley Boats 18 Predator 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.
