Both the Stanley Boats 20 Predator 2011 and the Stanley Boats Tiller 16 ft. DC 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?
Size is the most obvious dividing line here. The Stanley Boats 20 Predator 2011 measures 20,0 feet overall (2011), giving it roughly 4,0 additional feet of deck space compared to the Stanley Boats Tiller 16 ft. DC 2012 at 16,0 feet (2012). Weight tells a clearer story for trailering families: the Stanley Boats 20 Predator 2011 tips the scales at 1 400 lbs - 875 lbs more than the Stanley Boats Tiller 16 ft. DC 2012 at 525 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 20 Predator 2011 has a 50-hp advantage over the Stanley Boats Tiller 16 ft. DC 2012's 40-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 4 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: The Stanley Boats 20 Predator 2011 at 20,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Stanley Boats Tiller 16 ft. DC 2012 at 16,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
