The PlayCraft FX4 FishDeck 20 2011 vs PlayCraft Ultra Deck Cruiser 20 I/O 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - PlayCraft FX4 FishDeck 20 2011 at 20,0 ft versus PlayCraft Ultra Deck Cruiser 20 I/O 2006 at 20,0 ft. Weight tells a clearer story for trailering families: the PlayCraft Ultra Deck Cruiser 20 I/O 2006 tips the scales at 3 300 lbs - 1 300 lbs less than the PlayCraft FX4 FishDeck 20 2011 at 2 000 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 260 hp, the PlayCraft Ultra Deck Cruiser 20 I/O 2006 has a 60-hp advantage over the PlayCraft FX4 FishDeck 20 2011's 200-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the PlayCraft FX4 FishDeck 20 2011 carries 70 gallons versus 41 gallons in the PlayCraft Ultra Deck Cruiser 20 I/O 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 10 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 PlayCraft Ultra Deck Cruiser 20 I/O 2006 and its 260-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the PlayCraft FX4 FishDeck 20 2011 with its 200-hp rating is the more economical daily driver.
