The PlayCraft Ultra Deck Cruiser 20 OB 2006 vs PlayCraft Ultra Deck Cruiser 22 I/O 2005 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 Ultra Deck Cruiser 20 OB 2006 at 20,0 ft versus PlayCraft Ultra Deck Cruiser 22 I/O 2005 at 22,0 ft. Weight tells a clearer story for trailering families: the PlayCraft Ultra Deck Cruiser 22 I/O 2005 tips the scales at 3 550 lbs - 1 350 lbs less than the PlayCraft Ultra Deck Cruiser 20 OB 2006 at 2 200 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 200 hp, the PlayCraft Ultra Deck Cruiser 20 OB 2006 has a 194-hp advantage over the PlayCraft Ultra Deck Cruiser 22 I/O 2005's 6-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 41 gal and 41 gal - so range won't be a tiebreaker here.
Both boats are rated for 8 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 OB 2006 and its 200-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the PlayCraft Ultra Deck Cruiser 22 I/O 2005 with its 6-hp rating is the more economical daily driver.
