PlayCraft Sunfish FishDeck FX4-18 OB 2005 vs PlayCraft Ultra Deck Cruiser 22 I/O 2007 — Same Brand, Different Boat

The PlayCraft Sunfish FishDeck FX4-18 OB 2005 vs PlayCraft Ultra Deck Cruiser 22 I/O 2007 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.

Size is the most obvious dividing line here. The PlayCraft Ultra Deck Cruiser 22 I/O 2007 measures 22,0 feet overall (2007), giving it roughly 4,0 additional feet of deck space compared to the PlayCraft Sunfish FishDeck FX4-18 OB 2005 at 18,0 feet (2005). Weight tells a clearer story for trailering families: the PlayCraft Ultra Deck Cruiser 22 I/O 2007 tips the scales at 355 lbs — 337 lbs less than the PlayCraft Sunfish FishDeck FX4-18 OB 2005 at 18 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 320 hp, the PlayCraft Ultra Deck Cruiser 22 I/O 2007 has a 185-hp advantage over the PlayCraft Sunfish FishDeck FX4-18 OB 2005's 135-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 Sunfish FishDeck FX4-18 OB 2005 carries 24 gallons versus 7 gallons in the PlayCraft Ultra Deck Cruiser 22 I/O 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The PlayCraft Sunfish FishDeck FX4-18 OB 2005 is rated for 8 passengers, while the PlayCraft Ultra Deck Cruiser 22 I/O 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the PlayCraft Sunfish FishDeck FX4-18 OB 2005 could be the deciding factor.

Bottom line: Choose the PlayCraft Sunfish FishDeck FX4-18 OB 2005 if your priority is putting more people on the water — it handles 8 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The PlayCraft Ultra Deck Cruiser 22 I/O 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.

PlayCraft Sunfish FishDeck FX4-18 OB 2005 vs PlayCraft Ultra Deck Cruiser 22 I/O 2007 — Common Questions

Which is the larger boat — the PlayCraft Sunfish FishDeck FX4-18 OB 2005 or the PlayCraft Ultra Deck Cruiser 22 I/O 2007?
The PlayCraft Ultra Deck Cruiser 22 I/O 2007 is the longer of the two at 22,0 feet overall. The PlayCraft Sunfish FishDeck FX4-18 OB 2005 comes in at 18,0 feet, making it roughly 4,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the PlayCraft Sunfish FishDeck FX4-18 OB 2005 or the PlayCraft Ultra Deck Cruiser 22 I/O 2007?
For trailering, the PlayCraft Sunfish FishDeck FX4-18 OB 2005 has the edge at 18 lbs dry weight versus 355 lbs for the PlayCraft Ultra Deck Cruiser 22 I/O 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The PlayCraft Ultra Deck Cruiser 22 I/O 2007 is rated to a maximum of 320 hp, giving it the larger power ceiling. The PlayCraft Sunfish FishDeck FX4-18 OB 2005 tops out at 135 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The PlayCraft Sunfish FishDeck FX4-18 OB 2005 is Coast Guard rated for 8 passengers, while the PlayCraft Ultra Deck Cruiser 22 I/O 2007 is certified for 1. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the PlayCraft Sunfish FishDeck FX4-18 OB 2005 and PlayCraft Ultra Deck Cruiser 22 I/O 2007 share an 8 ft. 0 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the PlayCraft Sunfish FishDeck FX4-18 OB 2005 or the PlayCraft Ultra Deck Cruiser 22 I/O 2007?
The PlayCraft Sunfish FishDeck FX4-18 OB 2005 has the bigger tank at 24 gallons, versus 7 gallons on the PlayCraft Ultra Deck Cruiser 22 I/O 2007. That 17-gallon difference translates to roughly 51–85 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the PlayCraft Sunfish FishDeck FX4-18 OB 2005 and PlayCraft Ultra Deck Cruiser 22 I/O 2007 from the same manufacturer?
Yes — both the PlayCraft Sunfish FishDeck FX4-18 OB 2005 and the PlayCraft Ultra Deck Cruiser 22 I/O 2007 are built by PlayCraft. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
