When two boats share the same hull type — in this case both the Avalon 20 ft. C Fish - Rear Fish RE 2012 and the Avalon Deco Funship 2013 are pontoon 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?

Size is the most obvious dividing line here. The Avalon Deco Funship 2013 measures 27,0 feet overall (2013), giving it roughly 25,0 additional feet of deck space compared to the Avalon 20 ft. C Fish - Rear Fish RE 2012 at 2,0 feet (2012). Weight tells a clearer story for trailering families: the Avalon Deco Funship 2013 tips the scales at 4 485 lbs — 4 467 lbs less than the Avalon 20 ft. C Fish - Rear Fish RE 2012 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 250 hp, the Avalon Deco Funship 2013 has a 135-hp advantage over the Avalon 20 ft. C Fish - Rear Fish RE 2012's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Avalon Deco Funship 2013 is rated for 17 passengers, while the Avalon 20 ft. C Fish - Rear Fish RE 2012 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Deco Funship 2013 could be the deciding factor.

Both are 2-tube and 3-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
