When two boats share the same hull type — in this case both the Avalon 27 ft. Excalibur 2011 and the Avalon CC Fish - 20 Foot 2008 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 27 ft. Excalibur 2011 measures 27,0 feet overall (2011), giving it roughly 25,0 additional feet of deck space compared to the Avalon CC Fish - 20 Foot 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Avalon 27 ft. Excalibur 2011 tips the scales at 265 lbs — 107 lbs more than the Avalon CC Fish - 20 Foot 2008 at 158 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 175 hp, the Avalon 27 ft. Excalibur 2011 has a 85-hp advantage over the Avalon CC Fish - 20 Foot 2008's 90-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 27 ft. Excalibur 2011 is rated for 14 passengers, while the Avalon CC Fish - 20 Foot 2008 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon 27 ft. Excalibur 2011 could be the deciding factor.
Bottom line: Choose the Avalon 27 ft. Excalibur 2011 if your priority is putting more people on the water — it handles 14 passengers and at 27,0 ft it has the deck room to back that rating up comfortably. The Avalon CC Fish - 20 Foot 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
