When two boats share the same hull type — in this case both the Avalon 14 ft. Eagle - Fish 2011 and the Avalon Windjammer 20 ft. 2010 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 14 ft. Eagle - Fish 2011 measures 14,0 feet overall (2011), giving it roughly 12,0 additional feet of deck space compared to the Avalon Windjammer 20 ft. 2010 at 2,0 feet (2010). At 115 lbs and 175 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 90 hp, the Avalon Windjammer 20 ft. 2010 has a 50-hp advantage over the Avalon 14 ft. Eagle - Fish 2011's 40-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 Windjammer 20 ft. 2010 is rated for 9 passengers, while the Avalon 14 ft. Eagle - Fish 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon Windjammer 20 ft. 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Avalon Windjammer 20 ft. 2010 comes in at 2 lbs per hp versus 3 lbs per hp for the Avalon 14 ft. Eagle - Fish 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 23" diameter. That shared spec means stability and buoyancy characteristics are closely matched — the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
Bottom line: Choose the Avalon Windjammer 20 ft. 2010 if your priority is putting more people on the water — it handles 9 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Avalon 14 ft. Eagle - Fish 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
