When two boats share the same hull type — in this case both the Avalon 24 ft. Windjammer 2013 and the Avalon Bow Fish 18 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 24 ft. Windjammer 2013 measures 24,0 feet overall (2013), giving it roughly 6,0 additional feet of deck space compared to the Avalon Bow Fish 18 ft. 2010 at 18,0 feet (2010). Weight tells a clearer story for trailering families: the Avalon 24 ft. Windjammer 2013 tips the scales at 225 lbs — 209 lbs more than the Avalon Bow Fish 18 ft. 2010 at 16 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 135 hp, the Avalon 24 ft. Windjammer 2013 has a 60-hp advantage over the Avalon Bow Fish 18 ft. 2010's 75-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 24 ft. Windjammer 2013 is rated for 13 passengers, while the Avalon Bow Fish 18 ft. 2010 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avalon 24 ft. Windjammer 2013 could be the deciding factor.

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