When two boats share the same hull type — in this case both the Weeres Cadet Fish 180 - 7 2013 and the Weeres SunDeck 220 Tri-toon 2007 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 Weeres SunDeck 220 Tri-toon 2007 measures 22,0 feet overall (2007), giving it roughly 3,8 additional feet of deck space compared to the Weeres Cadet Fish 180 - 7 2013 at 18,3 feet (2013). Weight tells a clearer story for trailering families: the Weeres SunDeck 220 Tri-toon 2007 tips the scales at 2 115 lbs — 2 009 lbs less than the Weeres Cadet Fish 180 - 7 2013 at 106 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 Weeres SunDeck 220 Tri-toon 2007 has a 115-hp advantage over the Weeres Cadet Fish 180 - 7 2013's 60-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 Weeres Cadet Fish 180 - 7 2013 is rated for 8 passengers, while the Weeres SunDeck 220 Tri-toon 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Weeres Cadet Fish 180 - 7 2013 could be the deciding factor.
Bottom line: Choose the Weeres Cadet Fish 180 - 7 2013 if your priority is putting more people on the water — it handles 8 passengers and at 18,3 ft it has the deck room to back that rating up comfortably. The Weeres SunDeck 220 Tri-toon 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.
