When two boats share the same hull type — in this case both the Bass Cat Bay Cat 2012 and the Bass Cat Eyra 2013 are modified vee designs with fiberglass 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?
On paper these two are close siblings in the size department — Bass Cat Bay Cat 2012 at 21,6 ft versus Bass Cat Eyra 2013 at 20,2 ft. Weight tells a clearer story for trailering families: the Bass Cat Eyra 2013 tips the scales at 1 725 lbs — 1 704 lbs less than the Bass Cat Bay Cat 2012 at 21 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.
Both boats share a closely matched power ceiling — 175 hp for the Bass Cat Bay Cat 2012 and 175 hp for the Bass Cat Eyra 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Bass Cat Bay Cat 2012 carries 72 gallons versus 52 gallons in the Bass Cat Eyra 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Bass Cat Bay Cat 2012 is rated for 7 passengers, while the Bass Cat Eyra 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bass Cat Bay Cat 2012 could be the deciding factor.
Bottom line: Choose the Bass Cat Bay Cat 2012 if your priority is putting more people on the water — it handles 7 passengers and at 21,6 ft it has the deck room to back that rating up comfortably. The Bass Cat Eyra 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
