When two boats share the same hull type — in this case both the Rinker Captiva 226 BR 2012 and the Rinker Express Cruiser 340 EC 2012 are deep 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?
Both boats share a closely matched power ceiling — 300 hp for the Rinker Captiva 226 BR 2012 and 320 hp for the Rinker Express Cruiser 340 EC 2012. 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 Rinker Express Cruiser 340 EC 2012 carries 168 gallons versus 42 gallons in the Rinker Captiva 226 BR 2012. 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 Rinker Express Cruiser 340 EC 2012 is rated for 10 passengers, while the Rinker Captiva 226 BR 2012 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Rinker Express Cruiser 340 EC 2012 could be the deciding factor.
Bottom line: Choose the Rinker Express Cruiser 340 EC 2012 if your priority is putting more people on the water — it handles 10 passengers and at 35,7 ft it has the deck room to back that rating up comfortably. The Rinker Captiva 226 BR 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
