It's true we didn't show them side by side, but the only difference is in the dimensions, and it's subtle enough that it's hard to tell without actually sitting inside them yourself.
The 12.10 will do well in most conditions you'd experience on Lake Ontario or Erie. When the conditions turn the worst though these are limited a bit by their length and the fact that there's no skeg or rudder option. If you expect to paddle rough conditions often then consider one of the longer Delta models, otherwise it's a great boat for these areas.
