Yep. Still have it. Been out in the open ocean off WA and OR with it, so it certainly can handle the Great Lakes. Its quite stable, to the point that I have hauled up heavy crab pots and hard fighting fish >10# without any problms.
As far as effeciency goes, you generally trade that off for stability.That said it is still not bad for effeciency. Ask away if you have other questions.
