Few big Lakes "scare" me. The two that do are
Superior
Huron
followed by Simcoe in the fall.

Type of guy I am, if I lived in OS I might have a boat suitable for those waters. I know I wouldn't own a boat I'd feel comfortable taking into Huron asi ti would be large, expensive and not something Id want to tow around to fish somewhere other than Huron out of SH, Kincardine etc.

So a boat for OS would be small, versatile, something I could make use of in many places. A boat that id use for Huron would be parked somewhere there permantly and not too often used, other than trolling offshore there.
