While we've never been "off shore", this past weekend in Lake Michigan we did travel in confused seas with 4+ waves. It was a slow go, continuously working on course corrections (AKA driving the boat) and we did get bumped around yet never felt like we were in any danger. Exciting but not sure if I'd want to do it for any extended time. We were following a trawler which did run in a straight line but did have significantly more roll due to the full displacement hull design.
Would I take it out in heavier seas? Nope. A man has to know his limits.
