Re: Irwin 52' video. You gotta' see this...
I love the outfit on the boat. And after 10 years on an Irwin 54' I just don't get the basing of the line. Yes there were a few boats that had issues, but that could be said for almost every builder.
The one thing I noticed was it looks to me like the dinette on the port side was actually a refit addition. I may be wrong, but on our 54, and a friends 52, where your dinette is was originally a stateroom. For us it was a necessity because we had five people living aboard. We also stripped out the bunk beds and switched it to a single berth that was larger than the bunk beds.
All in all I loved the Irwin, and despite many boats since then, it has always has a special place in my heart. No the least because of the way it sailed (at least with a good trade wind).
