Back in 1959/1960 my parents (I was only 4/5 years old) co-owned an Elco.  I always thought it was a 1929, 57', but now there's some confusion and my parents say it was something different.  But anyway, it has a sad ending.

The boat's name was Salani (I think that's the right spelling) and they took it up to The Thousand Island to do some diving off it.  They ended up having to bring across Lake Ontario late in the season and were rushing to get back in time before the locks closed for the year.  Lake Ontario was rough but they had to cross anyways.  They didn't get very far when the slight crack in the hull (left over from when she was a radio ship in the Mediterranean in WWII) opened up.  They lost her off of Galloo Island.  No one was hurt, the Coast Guard took the guys off the boat.  The following summer they dove on her and removed some stuff.  The only thing I remember for sure is the port hole which they put in a fireplace my parents had built years later.
