What happened to the Rialto? No mention of her.. I did a Great Lakes trip on her around 1962 for grain, aged about 15, first trip as a sailors peggy..
As I remember it,
Hull - Aberdeen - Quebec - Montreal, -Toronto, - Hamilton - Aberden - Hull
I paid off with about a tenner and an AB on the beach 'helped' me spend it before I even got on the train home..
