Ice in the St Lawrence River at Montreal

[drozeboom]

Could you be more specific about what the "underwater mechanical damage" is? There is probably enought experience on this board to have an idea what happened. What is the name of the vessel?

I have been sailing 30 years on the St.Lawrence and have never seen ice much before December? Do you have any shots of the damage?

no ice during that time of year, espicially with the mild winter last year.

I live in Singapore and would greatly appreciate input from your local knowledge as I am getting nowhere searching elsewhere on the Internet.
I am trying to understand how mechanical damage (that looks like ice damage) could have occurred to the underwater of a ship that has traded generally in temperate/tropical waters. The Only time that I can see that she could possibly have encountered ice was on visits to Montreal in September/October 2009.
Is it possible for ice still to have been floating in the water at that time of year?
All comments would be most welcome.
