Can you sink Tall Ships?

Solution 1:

I believe that any ship can be sunk, but there are multiple ships with cannons and sails. I've sunken the first two, but it doesn't take a certain number of hits, I don't think. I think you just have to rock it until everybody falls off, then it breaks on it's own. I don't know if you have to be a certain size, but you can sink the first cannon one easily at 100 tons, and I think you have to be close to there for them to come.(Just had the second one come when I was really small, but it killed me before I could attack it.) Remember to use your boosts to jump up and fall on them.

EDIT: These are the two I'm talking about. That's as far as I've gotten so far, as that was one of Moby's last moments. :(
