De Falco wasn't making any puns, the expression "un'anima di guai" literally translates to "a soul of troubles", and has nothing to do with boats.
In fact, De Falco could have used the much more common expression "un mare di guai", which translates to "a sea of troubles".
And Shittino, a clown who killed 30 people because it wanted to show off in front of his mentally challenged 5 out of 10 whore, is still out of jail because reasons.
