yuk..I sailed safely through the Tyrrhenian Sea many times
but I must admit that it isn't the safest way to travel
besides the fact that you must spend hours on a ferry with nothing to do but bars and slot machines you're always in the middle of nowhere with nothing to watch but the waves
I do prefer traveling by air...but sometimes you just have no choices

This is from one of my past years trip on the ferry boat to Sardinia (aka The Hell or The Journey of Hope)
