You're probably thinking, what does a cruise ship extension mean exactly? Well, just that actually because Silversea's Silver Spirit is being sliced in half so a completely new pre-built midsection can be added in. This project is expected to last until May as 500 skilled workers put 450,000 estimated hours into finishing this 49-feet-long addition. The upgraded ship's first expedition will be a seven-day cruise from Rome to Barcelona. So, anyone down for a cruise?
