On final for the ILS 11; we noticed a cruise ship departing the dock to the left of final; heading towards the southeast. There is a note on the airport page for Aruba which states that 'ships transit the Runway 11 approach path. Tower coordination is required prior to a ship being permitted to transit'. Tower did not inform us of that the ship had permission to cross our path on final. Approximately 1000 feet on final I made the decision to go-around as a possible collision of our aircraft/gear with the ships 'whale tail' funnel was possible. As we executed the go-around; Tower did not understand the problem with the ship crossing final. When we fly our second approach; we estimated from the ships wake and position we may have cleared the ship by 100 feet.Tower was not concerned about the cruise ships paths crossing our final approach. I believe all approach need to be halted or reduced when a ship cross the final course. If there had been a cloud deck present; we would not have seen the ship until it was too late. This is an unnecessary risk for our flights.If the weather is less than 3000 and 5 miles; then Aruba needs to protect the final approach corridor and prevent any ships from crossing the final course to Runway 11.
Air Carrier Captain reported executing a go-around when the Captain believed there may be a possible air/ground conflict with a cruise ship passing through the final approach area at TNCA airport.
