Several crew members and swimmers issued an alarm on Tuesday about "saturation" in Portals Vells.
This is an example of what can happen in other parts of the Majorcan coastline.
"The bay is packed with boats and, to top it all off, party boats with more than 300 people, creating conflict situations with other boats and saturating the beaches," says a witness.
The images show that a catamaran filled with tourists is manoeuvring to leave the area, passing dangerously close to other anchored boats, as well as swimmers in this area of Calvia.
