Posidonia used to be in Cala Blava, Porto Petro, & Pollensa & yes, you booked on line, or if you went there the guy in the dingy might put you on a buoy if they had openings. Those were the days when they were free. Now they no longer show up on Posidonia's web site so I can only assume they no longer operate those buoys.
We haven't gotten up the East coast
for a couple of years. Are the buoys still in Porto Petro? And do they look to be maintained? That's something I'd like to know. If so, I might GUESS they've been abandoned & are no longer maintained by the same people, or perhaps have been taken over by some local group. If not, I'd greatly fear another bottom has been fouled when the mooring
field was abandoned but the bottom never cleaned up properly.
This is a real problem in Spain
. The government
(that would be the taxpayers) pay for & build the infrastructure, then grant the concession to operate it to a private entity (usually a buddy of the official in charge), who rakes in big profits as he hasn't had to invest in the infrastructure. The same is true with Cabrera, which used to be run by the military & was free.
Also, due in large part to the high cost of moorings in the Balearics, local boat
owners set their own mooring balls in nice anchorages
, then abandon them later, leaving the bottom a scary place for those who wish to anchor
. This is one of our biggest concerns now in the Balearics--fouled bottoms. Some areas, such as Es Trench, are easy as you can see the sandy bottom. Others, such as Porto Colom, are scary indeed if you have seen the number of buoys that have been put in over the years, and then the next year you come back & find no buoys but you know (& sometimes find) the weights still on the bottom.
