I've been in touch with the guys at Almerimar. They are well overbooked.
For end of September, they do not have any available moorings from 40 to 49 footers. They have larger moorings, for 54 footers. Below 40 feet (40 feet included I believe), they might have some availability.
If your boat is in that size (40 to 49), you will probably get a 54 feet mooring
(and get charged for it too).
What is your vessel's LOA
?, can you brief me in your plans, so I can suggest alternatives?.
