NAUTICAL GUIDE TO ANCHORING RESPECTING THE POSIDONIA IN MALLORCA
Anchoring in the crystal clear waters of Mallorca is a unique experience for any sailing enthusiast.
However, it is vital to do it responsibly to protect the Posidonia oceanica, a marine plant essential to the health of the marine ecosystems of the Balearic Islands.
Posidonia meadows are an endemic species of the Mediterranean Sea that is not present in any other sea in the world and that is why it is so vital to take care of it.
In this guide, we explain how to anchor respectfully in Mallorca, ensuring the preservation of this valuable natural resource.
WHAT IS POSIDONIA OCEANICA?
Neptune grass (Posidonia oceanica) is a marine plant endemic to the Mediterranean that forms dense underwater meadows. These meadows are crucial to the ecosystem, since:
- They provide habitat and food for a great diversity of marine species.
- They protect coasts from erosion.
- They improve water quality by producing oxygen and absorbing CO2.
IMPORTANCE OF ANCHORING RESPECTFULLY
Irresponsible anchoring can cause significant damage to Posidonia meadows.
The anchor and chain can tear the plants from the seabed, destroying years of growth in seconds. Therefore, it is essential to follow sustainable anchoring practices.
5 Tips for Anchoring Respectfully in Mallorca
1) USE MOORING BUOYS
Many protected areas of Mallorca are equipped with mooring buoys that avoid the need to use the anchor. Look for these buoys and use them whenever possi
2) Consult Posidonia Zones Maps
Before anchoring, consult the maps that indicate the Posidonia areas. These areas are generally marked and can be found in many nautical guides and mobile applications such as the digital nautical guide provided by Balearic Marine Cluster that includes more than 250 beaches and coves with useful anchoring information, including a Posidonia map prepared by IBANAT and information on the 8 buoy fields of PortsIB.
Another option is the GOIB viewer that will help you find the best anchorage. The delimitation of the fields and the most recent mapping of posidonia meadows are available in the viewer of the application https://ideib.caib.es/posidonia/.
3) Anchor in sandy areas
If buoys are not available, be sure to anchor in sandy areas, away from Posidonia meadows. The sandy bottom is more resistant and less susceptible to damage.
Also, calculate the anchor position and chain length. Take into account the length of the boat and the intensity and direction of the wind.
4) Use Respectful Anchors
There are anchors designed to minimize the impact on the seabed. Consider investing in an ecological anchor that causes less damage to the seabed.
The longer and windier the anchor, the more chain and the farther away from the meadow it should be anchored to avoid damaging the Poseidonia. When raising the anchor, make forward gear to raise the anchor vertically reducing the erosive risk of the anchor and chain on the seabed.
5) Respect Local Regulations
Be informed and comply with local regulations on anchoring and protection of Posidonia. Local authorities often establish specific rules to preserve these meadows.
BENEFITS OF PROTECTING POSIDONIA
Protecting Posidonia is not only crucial for the environment, but also enhances the nautical experience in the long term. Healthy meadows ensure cleaner waters and richer marine life, making Mallorca an attractive destination for sailors and tourists.
