Correct Anchoring Procedures

  1. Avoid Neptune grass meadows when anchoring. With the wind at your bow, stop the boat above the bottom of lighter colored (sandy) sea bed and then pitch the anchor.
  2. Slowly roll out an anchoring chain or rope, which must be at least 3 times longer than the anchoring depth (4-6 times longer for anchoring depths up to 20 m).
  3. Reverse slowly backwards to tighten the chain/ rope and make sure the anchor is holding.
  4. Keep in mind what the radius of the boat around the anchorage point will be under the influence of wind and sea currents.
  5. When you leave, head over to the place where you dropped anchor and simply lift it up.

It is important to know:

Inadequate anchoring, dumping waste water, throwing garbage, being noisy, speed boating and various other activities will significantly harm the natural environment.

Each of us should take responsibility for our actions in order to stop the causes of irreparable damage.

Make use of good anchoring techniques and materials that reduce its negative impacts.

Equip your boat with a waste water system.

Dump all waste from the boat into proper containers, not in the sea.

The permissible cruising speed for vessels is up to 5 knots (9km / h).

If you find any caulerpa seaweed (Caulerpa cylindracea) on the anchor or chain, please throw it into a trash bin, not into the sea.

Anchoring is permitted in the ports of Polače and Pomena.

The use of underwater ambient lighting is prohibited.

Vessels at Mljet National Park are obliged to have an entrance ticket for the vessel.

A vessel ticket is your contribution to nature conservation!
