Marina di Valletta – this is the newest marina in Valletta, the clubhouse is still under development and washrooms are in a small trailer (but plentiful hot water). Because it is the “last addition” to the marinas in Valletta, there is a concern about the protection in the marina.

We have stayed in the marina in late April/early May 2018 and were very happy. We entered with 25knt NE wind and 2m swell and had no problems. Once past the entrance to the harbour, the waves calm down and there is plenty of space to take sails down before entering the marina. While on the dock, we also experienced 35knt W winds with no problem.

The marina has a great location, it is a short uphill walk to the old town or one can take a bus that stops very close to the marina. Prices are in line with other Valletta marinas, perhaps a touch lower but still quite expensive.

The Msida and Ta’ Xbiex Marina has a lot of boats, mostly permanent, but they are friendly and do their best to find a spot for transients. Price for a 13 meter boat was 40.31€ +VAT totalling 47.57€ per in July 2014 plus metered power and water. A city bus is conveniently located on the Ta’ Xbiex side near the embassies and is a deal for unlimited travel for 1.5€.

Stay included use of the Malta Yacht Club, a great place to hang out and drink “Cisk” beer for 1.5€. Transient berth seems to be at the jetty in front of “Black Pearl” restaurant, a large wooden trading schooner, out of the water, that serves as a restaurant.

This is a comfortable marina for a stay in Malta.
