The Holy Loch is located on the central western coast of Scotland. The body of water was so named because sometime in the Middle Ages, a merchantman carrying a cargo of sand from the Holy Land sank in its cold, dark waters. According to local legend, the sand was to have been used for the construction of a local church. The Loch is surrounded on three sides by high hills providing a safe anchorage from the rough weather that is so prevalent in this area. The tender and submarines were moored in the center of the Loch for a very good reason, Security. By not mooring the ships to a pier, it made it far more difficult for terrorists or enemy agents to attack.
