In my earlier post, I wrote of the 11 Anchor Stocks that are currently in storage at the Malta Maritime Museum—and I described how they worked.
Among the 11 is the largest ancient anchor stock ever to be discovered!

This anchor stock weighs over 5,500 lbs [2,500 kg.] and is 13 ft. 6 in. long [4.1 m.]. A careful look at the left end of the anchor shows that it was not solid metal, but had a metal shell that encased a wood “soul.” (see below for what is an “anchor stock”)

Gordon Franz (see below) quotes the Museum Archaeological Report that this “enormous Roman anchor stock [was] found lying on the seabed 120 feet below the surface 300 yards off Qawra Point….” [CR=near Salina Bay]. It is dated from “the second half of the second century BC to the middle of the first century AD.” It “… most likely came from an Alexandrian grain ship” [CR: like the one Paul was being transported on? Acts 27:6, 27–29]. It should be remembered that the large “Alexandrian” grain ships could be 180 feet long! — Paul traveled on two Alexandrian grain ships (Acts 27:6; 28:11)
It was discovered near Salina Bay, on the NE coast of Malta. This is near two of the bays that are “traditional” candidates for the site of the shipwreck of Paul (Acts 27—28:10).
For a good discussion of the shipwreck, ancient anchors, etc., and a vigorous interaction with the views of Robert Cornuke, see Gordon Franz “Does the ‘Lost Shipwreck of Paul’ Hold Water? Or, Have the Anchors from the Apostle Paul’s Shipwreck Been discovered on Malta?”

Great photos with information on these anchors for Roman ships shipwrecked near Malta
Thanks Mark! The trip that you organized and led, following Paul from Shipwreck on Malta to Rome, was excellent!
How interesting!!!!!
