This article does not mean it is accurate....
It does hint of the ship not having been unloaded yet. (So ,would stone have been added to the hold yet?)
Mention of partial salvage too. (Note some bronze cannon pulled).
[It was Ribault’s four larger ships that were wrecked probably between Ponce Inlet and Cape Canaveral, and thus are of interest to expedition archaeologists. First was Ribault’s 32-gun flagship, La Trinité, owned by the crown. It was a galleass, a hybrid galleon-type warship propelled by both oars and sail, and a relatively small one at around 150-160 tons. It does not appear that La Trinité was unloaded before the storm, which makes it a particularly promising target for an archaeological survey, both due to the presence of iron detectable by magnetometry and the wealth of potentially preserved material culture.
A significant amount of munitions, armament, and supplies are listed on its 28 April 1565 manifest. Iron objects which are likely preserved include 20 berches (large faucons or falcons, a class of cannon); four chiens (another artillery class); 977 cannon balls; 300 iron pikes; 1,300 nails; 100 corsets of armor; 3,153 pounds of stock iron; two anvils; a large iron bowl; a sheet of iron; and a variety of small items including tongs, hooks, pincers, and other hand tools.
Some of the ship’s bronze cannon were salvaged by surviving crewmembers, but there is no other record of significant salvage activities taking place.
La Trinité was stranded on a sandbar for some time before succumbing to the waves, suggesting that the shipwreck may be preserved in a more intact condition than the other three, which broke to pieces in the surf soon after running aground.]
