It appears that I have a problem with the inmast furler on my C375. From the surveyors report, they had used alloy rivets.
Attached is a photo of the damaged bit.
I am waiting to hear what the local Catalina agent says about the problem.
Have any other 375 owners had a problem? Maybe its worth checking on your rivets.
Cheers

I looked up Selden Manual for Furling mast TYPE RB Mk II/RC Mk II and found a section on "Checking luff extrusion tension prior to stepping the mast" The threaded part I see on your picture looks like it is the tension adjuster. From an exploded view of the assembly on page 13 in Selden Spare Parts List manual, the rivets would be item D11, pop rivet LD639. No mention is made of the material used.
Could it be the adjuster was tightened too much and putting too much strain on those rivets? The threaded portion of item D9 (tensioning screw) looks all the way into the locking tube on your picture.
I just finished tarping our boat for the winter but I will be adding this to my list of checks to do in the spring.
Let us know what your Catalina agent comes up with too.

That is a very thin piece of material to carry any load and if the aluminum was weakened from contact with the steel allow rivet, I could see it breaking very easily.
Francois' observation about possible over tightening could play a big factor, too.
