To me its a classiccase of too much weld causing a over stress sharp stress raiser.
It looks like the 2 plates were joined with a packing plate with a gap between the side plates.
2 comments the pcking plate does not need any welding and only at the top of the tank not down to the gap in the tang.
there is no need to the packing plate as the bolt through the mast will hold both tang plates vis the top hole.
On my current boat I had a similar setup with cracks I made new ones from thicker material but did not weld the 2 side plated together.
As no welding not stress riser so no racks.
The real issue is that welding between the side plates is not possible so a stress riser is unavoidable.
In correct design as people think the more welding the stronger the fitting which is not always the case
