Just to let folks know what the reason for all the madness is.
Note the crack
Here's the good news. That's not mine
. Its a plate from a Irwin 43 out of Norfolk Va that the surveyor who shot my thermal pics is currently working.
The left is the bottom - you can see the weld where the bottom horizontal bar would be - on my boat that would be directly under the heavy (yellowish) tape - the only part of the chainplate actually sealed in contact.
