Nice fish! Sorry about the "disaster".
I hope I'm not hijacking your thread, but what's the right thing to do if you get a cannonball snagged? I'm hoping to try downriggers for the first time this year and have never seen them used. Do you set the clutch loose enough so that cable will be spooled off until you can react? Is there any way to try and retrieve a snagged ball? Do you ever just give up and cut the cable? Could a snagged cannonball break your riggers or rip out the mount?
Sorry for all of the questions, but your post got me thinking that I better start figuring out what I would do beforehand in case of such an emergency.
