Sounds like a Bluefin to me
Fish always keep growing after you lost them My cod the other week must be 40lb by now
More than likely a good ray, that why they use the heavy gear down you way for the big blondes.
ref the anchor
I have a buoy on the end of my warp that does not pass through the alderney ring.
If we have to let the anchor go its just a case of releasing the knot on the cleat and letting the rope pay out all the way, then toss the small buoy over to trap in the alderney ring.
After doing this last time and struggling to pick it up , I now intend to move the buoy 10ft up the warp and put a soft eye in the end, so that recovery is simpler.
