Can you see the inside of the hull? The patch may be a reinforcement for a
damaged section of the hull. You could be opening up a "can of worms"

If you do not need to remove this patch do not do it. If it is a must for
you to remove I would use abrasion or lever action. If prior to applying
this patch the hull was not de-waxed or clean with chemical agent chances
are that the bonding is not 100%. I you can find de-lamination between
the hull and the fibreglass patch I would insert a thin oak wedged
scrapper and push it out gradually. If this fails I would use a auto
body file mounted in its holder to shave this patch away. Failing to this
I would use a dual orbital sander with extreme care as to not de-formed
the shape of the freeboard.
The freeboard will have to be faired out with premium marine filler,
painted and blended with the rest of the color.
Maybe someone has better ideas?

My boat has a 3'x3' patch of heavy non woven matt fiberglass on the hull
from the gunnell to the waterline.
It was used to protect the hull as lobster traps were hauled into the
boat.
Its ugly.
The hull is balsa cored.
What is the best way to remove it?
