“Gaff” is a big hook on a stick used to snag fish aboard a trawler

“Gaffe” is the word you are looking for. When you look up Gaffe in the dictionary, Joe Biden’s picture is found there.

Thank you. I am one of those who still type with 3-4 fingers and backspace more than I key.

"Trawler" is a boat that drags a huge net through the water, hoists the bag end on board with a power block and dumps the load of fish on deck, thereby a gaff is not used.
I believe you are looking for the word "Troller" where salmon or tuna are caught on baited hooks or artificial lures, and usually brought aboard with a gaff hook.
As to my original misuse of the word, guilty as charged :>)
