Saw a guy going out of sandwhich tuna fishing (i think for his first time ever!) in a 27 proline. That would be tough, but once you get the tuna to the boat, i think it wouldnt be to hard to gaff him...Throw the rod in the holder, grap the bar and stick a gaff in him, sounds simple
If you believe this you have A LOT to learn. That is where many fisherman have gotten hurt and even killed. All it takes is one thing to go wrong and youre in a very bad predicament.
