When I was researching gaff lengths, and there's been some discussion on this forum before, I found that there was a lot of personal preference involved. Some guys thought about a foot long was just right, where others liked three foot or so range. When I built mine recently I ended up at 32", which mostly had to do with where I cut my calcutta to get a clean finish.
Gaff hook size is another consideration. I went 2.5", but those who catch the really big stuff seem to like the 3" gaff hooks.
