Good eye, I do believe there is some Tomfoolery aboard!
I know a boogie board when I see one, and that black and orange foam doesnt look like a piece of oil transfer pipe.
Also, I have caught hundreds of marlin, and have never seen one intentionally attack anything by stabbing it with the bill. The appendage is covered with rough sandpaper like texture, helps hold baitfish until it can be positioned for swallowing, is not a stabbing tool.
I have seen accidental stabbing of the boat and, on one occasion, the gaff man, with the bill, at the transom when the leader is short and the fish
is disoriented, however this isnt normal feeding behavior.
If you blow up the photo
, the stripes in the top left photo
are some kind of wrap around the outside of the pipe, the orange looks to be an internal ply. (like in a boogie board)
Black and orange is a good color for Ono, black and purple and/or blue is a better marlin color, more closely resembles Skipjack tuna, top choice on the Marlin Menu!
These fish are capable of very high speeds, and the primary function of the bill appendage appears to be part of the streamlined profile that allows these speeds.
