Boarding pike? What is it?

[M ELEY]

Hmmm, yes, it still could be a logger's pike, but the examples shown have ends that could be deeply embedded in a pole for moving heavy logs. Our example just has a smooth tang and probably, as already noted by trenchwarfare, couldn't pull much weight. As a simple gaff hook spike, it would have been used mostly to retreive lost lines and to pull a guide rope over for securing a craft.
