We were given a single photograph and some words to help us identify this item. While it appears that the poster is holding it with only one finger, the text tells us that it is four or five pounds in weight. Not what a typical float would weigh. Many of the modern floats are made from a hard syrofoam material and weigh practically nothing.
If we called something a 'bouey' that means it has boyancy and will float. Using the word 'float' would also indicate that it can float.
The fact that a thing/item can be somewhat buoyant, meaning that while it may not float on the surface by also will not sink to the bottom of the ocean makes sense that this unknown item can be a weight to control the net
under the water.
Looks like
@RickCorey got it right back in post #920046 when he said... "a rope could thread through those holes". But it wouldn't float, so it isn't to hold a net up. Maybe weights for the bottom of a net, to hold it down?
Good to know that the unknown item has now been identified.
