Dutch wikipedia has some pictures:

Rollers are used in Cambridge & Oxford to move punts & other small craft round locks. This one has been mapped as waterway=portage but without other details This looks like a reasonable generic tag, but I think the actual mechanism associated with a portage should be also tagged. Additionally portage may generally apply to places where small craft are physically carried around rapids or other hazards (although whitewater=portage_way, portage & portage=yes all have much more usage).

Wikipedia supports historical usage of portage in a more general sense (rather than current whitewater sports usage):

Just an idea, but would leisure=slipway be useful here? It sounds like a similar structure. A slipway is for putting a boat in to or out of the water. What you describe is for pulling a boat out, and then putting it back in. Maybe something like leisure=slipway in combination with slipway=overtoom.
