A 
Portage is a location equipped with suitable aids to allow boats and other watercraft to be transported between two waterbodies when connection by water is not possible (for instance weirs, rapids, or just intervening land). Historically they were widely used, but are not as important as in the past.
How to map
Set a way 
along the portage connecting it at each end to the two waterbodies. Add the tag waterway=portage.
Examples
Punt rollers at Oxford (Parson's Pleasure) and Cambridge (Mill Pond, Newnham).
See Also
Portages used by whitewater sport participants are more usually tagged whitewater=portage_way, whitewater=portage or portage=yes, along with highway=footway or highway=path. In practice these are like footpaths with enough width & headroom to allow kayaks and canoes to be carried without snagging on vegetation.
Ship or Boat lifts used to move craft between two levels in a waterway system in general should be mapped with the appropriate tag.
Boat lifts in marinas used to lift yachts in and out of the water should also be tagged distinctly.
