[Tagging] nautical channels

It looks as if OpenSeaMap does map the seamarks that delimit the navigation
channel, but not the channel itself.
The reason I am asking here, is that I detected by chance that navigation
channels in the Venice Lagoon [1] have been tagged as waterway=canal, which
to me seems not correct, or at least not covered by the wiki definition.
This is most likely due to the fact that the English words "canal" and
"channel" both are translated in Italian as "canale". In Italian artificial
waterways are called "canale", on land and on water.
Before raising the issue of a (widespread) retagging with the local
community, I wanted to find out what better tagging, if any,  is in use for
such objects outside Italy. If no such tagging exists, then an alternative
might be to extend the meaning of the waterway=canal in that sense, and
document it in the wiki.
