The Elblag Canal in Poland has a different sort of inclined plane for lifting a boat to a higher level of a canal.  This works by manoeuvring a boat onto a submerged platform which has wheels and runs on a track. Once anchored on the platform the whole thing is hauled up and inclined plane into the higher level canal where again the platform is submerged and the boat can be freed to go on its way. The photos below show the process.
