The Saint Louis (named for Louis IX of France later canonised) is a Luxemotor hotel barge built by Boot a Alphen in Holland in 1923. She was built as a bulk carrier and served in the Dutch seas and inland waterways carrying cargoes of grain and gravel until around 1985. At that time she was converted for use as a supply vessel in the port of Amsterdam using the name Supplier 2. In 1994 she was sold and then converted into a hotel barge.
