Former eel barges of the Koninklijke Moedige Bootvissers (Royal Company of Brave Boat Fishermen) ply the Binnennete, giving tourists a unique glimpse into hidden picturesque places.
In the past, fishermen used these boats without engines or sails to fish for eels. At night, they drifted along with the tide. As they sailed, the square net was pulled up at an angle by the current. This caught any eel that were swimming upstream. Every 5 minutes the net was hoisted up with a pulley. Hence the name 'eel hoisting', a method that was unique to Lier. This method of fishing was banned in 1974.
The Brave Boat Fishermen converted the flat-bottomed boats and have been organising tourist trips with them since 1981. Their boats have the same shape as eel boats and are fitted with an electric outboard motor.
The current tourist boats do not have a number, but a name linked to the history of Lier or a typical character from Lier.
