Barges and penichettes are flat-bottomed displacement vessels built for navigation on rivers, canals, and lakes, operating at low speeds — typically 8–12 km/h — consistent with inland waterway regulations across Europe. Traditional commercial cargo barges have been extensively converted for leisure use; penichettes are a purpose-built leisure variant, smaller and more manoeuvrable than full-size barges, available primarily through charter operators.
The flat-bottomed hull form and shallow draft — typically under one metre — allow navigation through the shallow, lock-controlled waterways of France, the Netherlands, Belgium, and Germany where deeper-drafted vessels cannot operate. Interior volume is the primary advantage over other inland cruisers: full standing headroom throughout, permanent double cabins, a proper galley, and large aft and forward decks are standard. The trade-off is speed and sea-keeping — barges are not coastal vessels and should not be taken into tidal estuaries or open water without specific design provision for it.
Steel is the hull material of choice for full-size barges, providing structural durability against lock walls, debris, and the occasional grounding on a shallow canal bed. Penichettes are GRP. Propulsion is a single inboard diesel with shaft drive; engine outputs are modest relative to hull size, as waterway speed limits make high power unnecessary. Bow thrusters are common on larger barges to assist in locks and tight manoeuvring situations. Many converted barges connect to shore power at permanent moorings and are used as liveaboard residences as well as cruising vessels.
