From gravel barge to passenger vessel – the history of our party boats

Waterways and waterbodies have been important transport routes for goods ever since the middle ages and before. Prior to the introduction of railways during the 19th century, local transport of both industrial goods and passengers usually involved boats travelling Lake Zurich.

Locally known as ‘Ledischiffe’, in Central Switzerland sometimes also as ‘Nauen’, these types of vessels are still used to carry bulk freight (often grit or gravel) across lakes and along rivers. JMS-Gruppe has in recent years converted two such former cargo boats, both with a service record of well over a hundred years, into passenger vessels, now being operated as party boats for rental.

History Slide1


LS Stäfa is constructed as a wooden boat in Uerikon, Lake Zürich.

History Slide2


The ship was built in wood by the Sutter shipyard in Meilen.

History Slide3


The boat becomes the property of the newly founded Müller & Cie. Schmerikon, which will eventually become Johann Müller AG.nDue to its flat loading floor, the boat is predominantly used to transport stone blocks and quarry stones.

History Slide4


The boat is converted from a wooden into a steel vessel at the Ziegelhof boatyard in Schmerikon.

History Slide5


LS Stäfa loading 200 tons of sand and gravel at the Grynau plant.

History Slide6


The stone ship is only used for passenger transport and is equipped with a tarpaulin superstructure.

History Slide7


LS Stäfa is re-invented and re-purposed once again, this time from a cargo boat for gravel and sand to a state-of-the art party and event boat.

History Slide8


In January 2019, LS Stäfa is lifted into drydock for a complete renovation. Renovated and restored to new splendour, the boat is re-launched in April 2019.
