5.5 Z 5 "Sim-Sala-Bim" - original length - 21.03.2021 by Kaspar Stubenrauch
The boat was built with an original overall length of 10,151m, showing its positive yacht-stern, in a picture from 1953. The measuring certificate from 1959 is then presenting an overall length of 9,403m. Later another bit of the stern was cut off. The idea to bring the boat back to its original LoA measurement is on the table.
5.5 GER 80 - future development - 16.12.2017 by Kaspar Stubenrauch
The boat has been sailing on Lake Zuerich over the last years. Now it has arrived on the shores of Chiemsee in Bavaria as 5.5 GER 80 and will be going through a thorough restoration and a bit of body slimming - in weight - after which "Simsalabim" will return to the 5.5mR racing circuit.
5.5 SUI 5 "Sim-Sala-Bim" - the Boesch boat - 21.08.2012 by Kaspar Stubenrauch
This is the only 5.5m boat ever built by the famous Boesch boatyard. After her debut on Lake Zurich and many years of sailing on Lake Constance - there out of Ueberlingen and Arbon - the boat has been for some time given to sailors on a loaner basis for racing, but will now be again enjoyed on the waters of her origin.
SUI-005a and SUI-005b - 29.06.2008 by Site Administrator
There were two different boats to wear the number SUI-005.
"Sim-Sala-Bim" will stay with SUI-005a.
The second one is "Vision II" who was originally GBR-021 and became then SUI-005b and NED-018. Please visit for further details.
As soon as we'll have implemented the database with the possibility to have extension -a -b, etc for the double numbers, we'll clarify this.
