During the «golden twenties» the company builds, checks and repairs sail boats, motorboats or rowing boats depending on the order.
The application of combustion engines as drives for boats increases. At that time Boesch takes the first steps with pure skimmers.
The son Walter Boesch developed the first fast motorboats with the principle Boesch-Horizon-Gliding which today is legendary. His wife Rösly Boesch-Jacober secured the commercial success of the company as a capable business woman and financial wizard. Because of the lack of gas and material due to the war Boesch concentrates on building sail and rowing boats.
Boesch celebrates it’s success with the following stars: Small racing yachts with a „Knickspanntrumpf“ produced in units. 1952 Boesch starts the production of bigger series.
