The boat manufacturer had installed a solution on one of their yachts where all the electronics were connected to a single network on-board. All the key functions, such as steering, acceleration and gear changing were connected to the same system.
With electronic signal transfer between the throttle lever and the engine there was none of the inertia in the lever that most people are used to, and which contributes to the experience of running the boat. There was quite simply no resistance, and some of that "boat feeling" disappeared.
The subcontractor was given the task of manufacturing a throttle lever with the right feeling. They in turn contacted us.
Our recommendation: Hot glue a friction material with a high friction coefficient to a plastic carrier and you will get an excellent product with the inertia and feeling you are looking for.
With the right materials and processing, in a cost-efficient and automated production process, we helped the customer towards a very good component at the right price.
