Today I was looking for some batten tensioners for my blokart sail.
I found one suitable for the task but this would require to change to a round batten rather than the standard rectangle type. One observation was windsurfing battens are considerably stiffer than standard blokart battens.
Here is the batten and tensioner borrowed from the windsurfing sail.
Here is the tensioner installed. You can see my modified standard type tensioner still attached.
Here are a few other batten tensioning systems I came across today.
