Just curious, but have you ever seen one on a boat smaller than 39-40'? Not being rhetorical, just trying to keep up with the newest latest and honestly don't know the answer and thought you might. In my maybe outdated experience, the system usually is found on boats that would require either a mainsheet winch, or a pretty large mainsheet block system, the primary advantage of the German system being speed of operation (trimming, gybing, leeward mark roundings, etc...) and the mechanical advantage being provided by two winches. The German system also works best with relatively long and efficient traveller system.
To the OP, if you're boat was originally rigged with end boom sheeting, that's what the boom section was designed for. It may not be beefy enough for a mid-boom system.
