Bonjour Bernhard, Long run but short distance 😁 Besides this, definetely a wonderful boat with a lot of lovely details and a great efficient pump, good fo the autonomy. Your whistle looks like the one I bought recently to Microcosm, where do you buy all your valves, nuts, etc... ? Your next challenge, if you accept it woll be to install a functional Windermere kettle and this message will not disapear after 5 seconds 😉 Amicalement, Raphaël
