Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Unedited at normal speed. I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

The ultimate dream of living aboard or going offshore comes to all sailors, so the timing of "Inevitable" being listed for sale may be just the answer you are looking for! Built and maintained to a very high standard, this 2-cabin 2-head centre cockpit vessel does not disappoint when it comes to exceptional living accommodation matched with distance capable sailing performance. Topsides this ketch rigged sailing vessel has classic lines that are timeless. Wide unobstructed side decks two-tone in colour provide an updated look that is visually eye-catching. The centre cockpit is large, offering exceptional visibility from the helm and protection from the elements by a full enclosure that is perfect for off-season sailing.

Down below, beautifully finished in teak the interior space is just lovely offering a space that is warm and inviting which can sometimes be lost in larger vessels. A v-berth cabin and enclosed head are located forward with  the spacious salon and galley located mid-ships. The aft cabin with a large centreline berth and ensuite head with shower are accessed through a starboard side passageway for maximum privacy making this a perfect boat to entertain guests or clients as a charter.

Du kurbelst an der Rollanlage – und trotzdem bewegt sich die Genua keinen Zentimeter. 😤 Oft ist nicht „die Rollreffanlage kaputt“, sondern ein verstecktes Detail an Schoten, Profil oder Fallführung. #segeltrimm #liveaboard #hafenkinotechnik
