Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). 1/8th speed (15fps) and improved video performance because somehow Youtube cropped the last frames of the other videos (?) 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!!

► Full report in Multihulls World N°201: https://www.multihulls-world.com/articles-catamaran-trimaran/cmc-race-and-rally-2025-the-fun-rendezvous-for-multihulls ► For its sixth edition, the CMC hasn’t set the record the number of participants, with 23 multihulls registered. On the other hand, the atmosphere both on and off the water has never been better. The trade winds, in fine form at between 20 and 25 knots, undoubtedly had something to do with it... The five entrants in CSA 1 enjoyed superb courses towards Saba, Saint-Barts and Anguilla. The HH66 Lee Overlay Partners (ex Nemo) put on a great show, impressively flying a hull and, above all, peak speeds pushing 30 knots. The Gunboat 72 Layla was not to be outdone, with her GPS recording a top speed of 24.5 knots. The La Grande-Motte shipyard's first flybridge catamaran won the overall race on corrected time. The Diam 24 fleet was of course severely tested by the choppy conditions, but there too, they put on quite a show. In this fury of spray and exciting runs, the crew of Anomaly came out on top, leaving their rivals with no chance of a rematch. For the past two years, the CMC has been running a second division called Rally. This year, the 9 participants were accompanied - and looked after - by our Marketing Director Gwen Dorning. The fleet headed to Phillipsburg, where beach games were organized on the first day, followed by a fireworks display in the bay, then headed for Anse Marcel and finally Saint-Barts - a dream program which is already scheduled for next year, with dates running from January 29 to February 1. ► Become a FREE SUBSCRIBER to Multihulls World's YouTube page now - https://www.youtube.com/c/MultihullsWorld ► Log on to our website to discover over 600 multihulls tests!
