Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Edited from to 1/4th 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!!

This is a marvelous example of a CHB 42 Europa which has completed a major restoration for the last two years and is shed kept and ready for a new proud owner. The owner is a diesel mechanic so the engines will pass inspection. This is a classic Taiwanese trawler with beautiful woodwork and joinery throughout. Very spacious two stateroom layout, two helms one big head. The bridgedeck has lots of room and great visibility. Ask about freshwater moorage , also a 2020 70×29 boathouse complete with suite available. There is a bowthruster for ease of docking and handling in tight spaces. Westerbeke 8 KW genset , 6 x 6V house , 1 x 4D start and a dedicated group 27 genset battery. Xantrex 3000 chrger/inverter with display, Espar Hydraunic diesel heat, Comnav auto pilot, Furuno radar, Furuno GPS/Fishfinder, 30 amp shore power, reverse polarity indicator, Fireboy engine room system, Nova Kool fridge, Danby microwave, 3 burner propane stove/oven, Avon 310 Rib with 15 merc, 2 anchors , lofrans windlass.
