Cameras and Whistles

The forward looking camera (with 72 IR LEDs) camera today. It's big but a perfect color match, i.e. the same white, as the dome camera. Here's a drawing of what it will look like. I was concerned the starboard shroud would interfere with the IR camera but the drawing shows it will clear easily. We'll probably see the topping lift in the aft-looking camera but it shouldn't be too bad.

 Got the Kahlenberg #116 and #117 whistles plumbed together today. The combined sound is great. I'd thought that valves at each whistle's inlet would be required to 'tune' the circuit. It turns out that leaving each ball valve wide-open is perfectly acceptable. I'm leaving the ball valves in as it allows flexibility. The next job is to pull the stack, mount the compressor and mount the whistles.

With the stack off it'll be easier to clear all the silicone out of the wire chase (the one through the salon ceiling and into the stack). To keep water from leaking into the headliner a fiberglass dam will be built around the penetration.
