Views from the Intercoastal Waterway

I spend a lot of time on the water doing boaty things like endlessly turning circles, running for my tool kit to overcome some nautical mechanical or electrical travail, and pointing out to Bob he is now out of the channel and maybe he should turn to port if he doesn't want to buy new props. My camera is always at the ready if unusual sights appear, and they always do.

Garmin GCV Sonar Recording Movie Making

This little demonstration video turned out to be more of a challenge than I had anticipated, but in part it was my fault... sort of. The documentation didn't anticipate I would be dealing with three different Garmin 741xs MFD's, about 6 hours of sonar recordings archived on my computer from two of them, and a chart from a third. But with some excellent and very patient tech support from Garmin it all got sorted out. 

It also required some experimentation to get decent image quality. I started with the original very sharp recordings, played them back in Garmin's Homeport software. The recorded playback was captured using BB Flashback Express screen recording software. The newly created file was exported to a AVI format. From there the AVI clips were edited, and a simple soundtrack was created. The whole thing was then converted into a WMV format for upload to Youtube.

With each conversion you lose a little resolution. Aargh matey, I was in need of Dark and Stormies by the time I was done, but in the end I was happy with the results. It would have been better if the original recording format was a little more video friendly.

Keeping the legacy alive, installing the Raystar 130

It was dead period. No pulse, and its faded chalky pallor were indicators it had joined thems what's dearly departed. Its destiny is a pauper's landfill grave gently swathed in a plastic garbage bag along with the remnants of last nights Chinese food take out dinner.

The Raymarine classic C-80 is still in mourning, and something has to be done. It's currently a really expensive repository of non-moving electronic charts. There are two things that have to be considered. The old Raystar 120 GPS needs to be replaced, and whatever is selected, we have to install.

Signal K is afoot.

I wish to communicate with you!


I know the vast majority of you have never heard of "Signal K" and until recently I hadn't either. Signal K is a collaboration by several open source boating related software developers who have worked together to create a common data management framework to support their efforts.

This includes the open source CANboat and browser oriented Navguage projects. CANboat is largely dedicated to reverse engineering NMEA 2000 PGN's to allow others to access the specific data elements such as boat speed or wind angle.
