Just a quick update on the research platform. I launched it on its final shakedown cruise into the ocean off the Central California Coast. Once out in the ocean, it completed a 30 mile circuit (15 miles straight out to sea, 15 miles back).
One reason for the final test is the addition of AIS for keeping track of other boats in the area that also have AIS.…Continue
Finally was able to get the project back into the water after a 2 month hiatus. I have been trying out different props. One is the standard manufacturers issue and the other has more torque. I launched during a flood tide with winds out of the East at 10 to 15 mph. Max speed was around 7mph with the tide (the wind probably wasn't much of a factor since…Continue

As the tide was going out, the current was about 3 knots. The bot did fine. There were plenty of settings to tweak and a few adjustments of the Pixhawk PID had things working smoothly.
Some takeaways from the test.
