It's been a busy summer of learning; sailing, boat life, and making plans. This video covers the first actual work on the boat! The shaft log was close to failure, which could have sunk the boat. The shore power feed gets upgraded to 30A, and a new 20A circuit is added for more reliable aircon in the summer heat. There's a little treat for those who watch to the end.

![Lightning & Sailboats, Beyond TE-4 - Ep. 124
For over four months, I have been working on a new lightning protection system. I am still learning, but with spring arriving, its time to get back to boat work.
In this video, I talk about what Ive been learning, and give hints at what will be coming as the lightning protection system and the associated paper takes shape.

![Ep. 88 - Damaged Battery Test Results
Edit: Sorry about the audio. I accidentally turned the mic volume down, and tried to boost it in post. The audio seemed OK before I uploaded it. It seems youtube somehow compresses or somehow edit s the audio and makes it break up more.
In this video, we recharge and then discharge the battery with the cell that fell to 2.0v. The test results were less than optimistic, but not in a way I expected.
