This is probably the most fascinating video you will ever watch about wood. Seriously.
That's just the beginning though. This video comes from Shipwright Louis Sauzedde. He's passing along an incredible body of knowledge on YouTube, and his channel is totally worth checking out. There's also how to bottom paint your boat, a look at a giant ship saw, and a whole series on repairing an old Herreshoff.
Between this and Casey Neistat, I have no idea why you'd ever need cable. I'm hooked, and will no doubt have Tips from a Shipwright to thank when I finally set sail on my own Herreshoff.
