Vlog 118: Bob Cratchit November 30, 2017 May 31, 2020Engineering, Vlog 5 A bit of DIY and a product review in this video as I think back to when I was moored over the summer and took the cratch cover off, firstly to kill off the algae growing on it, secondly to clean it, and thirdly to re-waterproof the canvas.
