Nuts and bolts guide to rigging : a step-by-step guide to the rigging of rowing equipment for beginners and intermediates : a manual for Concept II, Empacher, Kaschper, Pocock, Schoenbrod, and Vespoli

Essential for anyone who has ever put hands on. Well structured, easy to understand, and useful for beginners and experienced rowers alike. It goes through how to do specific tasks with a boat, what tools you need, etc. Really useful for underfunded crews who don't have a dedicated boat tech, and who have to find ways to do things themselves.

Get the spiral bound edition if you can, it's easier to use it while rigging that way.
