Picked up new traveller and solid vang.
I'm am very comfortable with installing new traveller- filling old holes, drilling new, backer plates and so on.
I need to find a resource or two regarding the instal of my solid boom vang. I'm uneasy drilling into the mast without a solid plan. Any advice on procedure or steps would be appreciated. I wouldn't take issue with even the most rudimentary advice.
I have been told that I should install the vang with a rate of 80% compressed , with the boom at a right angle to the mast....ideas?
