Re: Spinlock rigid vang and am having difficulty with the lock/release switch.
Immediately after hoisting the main, and while it's still luffing and the boom is dancing a bit is the best time to go forward and push the switch to 'vang' mode..
Switch it back to 'topping lift' before dropping the main if you can.
