To add to Mary's post

It is also less likely that you will forget a crucial step if you have a set procedure.

You will be less likely to unstep your mast without the base pinned etc. (Jousting your help that just unpinned the forestay/bridle)

You will be less likely to throw the mast up (and back down again) if you arent thinking you did pin off both shrouds, didnt you...?

You will be less likely to drag the forestay wire down the highway if you always tuck it thru the tramp lacing in a loop (prindle 16 right?)

You will have more luck hooking the jib if you set the hook the same (right) way each time after untwisting the halyard

You will find the halyard if you always keep it the same spot, And generally have more fun and time on the water.
