How do you determine your mast height?

Mast height is almost always measured from the water. But to be sure you know the how high the top of your mast is from the water, measure the actual height of the mast from the deck to the top of the halyard (tape measure) and then add a foot to account for the sheeve typically being below the actual top of the mast.

How do you find the height of a mast?

If the dowel looks a bit shorter, simply scoot the dowel up on the knot. When you finally set the dowel so that it is the same height as the tallest item on your mast, simply add this distance to your messenger line (or true mast height if you calculated it) and this will be your actual mast height clearance.
