Retain the top half of the block as this will provide
a level surface inside the hull to tighten the nut
against.
7. Check the bottom half of the block against the
hull to ensure a good fit.
Ensure that the block runs parallel to the
centerline of the vessel.
8. If there are gaps between the block and hull then
use an appropriate file to shape the block until a
precision fit is achieved.
