Has anyone tried to use a mirror and bubble level as Richard Hubbard
described in his book "Boater's Bowditch"? He describes using a thick glass
mirror with a plywood back and thumb screws for leveling. What is the down
side of this and what kind of errors would you expect? Is the error all in
the level or are there others? Thanks.
