I live in this universe, have lived and worked on boats since 1977 and
have never heard the term "lens" used for the proper term "Glass" in a
port. If we slack up on the little things.. then you open the door for
people to slack on the proper terms of the importamt things. On boats,
and for sure sailboat knowing the proper terms and names might keep you
from getting injured or killing someone. Crytal clear concise terms can
mean the difference of life of death.

But hey thats just my opinion, Please feel free to run your boat any
way you want to...
