There is nothing inherently wrong with using gate valves on a boat as a sea ****.
There are several inhearant reasons not to use gate valves where a Teflon seated ball valve is available:
-No definite position indication
-mating surfaces will leak if damaged
-takes a lot longer to open or close
-prone to jam on backseat
-damage from freezing more likely
-more corrosion prone (more wear surfaces)
-more parts involved (more point of failures, as in my case)
