The problem with Touch screens on boats is that in a seaway, you tend to touch them a bit hard at times. All it takes is one brute with long dirty fingernails to do permanent damage.
With high humidity and a salty environment
, they will smear more and if cleaned harshly, will wreck the screen
These are what the commercial
guys found out so general preference is for replaceable membrane keyboards.
Personally, as the captain
, I don’t like hands waving in front of the screen
when I am observing something.
