I'm not convinced that is as big an issue as you think (if it has been well designed ergonomically) - do you randomly push buttons on handhelds in choppy conditions?
Do you know where the moisture is coming from:
- sea water? - where/how are you mounting them and where is it getting in
- rain water? - where is it getting in? does the boat have a cover etc?
- condensation? - look at the ventilation of the boats in storage?
some people resort to butchering their radios and adding silica gel inside the casing (search for a post by biffer I think with tips on special screws for the job IIRC?) - if they are out of warranty and the display is fogging but functionally OK this might be worth a try before splashing the cash on replacements.
