One of the boats I sailed recently for a couple of months had an IEI TDM waterproof industrial touchscreen in the cockpit
and an ARK 3202 industrial 12V PC with dual video output and another 12V monitor
inside. The touchscreen monitor
was not advertised as sunlight viewable, and indeed the visibility was sometimes poor. Otherwise it was OK.
The touchscreen was OK with OCPN, but with Navsim (lots and lots of tiny icons) it was very hard to use...
