The HDMI monitor part should work out of the box with any screen. The tricky part is the Touchscreen. You need to find a touchscreen that has drivers for Raspberry. Also, most of those that do support RPi over USB are single touch only, but since you do have a wireless mouse, once you have everything set up properly, for normal use during sailing you shouldn't need right click anyway but for a few occasions in OpenCPN (e.g. editing Dashboards). The only multitouch LCD touchscreen I know of is the official 7" 800x600 Touchscreen LCD from the Raspberry Foundation (somewhat multitouch, in that you can assign right click to two finger touch) and that one connects via the ribbon cable directly to the RPi board.
I have ordered this one myself: https://www.aliexpress.com/item/7-inch-R....71.SBqF3J but I plan to mount it on a dashboard at the helm station (I have a center-cockpit sailboat with pilothouse, so this is the best place to mount mine). A 10" model by the same manufacturer is this: https://www.aliexpress.com/item/RPi-Disp...b9b3&tpp=1.
For a 10" monitor with proper case and base you can also check this one out http://www.lilliputuk.com/monitors/hdmi/fa1012/ (apparently it works on RPi: https://www.youtube.com/watch?v=dXCiMtwKuRs)
Once I receive mine I will let you know if it is worth buying or not
[Edit: Yikes!!! I just saw the price on the Lilliput screen, 239.00€!!!!!! - that is crazy! If you really need a bigger screen, this one (http://www.chalk-elec.com/?page_id=1280#...ry=3094861, https://www.youtube.com/watch?v=eSKmG1VFA4w - 14" 1366x768) seems like a better deal - even without a casing
