John, thank you for your detailed reply. I appreciate your thoughts and must say that I agree with your concept, except...
When cruising, our Mac performs multiple duties, and among the many is very often being carried ashore to an Internet cafe or telephone (yes, still use an acoustic modem sometimes!) when there is no WiFi available at the boat. Dragging a Mac Mini and a separate display to shore would unfortunately get painful in a hurry (I'm from the generation that lugged the original Macintoshes everywhere for years).
I did take my 20" iMac onboard last year for our two-week shakedown cruise before setting off, and the size and brightness and viewability of the display were awesome, as was its power consumption. Charts on a display that large are incredible! Ended up not taking it with us because of its physical size and weight.
I guess I could get a great separate display in addition to the MacBook and leave it onboard, but I'm constantly trying to declutter the main saloon table which doubles as the navigation station and (only when passagemaking) already has on it the radar, VHF, SSB, Pactor Modem, AIS receiver, two GPS, SeaTalk Graphics Display, RS232/NMEA/SeaTalk converter, satellite radio, two Macs (the old WallStreet PowerBook running OS9 primarily used for weatherfaxes but also for NaviMaQ as backup for GPSNavX), and an inverter and a couple of small power supplies and a few RS232/USB converters - and all that wiring... even more cluttered than shown here: :roll:

Nevertheless, the original question stands: "glossy" or not?
John, if I understood you correctly your vote would be for the glossy because of its greater brightness (due to the absence of the attenuating anti-reflective coating) :?: Thanks again for your input. JoeS.
