I use Corelle dishes on my boat. I bought one of the full sets of 4 place settings, which includes some ceramic mugs. Haven't broken any yet, but I also haven't subjected them to any forces that could break them... none have fallen on the floor. These also have the advantage of being oven safe, which is a big plus because I don't have any ovenware. Sadly, I do not currently have any wine glasses, so I drink my wine out of either a mug or a solo cup. I think I might invest in some fairly thick stemless wine glasses. This website talks about some good ones: Boat Wine Glasses | The Boat Galley
I'm still looking for a good martini glass. I think I might go with a stemless one of those too, or maybe stainless (or stainless AND stemless, to deal with the top-heavy problem inherent in martini glasses). I need my martinis.
