We have MWs installed in both of our boats and find them invaluable when in hot and especially humid weather. They're quick and heat the boat less than than when cooking with the conventional range. We also use it when cruising for hot drinks, soup and the like. Most products can be cooked in the MW and use less overall energy. We too use it for a bread box, finding it lasts longer. We installed a toaster oven on one boat as well, but requires shore power or the genset to work properly and the story is still out on that addition. But there's something to be said for fresh toasted bagel or English muffin with a MW poached egg that's ready to eat in less than 3 minutes leaving little to no clean-up.
