Best Microwaves for Boats

A boat galley is among the most space-constrained kitchens anywhere. Most marine microwave spaces top out at 17 inches wide — and depth and height are equally tight. The models below are 17 inches wide or less, making them the best candidates for a marine installation. Many boaters also run on inverter power, so wattage matters — aim for 700W or 800W to keep inverter draw manageable.

• ✓ Marine spaces are rarely square — measure width, height, and depth independently. Don't rely on manufacturer "fits most RVs/boats" claims.
• ✓ A 700W microwave at full power draws about 10–11 amps at 120V — factor this into your inverter or shore power budget.
• ✓ Mechanical dial controls are more resistant to salt air and humidity than membrane touch panels in the long run.
• ✓ Secure the microwave against movement — most compact models can be braced using the side ventilation clearance space.
• ✓ If running on a pure sine wave inverter, almost any microwave works. Modified sine wave inverters can cause some models to hum or heat unevenly.
