Our boat has a dedicated 20-amp circuit that supports 1,800 watts. We installed an 1,800 watt induction cooktop which we very much like. Boils water quickly but still can simmer at lower power levels.
110 V electric is usually limited to 1500 Watts. Similar to any electric frying pan. Your wife probably hates the slow heat up and low heat of the present stove. Check the wattage of the burners on a new stove unfortunately they are still limited to 1500 watts so there wont be a difference with new. You may need to rewire to 220V.
