Do you plan to cook anywhere you won't have the shore power available?
An electric unit is convenient and easy to use.
It's also much less messy, and much less dangerous than a propane, white gas, or alcohol stove.
But you have to have that shore power, unless you add a generator.
And even with a generator, a 2000 Watt generator will run one 1200 Watt "burner" and something else small, but not two burners.
If it were me, I'd keep the alcohol stove, and just buy a portable electric cooktop and put a nice cutting board over the alcohol stove (The Origo already has one).
That way, you still have the alcohol stove for cooking on the hook, and have the electric one in port.
If you take the alcohol stove out and install a permanent/built in electric stove, the boat may loose some of it's resale appeal to potential customers when you decide to move up to a larger C-Dory or get serious "two-foot-itis" and purchase that trawler or tug someday!
My Sea Ray has an electric/white gas stove, but I cook outside anyway on a portable propane stove to keep the cooking odors outdoors. The thought of 1 pint of white gas 7 inches below a couple of hot electric burners in a little copper tank can be pretty scary if you think about it! The previous owner of my boat was so afraid of it he cut the 120 VAC wires to disable the electric part(!) I re-connected it, but have never refilled the reservoir with gas, though I keep a gallon of it under the sink (!) There's enough energy in that can to raise the whole 26-1/2 foot, 8,500+ lb. boat about a mile into the sky!
I have propane in my CD-22 with a Force 10 Cozy Cabin heater and a three burner Wedgewood cooktop. That solves both the heating and cooking issues, in and out of port. Just use the propane with judicious care!
Good luck with whatever you decide on!
