I am at a loss to know why anyone would contemplate andAga
an aga sounds smart but having one in the house and knowing how hot it is in the summer I wouldnt dream of having one on a boat unless I could turn it off in the hot weather (ie alternative cooking arrangements) I am also aware that they are seriously unecological. We have a gas stove and a boatmans stove which I use sometimes, but for ease of cooking I would stick to gas (or deisel)
However its SUCH fun planning
Good luck
