I've never even considered measuring such a thing. Probably because, for me at least, probably the most key feature to a Marine
Stove/Oven, is the thermocouple. A handy little feature which, if memory serves correctly, lets the stove shut down gas flow to a burner, on it's own, if the flame on said burner goes out.
That way, if you have to unexpectedly run up on deck
, or tend to something else while in the midst of some galley
duties, (knock on wood) the stove can babysit itself.
I'm not in the habit of walking away from the stove while it's on. However, sometimes it happens... due to unforeseen events
, etc. Though even then I endeavor to turn off the burners/oven I'm using as I'm scampering up the companionway
Thus, aside from the perk of the stove's being stainless, that's "the why" behind marine stoves.
If you can find a stove/oven which has reliable thermocouples, but isn't "marine" or stainless. I'd say go ahead and snag it, along with a set or two of a few key parts
I can happily pass on the stainless part, & given a bit of time, can likely figure out how to best gimbal a stove. Ditto on fitting it with pot holders on the burners.
PS: If anyone does happen to know of some brands of stoves & ovens which have thermocouples, but which don't come with the "marine" price
tag. Please be kind enough to post your findings.
As while my boat came with a Force 10, 3 burner with over, it still seems loco to me to have such items costing well in excess of $1k. And it'd be nice to know of other proven options. (I know... get off my heine & go look/do some digging).
