I have a Magma Kettle standard size propane
grill/stove. Yes, I hear lots of complaints: parts
are expensive, doesn't work well on windy days, marginal temperature control, too small...but it works for us.
We had one that lasted 10 years mounted on the stern rail on our Beneteau
331 and bought a new one when we bought our B393 3 yrs. ago. Seems like I caught it on sale
at West Marine
for about $125.
We now have a permanent propane line running from a 10 lb. tank in the propane locker.
I suspect I would look at other options if I had a Cat...
