A thermos flask is very handy but it does not take the place of a
stove on a small cruising vessel.

A daysailor needs a stove?


Some do.

If it's a "daysailor" that is likely to be sailed for long hours, in
chilly weather, and/or for more hours and/or with more crew than a
Thermos is likely to take care of.

Please note I said "small cruising vessel."

One factor to bear in mind is that you can warm up the cabin/cuddy
with a small stove, and warm up your hands with it... not something
you can do with a Thermos.... especially an empty one....
