The golden rule on a small boat is that you never bring anything onboard that cannot do two jobs. Coffee is an essential for me. I am talking about real coffee, instant doesn’t cut it. How instant coffee survives on the market is an entirely different conversation. Instant coffee is not on my boat and never will be.
I have gone through a number of brewing methods. A friend of mine has an electric perculater, circa 1950. To me it always looks a little electrically unsafe and does seem to overload the breaker on the shore power on far too many occasions. The newer electric perculators all seemed too big for my needs. A stove top model meant giving up a burner on the stove. Since I had no stove, that was an easy choice not to make.
