Doesn't have anything to do with being on a boat.

Water needs some little bit of something for the water vapor bubbles to
form on. If the water is really clean, and the cup too, you can heat water
to a couple of degrees over 212F because there are no little bits. Then
when you add the coffee, it boils a little. Solutions:

Spinkle a couple of particles of instant in the water before you heat it.

Don't heat it quite so much.

Don't use instant coffee. ;-)

Don't wash the mug. ;-)

(Actually, it's a Republican plot, Harry ;-) ;-)

Sometimes when using the microwave on the boat to boil water, the water
turns 'nukular.'

That is, when I take the coffee cup out of the microwave, and spoon some
instant coffee into it, the water "boils up" and overflows the cup.

This occurs maybe one time out of 20, but when it does, it makes a mess.
I typically fill the cup to the same level with jug water (no one should
drink water stored in a boat's water tanks!), use the two minute setting
on the microwave to boil it, and put in the same super teaspoon amount
of coffee.

What's going on here?
