Speed increment +(1, 2, 3) means the speed of the ship will increase to Fast, Fast+, and Fastest respectively, assuming the base speed is slow.

Required boiler is...well, how many and what kind of boiler you need to give the ship within a speed group, to get listed speed.

....or that's how I think.

Seriously it's easier to read the table above it, despite it being cluttered with words.
