Here's some advice:
If you have a gas motor, and . . .
you are using it to dock in a crowded marina because the wind died, and . . .
you have taken down your sails and neatly furled them for storage, and . . .
you are already in the narrow passage between docks, and . . .
the wind has magically reappeared, but blowing sideways, and . . .
your paddle is safely locked inside the triple-latched watertight cabin hatch . . .
do not run out of gas.
Do. Not. Run. Out. Of. Gas.
