From Eric Bogle's "Safe in the Harbour":

"Ah to throw off the shackles and fly with the seabirds
To where green waves tumble, before driving sea winds.
Or to lie on the decking on a warm summers evening
And watch the red sun fall burning beneath the earth's rim"

Brings back lots of memories of passages long gone. My interest in "watching the red sun" falling burning beneath the earth's rim in those days was to check the ship's gyro. You took a bearing of the setting sun with the sun one half it's size above the horizon, funny thing was, whoever took that sight always stayed to see the sun fully down.
