Analysis of Pod of big ones moaning

Out now 2 hours
Settled in course
Between coast and
Three islands
only marginal wind.
Sam rubs his eyes
From all the watching
For humpback.

Suddenly a grey hillock
Emerges from the brine.
One large eye checking
Us out with benevolence.
Wake jumping ship
From his rear end
Sam going nuts now.
I lock in our speed.

Then a second, third and fourth.
Spume going everywhere.
Communal moanings
Transfixed.
But not those holy sounds
As when deep down.
And Leviathan meets his God.
