Beat-offbeat scansion of "The Pilot"

As an example, look at the following. You may wonder about my virtual offbeats, well I was trying to figure out the metrical pattern. This is a tetrameter poem, with a lot of feminine endings.

I typeset this with the HTML pre / pre tags. I hope all the lines are there, this web-based editor is a little jumpy. Note that the symbols come under the vowels.

Here is my beat-offbeat scansion of

The Pilot

From the Past and Unavailing
 B    o  B   o   b o B  o
After groping, after fearing,
B  o    B o    B  o   B  o
Into starlight we come trailing,
B  o   B  o     b  O     B  o
And we find the stars are true.
b    o  B     o   B   o     B
Still, O comrade, what of you?
 B    o  B  o      B  o   B
You are gone, but we are sailing,
B  o    B     o   B o    B  o
And the old ways are all new.
b     o B[o] B   -o-      B
b     o B    o   b   O    B

For the Lost and Unreturning
b    o  B   o   B  o B  o
We have drifted, we have waited;
B  o     B  o    B  o    B  o
Uncommanded and unrated,
b  o  B  o  b   o  B o
We have tossed and wandered, yearning
b  o    B     o    B  o      B   o
For a charm that comes no more
b  o   B     o   B     o  B [o]
From the old lights by the shore:
 b    o B *  B     -o-      B [o]
 b    o b    O     b    o   B
We have shamed ourselves in learning
b  o     B    o   B     o   B   o
What you knew so long before.
 b   o    B   o  B    o B

For the Breed of the Far-going
b    o   B   -o-     B * Bo
Who are strangers, and all brothers,
 B o      B  o    B   o     B  o
May forget no more than others
B   o  B   o  B     o  B  o
Who looked seaward with eyes flowing.
 B  o      B  o    b   o     B  o
But are brothers to bewail
B  o     B  o    b  o B
One who fought so foul a gale?
B     o  B      o  B   o  B
You have won beyond our knowing,
 B   o    B   o B   o     B o
You are gone, but yet we sail.
 B  o    B     o   B   o  B
