I'm damned if I know what to say, my friend,
for I have never given as you gave.
So difficult for me to comprehend,
I have dabbled while you have tidal-waved.

I've buoyed and broached* but not to your extent -
my shallow sailing's hopelessly tepid.
My comfort although worthless is well meant -
It grieves me to believe you might be wretched.

Your shipwrecked heart has strangely scuttled mine,
it fears you sigh for siren song again.
Beware, my friend, they're cranky* not benign
I swear you'll pay in ways not yet ordained.

Let go of that cruel Circe whom you've clasped
those gorgeous tresses harbour deadly asps.

Broach - When a sailing vessel loses control of its motion and is forced into a sudden sharp turn, often heeling heavily and in smaller vessels sometimes leading to a capsize.

Cranky - Possibly from the Dutch krengd, a crank was an unstable sailing vessel. Due to a faulty design, the imbalance of her cargo, or a lack of ballast, a crank would heel too far to the wind.
