syntax & semantics really dont matter all too much, I just think there's room to distill your lines more concisely
based on my limited perception

I don't think the concept itself requires revision.
Just watch out when forcing a narrative to support the main idea
I think good poetry reflects on itself in a subtle way
as though lines can only grasp at the idea but can't directly define its parameters.

No one will save you.  Follow your instincts, the opener is too explicit, though I understand its function here
as the water rises, covers the shore.
rising waters cover the shoreline
Homes and less sturdy crafts, as their hope sinks,
hope sinks along with homes and less sturdy crafts
break in the ocean's unforgiving roar. nice. consider 'crash' in place of 'break', just preference
Know, a sound mind will cut the turbulence,
and stay afloat, drifting above the waves,
sweeping waves carve
maintaining the course set by circumstance,
at the mercy of each swing
seeking a future only courage paves.
absent of courage,
Noa needs confuse the company kept,
but rife with faith
when rationed food would vanish in the night.
What could be done, as you, the captain, slept;
and images of land passed out of sight
No wonder, when you got there, you got drunk.
                       upon arrival, drunk in vain
No wonder you wish you had stayed,  and sunk.
 corporal state disdain, you should have been the one blah blah
