Answer:
I help boats park
In my life I must bare my bloodline I must share.
I run smoother than any rhyme, I love to fall but cannot climb. What am I?
I am always in front of you, but you will never see me. What am I?
I move without wings Between silken string I leave as you find My substance behind.
I fly to any foreign parts assisted by my spreading wings. My body holds an hundred hearts Nay I will tell you stranger things when I am not in haste I ride and then I mend my pace anon.
