Расставьте знаки препинания, объясните их постановку.

Красиво смотреть со стороны на судно окрыленное белыми парусами грациозно плывущее по бесконечной глади морских волн. Но взгляните на число рук приводящих его в движение! Парусное судно обмотавшееся веревками и завесившееся парусами дремлющее в штиль и лавирующее при противном ветре не может в одно мгновение двинуться назад или быстро поворотиться.

"I've been expecting you".
