This is from the novel Tales of War, about German Navy at the time of Great War.
There was he, who should have been breasting the blue, or at any rate doing something salty and nautical, far out in the storms of that sea that the Germans call an Ocean, with the hurricane raging angrily in his whiskers and now and then wafting tufts of them aloft to white the halyards; there was he constrained to a command the duties of which however nobly he did them could be equally.
I do not understand the meaning of part in bold:
and now and then wafting tufts of them aloft to white the halyards;
Is that wafting tufts of whiskers? What does "aloft to white the halyards" mean?
I am glad if some one kindly give me some advice.
