^crew” in other statutes having other purposes. This Act, as we have seen, was to provide compensation for a class of employees at work on a vessel in navigable waters who, although they might be classed as seamen (International Stevedoring Co. v. Haverty, supra), were still regarded as distinct from members of a “crew.” They were persons serving on vessels, to be sure, but their service was that .of laborers, of the sort performed by longshoremen and harbor workers and thus distinguished from those employees on the vessel who are naturally and primarily on board to aid in her navigation. See De Wald v. Baltimore & Ohio R. Co., 71 F. 2d 810; Diomede v. Lowe, 87 F. 2d 296; Moore Dry Dock Co. v. Pillsbury, 100 F. 2d 245.
Regarding the word “crew” in this statute as referring to the latter class, we think there was evidence to support the finding of the deputy commissioner. The fact that the certificate of inspection called for three “deckhands” and that the captain included the decedent to make up that complement is not controlling. The question concerns his actual duties. These duties, as the Court of Appeals said, did not pertain to navigation, aside from the incidental task of throwing the ship’s rope or making the boat fast, a service of the sort which could readily be performed or aided by a harbor worker. What the court considered as supporting the finding of the deputy commissioner was that the primary duty of the decedent was to facilitate the flow of coal to the vessel being fueled, that he had no duties while the boat was in' motion, that he slept at home and boarded off ship and was called each day as he was wanted and was paid an hourly wage. Workers of that- sort on harbor craft may appropriately be regarded as “in the position of longshoremen or o tier casual workers on the water.” Scheffler v. Moran Towing Co., 68 F. 2d 11, 12. Even if it could be said that the evidence permitted .conflicting inferences, we think hat
