S.C. Code § 29-9-80
When there is money due to more than one person holding a lien upon a ship or vessel under the provisions of this chapter all persons interested having been cited to appear and answer, the claims of all shall be marshalled and the court shall make such order or decree as may be necessary to prevent the enforcement of a double lien for the same labor, materials, stores, provisions or other articles and to secure the just rights of all. And the proceeds arising from the sale of such ship or vessel, after deducting all proper costs and expenses, shall be distributed among the several claimants to the amount of their respective debts. When such proceeds are insufficient to satisfy the liens of all those having liens for labor they shall receive a percentage on their respective claims one third greater, as near as may be, than those having liens for materials, stores or other articles.
