The order to "splice the mainbrace" (i.e. take rum) can be given by the Queen as commander-in-chief, as occurred on 29 June 2010, when she gave the order to the Royal Canadian Navy as part of the celebration of their 100th anniversary.
女王作为总司令可以给出“splice the mainbrace”的命令，就像2010年6月29日的那样，为了庆祝海军成立100周年，他们向加拿大皇家海军下达了这个命令。
