This theory was based on the assumption that Great Britain would have to send its fleet into the North Sea to blockade the German ports (blockading Germany was the only way the Royal Navy could seriously harm Germany), where the German Navy could force a battle.
Međutim, ova teorija je bazirana na pretpostavci da bi Velika Britanija morala poslati svoju flotu u Sjeverno more da bi blokirala njemačke luke (blokada njemačkih luka je bila jedini način na koji bi Kraljevska mornarica mogla ozbiljno nauditi Njemačkoj) čime bi njemačku mornaricu prisilila na bitku.
