Why not divide the Grand Fleet around the headland?

Why not split the British force to conduct several operations around the Baltic approaches?

Britain's decisive advantage is a concentrated fleet, and dividing it would let the entire High Seas Fleet defeat isolated groups in detail.

The Grand Fleet knows that Germany must eventually respond with its main force. If British ships disperse among several coastal tasks, any one group may meet the concentrated High Seas Fleet before support arrives. Tactical variety would sacrifice the numerical advantage on which the operation depends. Jellicoe's safest choice is to keep the fleet as a single fist until the German battle fleet is neutralized. Local operations can follow once the decisive threat has been removed. That concentration is the prerequisite for every smaller blockade and landing objective.
