Engadine was one of two seaplane carriers assigned to operate with the Grand Fleet and Battle Cruiser Fleet (she operated with the BCF at the time). The other was the Campania, a converted ocean liner, which was based at Scapa Flow with the main battlefleet at the time of Jutland. Campania had missed the signal to sail to Jutland, as she had been moored in a separate part of the harbour from the rest of the fleet. She set off about two hours later, but was commanded to return to Scapa as she would be passing, unescorted, through U-boat infested waters.
Two other seaplane carriers, Vindex and Riviera, operated with Harwich Force, which did not sortie at Jutland. The rest of the British seaplane carriers were in the Mediterranean. There, Ark Royal (the only aircraft carrier built with a sail) was operating as a base-ship at Imbros, while Ben-my-Chree, Empress, and two converted German merchants operated against Ottoman forces in the Eastern Mediterranean and Red Sea. The air wing of Ben-my-Chree probably had more experience with torpedo bombing than anyone else in the world, and its certainly interesting to imagine how they'd fare at Jutland. The main torpedo-carrying seaplane used, the Shorts Type 184, struggled in the hot conditions of the Mediterranean but managed to score a few torpedo hits when operating from Ben-my-Chree - Engadine was operating the Type 184 at Jutland, but I don't believe she carried any torpedoes, and her air wing had little experience with them. Still, none of these ships had enough aircraft, even put together, to score more than one or two hits on the High Seas Fleet. Still, a single torpedo hit was enough to make things tricky for most WWI-era battleships, and would likely have been very bad for a pre-dreadnought.
