When Swordfish could fly from seaplane carriers

Could Swordfish actually take off and operate from seaplane carriers?

Yes in the 1930s and early war, especially from the water, but increasing weight and worn airframes made the operation progressively harder.

Float-equipped Swordfish could take off under their own power from the water, and seaplane carriers supported such operations before the war. They did not need to launch a torpedo-armed aircraft directly from a catapult to make the concept useful. As wartime equipment increased aircraft weight and airframes aged, the margins narrowed and the practice became less attractive. This distinguishes an early feasible capability from a later routine one.
