Two centuries is enough for nearly all electrical things to fail, and spare parts can't be made without an industrial base.
*Some* places might have basic radio; batteries aren't hard to make (2 metals, some acid); water and wind power are fairly easy to gather with magnets and wire.
A ship engine requires infrastructure. Especially to fuel it. (At *least* a coal mine; refining is more.) Anywhere there's decent regular winds wouldn't bother with more than sails.
(All IMHO.
