A fleet
Navies and large International Shipping companies have fleets.
Naval fleets are subdivided into squadrons. Depending on the size
of a given Navy, a squadron of large ships, could comprise
of 4 to 6 vessels. Squadrons of Patrol Vessels or Submarines could
be larger.
U-boats, packs of German U-boats searching for American ships were called wolf packs
The name for a group of ships, beginning with an "s", would be squadron.
As far as I am quite sure, there were definitely ships... and paddle boats.
