No, there are no lines attached (to minimise the risk of entanglement). In good visibility with pre-laid lines, you'll often not touch the line.In poor visibility you'll gently hold the line. If there isn't a pre-laid line, the lead diver will have a reel which they progressively release, and tie-off at intervals (to any useful protrusion).
