Long lines, yes. "Streaming warps." They're to be rigged as a "U".
Any drogue can also be streamed, made of canvas or anything to produce drag, intended to slow the boat and keep it stern to wind and discourage broaching (turning sideways to the wind). However, under gale conditions nothing has much effect, as it tends to skip on the surface. That was the trouble with the patent drogues, which broke or fouled. The Jordan series drogue, a "series" of more than 100 small individual cones, seems to do the best job. The forces on a successful drogue are so great that standard stern cleats are not considered strong enough, and stainless plates on the hull counter are recommended.
A parachute sea anchor designed to stream from the bow (and to stop the boat, rather than slow it) should not be streamed aft.
