If the line isn't otherwise being used, it couldn't hurt, provided car is taken that it doesn't tangle in the sea anchor line. The line itself is stored inside a lightweight clear plastic sheath. On the Navigator the line and quoit is secured with a rubber band to the interior grab line to the left of the entry in the corner of the raft. I found that having to take the sheath off the line was a bother and impacted the time it took to get ready to throw the line. The twisted poly is relatively stiff, not as flexible as other lines we've tested, and was not as easy to re-coil for a second throw.
Poly line floats, making it easier to grasp or see in the water.
The wood handle is wrapped with non-slip black covering and there are black end caps where the line attaches. The line and handle is secured with Velcro to the raft by the entry or on the left of the entry next to the canopy arch. Small strips of Velcro keep the line neat. If the Velcro was tabbed, as are other Velcro keepers on the raft, it would make it easier and quicker to deploy the heaving line. The coiled line falls readily to hand and doesn't tangle easily.
