One other thing is that you can take a spare sail or a sail bag and lash it to the outside of the hull covering the hole. This will slow the water down and give you time to come up with a better solution in plugging that hole.
The sail does have cringles which you can use to lash the sail tightly to the hull and thus slowing the ingress of water. Then your pumps may be able to keep up with that influx of H2O. And now with the influx reduced you can come up with a patching solution for that probmatic hole in the hull.
