With that much weight onboard you would have have really needed to figure out moving weight around, and then backwind the main until the boat is well around. Without the jib the boat is really going to have a lot of weather helm and really want to round up.. So you are going to need to be well out of irons before trying to sheet it in. Also the loss of you jib Halyard would have caused the mast to fall further aft... further adding to the weather helm problem.... using the jib sheet connected to the chain plate at the bridle you could have put a bit more rig tension on to make you life a little easier.
Heck with that many people onboard I would have capsized, went for a summer afternoon swim, then pointed the boat in the right direction, and then right it long before I would have spent 30 minutes in irons..
With the boat on its side in the water you could have fixed the jib halyard while the kids played.
You can have lots of fun on a H16 sans jib in the right conditions..
