I wouldn’t worry about planning to winch a bull out of whatever situation they are in. I guess for road hunters that’s a Good plan but if you kill a bull in water as un likely as that probably is. Just cut it up skin on, you can trim off a 1/4 of whatever meat touches dirty stuff. But you should be able to gut and cut an elk in half and drag it out of a marsh also. If that situation comes up you will figure it out.
Just don’t get scared and leave it whole over night thinking you need to have more people to not waste meat.
