I have never been in that very lucky situation, yet.....But I am afraid, by my calculations, it won't matter whether it is a kingfish or a nuclear submarine.....In the end, somethings gotta give. Either your stuff breaks, you let go, or you hang on so tight, you sink, or get pulled out of the yak, go water skiing or whatever. The rules are if nothing breaks, you stay connected and go with it. For practical purposes, if your rod is kept pointing forwards, you will find it hard to capsize, and you should follow more easily in case the submarine/fish tires.
I hope this helps
Cheers Andybear :lol:
Edit: Very good idea to have the rod pointing forwards for another reason.... if the line does break, you have less chance of doing a backward somersault over the opposite side and into the drink...
