People I’ve seen in the 20-odd years I’ve been white-baiting, don’t wear full-length waders (with the shoulder straps) but wear cut down gumboots from the freezing works.
Once these fill up with water, you are pretty much stuck where you are.
I pulled a 76 y/o guy out of the surf at the Orari mouth in 1988 and I am by no means a strong swimmer.
Let’s put it this way, you are using a net that gives resistance to the water, you are turning that into the current, it is only a matter of time before the sea is going to have it’s way with you.
You’d better be ready when it does.
If you can’t white-bait, stick to a rod.
