I've seen plenty of floats around the approaches to Welcome Pass near Secret. At its narrowest, the Pass is only 400 m across, throw in wind and current and a tug with a boom in tow has to be very precise setting up for the transit. Not hard to see why some floats are snagged by the boom. And sometimes you see one that's inside the RCA boundaries anyway, no sympathy there.
I'm still figuring out how to be a consistently successful trap fisherman, but I have managed to avoid putting traps in the way of tugs or commercial crabbers and prawners.
