I was just checking marine forecasts, it could be a little sporty of of the Jersey coast on Saturday, with seas in the 3-5 range.
It was 5 ft all week, with 20 kt East winds and 8 sec periods between swells. That means it's probably going to be dark, murky and low viz down at 80 feet.
We were supposed to go tomorrow (9/12) but called it off. Nobody wanted to waste our time feeling our way across a dark bottom. It should settle down by Sunday, as long as the wind slows down and the swells die off, which is in the forecast. Still, I wouldn't expect stellar visibility, and I definitely wouldn't go without a wreck reel and light.
When using your wreck reel tie off as close as possible to the anchor line. When you get back to your tie in point, you want to be at the anchor, not looking for it.
In really rough seas where the anchor is likely to come loose (especially on wooden wrecks), I've seen divers tie onto the anchor itself. We frequently do that on "rock piles" which don't have good tie in points. Generally frowned upon, but if the viz is bad and the anchor's a rockin, it does you no good to be tied on NEAR the anchor, have it pull loose, and then you get back to it and it's not there. The worst that can happen is the anchor pulls loose and all the divers tied into it get pulled, sometimes with lines tangling. Certainly not optimum, but beats a free ascent in bouncing seas followed by a 300 yard surface swim.
If lines get tangled up, treat the other diver's lines the way you'd want to be treated. Usually, it's caused by crossing over someone's line and they come over yours, only they're 100 ft away and don't realize it. If there's ten divers on a single wreck, there's no way you can avoid lines crossing. Just be smart, alert, respectful. I've been tangled so bad at the anchor that I cut my line (NEVER cut someone else's) and got my stainless steel clip back when the anchor was brought to the surface. You don't need your reel for the ascent if you're already on the ascent line.
My reel tangles occasionally. If it's the end of the dive, I just wrap the line around it, throw it in my game bag and deal with it on the surface. Mid dive, I can disassemble and untangle at depth, but that eats dive time.
My main flashlight is duct-taped to the top of my wreck reel. That way, when I swim, the line spools out while my flashlight scans the reef or wreck for holes where I can find lobsters. But my other hand is free. Also, I can wind in the line and still have the flashlight working for me.
Some folks mentioned practicing deploying your safety sausage. You must discuss that with the captain first . On many boats, when the crew sees a safety sausage, they're going in to see what the problem is.
