Not sure why you'd dive the St Lawrence with no gloves, those zebra mussels are like razors.
The buoy for the Lillie wreck is upstream, and the mooring block is even further upstream. Pulling yourself down that line is a wee bit of effort. Often fishing lures get caught on mooring lines, I like Kevlar palm gloves.
The guide rope from the mooring block to the wreck goes downstream so not sure why you'd pull along it as you're already going with the current at that point.
Standard instructions I've heard to dive this wreck from boat captains are jump in, float on the surface over to Sparrow island shallows, adjust gear as necessary, get negative and pull and glide down the rocks to the wreck and the chain that goes along the side of the wreck.
It's not too challenging when done this way. You avoid working down the mooring line and walking across the bottom in 50ft. And using all that gas.
*Edit* who taught him to clear a mask that way, looking down? And at 6 minutes the SPG hose leaks.
Having done this dive numerous times....and these days with redundant tanks and Kevlar gloves....I remember the first time I did the dive, and how a kind and experienced diver told me to grab a rock to stop a descent if the current took me down, it would have helped those divers so much if they'd had gloves. And other skills.
