Anchoring

No anchor was actually dropped. In stead, Stewart jumped in the water, fully geared up for action, to go and tie down the M/V Trident directly to the wreck.

Depending on the conditions, one or two crew divers jump in the water near the drop line's buoy and are handed the end of a ticker line, after which they descend into the blue looking for the wreck.


If they're lucky they'll be able to see it on their way down, or find it thanks to the fish that usually hang around a wreck's vicinity, using it as shelter. If the visibility is bad they might need to perform a circular search using a reel attached to the drop line. If unlucky they may have to resurface and the whole procedure then needs to be repeated from scratch for another try.

Usually though, as was the case this morning, they find the wreck on the first try, tie off the line, give three strong thugs to signal the surface crew of the successful tie off and either resurface immediately or after performing a short dive. At this point the M/V Trident is securely tied to the wreck, thus ensuring a direct line of descent & ascent for subsequent dives. No need for divers to search for the wreck each time they go down, loosing precious time and running the risk of not finding it in bad viz.

Stewart having done the tie-off, Michael then jumped in to set up the deco rig, a horizontal metal bar hanging 6m below the ship, where divers can perform their last deco stops, breathing surface supplied oxygen.
