Having only been down 20 or so years, the Segontium is amazingly intact. The funnel stands upright from the superstructure with a pair of ventilators right behind it. I had quite good visibility, but should you be less fortunate this provides an easy clue as to which way is forward and which side is which.
Dropping to deck level at 26 metres on the port side, the railing is intact and draped with several layers of trawl net. Staying clear of the netting and heading aft, at the stern the otherwise clear deck is broken by a forest of ventilators of different shapes and sizes. On a smaller scale they could easily be used as a desk tidy. Everything is smothered in anemones, even the deck.
Between the rudder an the hull, the propeller is shrouded in a heavy steel guard with more trawl net pulled tight under it. It is somewhat ironic that a guard designed to keep nets and ropes clear of the propeller when the Segontium was working has now trapped another fishing vessel's nets.
Behind the funnel and ventilator stacks the engine room ventilation hatches are open, though on a ship this size they are far too small to swim through. Nevertheless, shining a strong light inside may reveal a glimpse of the engine.
By the port railing a grating above the deck marks the point where a lifeboat would have been stored. The railing here has a gap that looks intentional rather than damage subsequent to sinking.
Forward of the funnel an open doorway marks a shaft and ladder down to the engine room. Again very tight for a diver, all but the most suicidal of hole fiends will again have to be content with shining a torch down to see what bits of machinery they can glimpse.
The aft part of the wheelhouse is steel, but the forward part must have been wooden because it has rotted completely away making it easy to swim around what would have been the inside. To either side of the wheelhouse steps lead down to the main deck at 28 metres.
On the main deck the hold covers have partly caved in to give a shallow valley along the centre of the deck. Almost immediately a pair of square hold hatches provide a view into the hold and a way in for those so inclined.
Next on the starboard side comes a small hoist. There is no corresponding hoist on the port side; like most fishing vessels the Segontium would have been set up to work over only one side of the ship.
Further forward a square frame stands from the deck, followed by a small winch and another hatchway down to the hold below, again showing the one-side working of the ship.
The mast has a pair of beams angled against it, originally used to lay the muscle dredging equipment over the side, though the dredging equipment was removed from the Segontium before it left on its final journey to the scrap yard.
Steps lead up to the bow deck, the port side again obstructed by nets and the starboard side clear. It is a small bow deck with barley enough room for the anchor winch.
On the starboard bow close to the seabed there is a dinner plate sized hole partly obscured by enormous plumose anemones. Rounding the bow, on the ports side and slightly higher there is a considerable dent. Could the Segontium have hit something on its final voyage? Or could this have been old damage, or maybe caused by one of the many trawlers that seem to have lost their nets on this wreck?
