From my scuba diving experiences around the Scillies I would think that not a lot would still exist dependant on tides and currents in the area.

Large timbers and maybe some of the planking from one side of the hull could still be there though.

Excuse the rough sketches but this is how I`ve had it explained to me on wreck dives on the remains of the HMS Association that wrecked off the Scillies.

Pic 1:

If the wreck settles on its keel on the seabed then the hull will roll onto which ever side the sea currents force it or the centre of gravity takes it.

Pic 2:

Once on its side the decks will be the first to go due to them being flat against the force of the currents.

Pic 3:

When the decks are gone, one of two things can happen.

1 - The upper side of the hull collapses down onto the lower half

2 - The upper side of the hull gets blown away in the direction of the current and disintegrates over time

Pic 4:

The remaining side of the hull now almost flat to the seabed gets covered by sand and the like and disappears just under the surface of the seabed.
