What's left of the pier would never be structurally strong enough for either. The "make-safe" operation of a couple of years back has simply left the bare bones (to rot IMO).
The original berthing structure at the "dog-leg" at the end was a massive timber construction, it was still sound (as far as I know) when it was demolished in the early nineties. Rumour had it that its removal was to hasten the demise of the rest of the pier. As was the removal of the stone buttress at the south-east corner of the ironwork.
That what's left of the pier is still standing after the neglect and deliberate abuse is testament to the Victorian engineers who designed and built it.
