Depends on the water though?
Near Scandinavia there is a place where wooden ships are extremly well preserved while under water.
Cant really find it in the article but there are no bacteria/animals that destroy the wood.

In the Baltic sea, due to low salt, there are no ship worms.

The seas probably lack oxygen there which means no bacteria/animals could live there. Quick Google, Wikipedia tells me the Baltic sea is indeed quite a dead sea.
Interestingly enough this is also the cause of coal/gas/oil in our ground. Without an anoxic environment carbon waste decays and does not transform into our carbon deposits which we use for energy nowadays. Thus big carbon deposits in the ground point to anoxic environments in the past.

I thought the vast majority of coal was formed from trees that fell before there was anything that could break down the lignin in their cells?

True, I thought that was the case as well but that hypothesis is being challenged recently. Both ideas are also not mutually exclusive. In swamps around the world you can still see the preservation of carbon life forms.

Its the Vasa, a Swedish warship from 1626. The ship sunk after sailing 1300 meter.
