In open sea conditions, it's very difficult to guard against such events, but they are also quite rare. Obviously someone sailing across an ocean is doing a lot of night sailing which makes things worse in that regard too.
Around our area such debris is the norm rather than the exception. Plenty of rivers and creeks coupled with logging and boom towing operations can leave some impressive amounts of floating debris - from small branches to full sized logs. The worst are the "deadheads", half sunken logs that are floating vertically just at the surface (or below).. have seen them as large as 3-4 feet across - hitting one of those square on is going to do damage to anything. We do keep a sharp eye, and I feel for the high speed powerboater who has to try to spot these things as they zoom along at 25-35 knots. Lots of boatyards get summer work replacing shafts and props and struts as a result.
Lots of the 'survival at sea' stories got started by the vessel hitting some large object at sea.. whales, containers, who knows....
