Options? No diversion, so options are ditch or land - I know which one I'm going to have a blo**y good go at achieving. Usually even if the deck is way out of limits there are a few tricks - getting the ship to run down sea usually quietens deck movement, although the wind can then be an issue. If you have the fuel to sit alongside the deck, ready to leap onboard as soon as a short quiet period comes along, then happy days, that's the plan!
