</>What does Unsinkable (Hull of Steel) do?

The Stormstrider is a lovely little boat with one flaw: everything in the sea wants to put a hole in it. Unsinkable removes that particular worry. Flip it on and the hull simply stops losing health, no matter what crashes into you. This is the mod for learning a new stretch of the map, for pushing into the harder tiers without a two-hour reset, and for co-op nights where one of you is very good at this game and the other is very much still reading the buttons. You still steer, still load, still swing at the things climbing aboard - you just stop losing the boat over it. There is a Patch The Hull button too, for when you would rather keep the danger and simply undo one nasty moment. Press it and you are back to full. Pairs nicely with Bottomless Barrel if you want a run where nothing can stop you at all.

</>What is Unsinkable (Hull of Steel)?

Looking for a way to stop sinking in Ship of Fools? Unsinkable keeps the Stormstrider's hull at full strength no matter what the sea throws at it, so a missed block or a badly timed wave no longer ends a run you have spent an hour building. There is also a Patch The Hull button for players who want to keep the tension and simply undo one disaster. It is popular for learning unfamiliar sectors, for scouting the harder difficulty tiers, and for co-op sessions where the two players are at very different skill levels.

</>Common questions about Unsinkable (Hull of Steel)

What does Unsinkable do in Ship of Fools?

Unsinkable stops the Stormstrider's hull losing health in Ship of Fools, no matter what crashes into it. Waves, harpoons, the things that climb aboard and start chewing on the boards, none of it takes the boat down while the toggle is on. Everything else about the run is untouched: you still steer, still load and fire, still patch the breaches if you want to, and still swing at whatever comes over the rail. What goes away is losing an hour-long voyage to one badly timed wave. There is also a Patch The Hull button for players who would rather keep the danger and just undo a single disaster.

What does the Patch The Hull button do?

Patch The Hull repairs the Stormstrider back to full the moment you press it, and it works whether or not the main Unsinkable toggle is on. It exists for a specific kind of player: someone who wants Ship of Fools to stay genuinely dangerous, but does not want a single bad thirty seconds to end a voyage they have spent an hour building. Leave the toggle off, sail the run properly, and press the button on the rare occasion something goes catastrophically wrong. Used that way it acts more like a safety net than an invincibility switch, and the tension of the run survives intact. Press it as many times as you need.

Does Unsinkable protect me and my crewmate, or just the ship?

Just the ship. Unsinkable covers the Stormstrider's hull, which is the thing that actually ends a run in Ship of Fools, but you and your crewmate are still ordinary people standing on a boat. Anything that comes aboard can still knock you about, and you still need to deal with boarders rather than ignoring them. That is the right scope for the mod, because a hull that cannot sink already removes the run-ending failure while leaving the moment-to-moment fights meaningful. If you want the deck itself to feel safer, the answer is mobility rather than armour: Deck Sprinter to get out of trouble faster, or Second Wind so you always have a dodge available.

Does Unsinkable stay on if I switch to a different ship mid-run?

Yes. Swapping to a different ship in Ship of Fools replaces the boat you were sailing, and a protection applied to the old one would quietly stop meaning anything, so you would sail on believing you were safe until something put a hole in you. Unsinkable keeps checking, so the new ship is covered from the moment you are aboard it, without you needing to toggle anything off and on. The same goes for a fresh sector loading in. It is the sort of gap you only find out about at the worst possible moment, which is exactly why it is handled rather than left to chance.

Who is Unsinkable for?

Three sorts of player, mostly. People learning a stretch of the archipelago they have not sailed before, who would rather see what is coming than reset an hour of progress. People pushing into the harder tiers, where scouting what the game throws at you is half the battle and dying to it repeatedly is not the fun half. And co-op crews with a big skill gap, where one of you knows Ship of Fools inside out and the other is still working out which button swings the oar. In that last case Unsinkable is what lets you actually play together instead of one person quietly carrying the whole voyage.
