This sounds fun....
CHALLENGE MODE!Your hallowed ship carved from the motherbeard granite of the mountainholm herself has struck catastrophe!/Iceberg!/Leviathan!
Luckily, 7 survivors managed to not drown due to being fat enough to float, because armok knows no-one is going to give them swimming skills. The island seems to consist of: Tropical jungle / Wild desert / Tundra or Glacier.
Broker/Ship captain. Negotiation and intimidation. Say hi to other ship captains and keep that crew in line!
Ship Carpenter/Engineer, and possibly some skill in clothmaking so he could fix the ropes.
Ship Doctor. He's probably a hack.
Ship Cook/brewer. I can see this guy cooking up some grog. Probably the reason your dwarves are so weak and flimsy: Scurvy.
Burly, Fightin' fisherdorfs. Fishing is real hard, folks. Think anchor and mom tattoos. Fishing labors, wrestling, fighter and dodger if you so choose.
Dogs can swim and have been known to get on floatsam shipwreckage, so roll a dice or something and see how many safely made it to shore. Anything larger would probably drown and if you're lucky wash up on beach, so you can slaughter your wagon animals to replicate that.
Doggies on a roll of:
1 - No survivors
2/3 -
Mister Snuggles.4 - One doggie.
5 - One female, but she carried her puppies to shore!
whosagooddoggieyesyouare!
6 - Breeding pair.
I'd also like to think that such a ship would be carrying chickens for a long voyage, but it's much more likely that a few ducks/drakes would be able to make it to shore.
Items:
Booze and food barrels.
Plenty of wood, any wooden items.
One metal weapon. Copper Hammer or iron Axe. I'm sure the carpenter would have the sense to grab something useful and not drown on the way out, but I just don't see him managing to make it out with a spear.
Rope, cloth, clothes, bags. They'd all wash up pretty easily.
No Picks.Easy Mode: One salvaged anchor (anvil. the rope attached to it was caught and it was dragged in. 30 extra rope.)
