Thank you both. FINALLY some numbers that are really helpful. ^^

Everyone is like "get 145 surveillance for that stupid otter" when asking what surveillance you need for various rare items. So I take days to gather stuff and then hours to craft everything only to get a ship that can get like extremely high surveillance but doesn't have enough range to get to Sunken Vault because that damn otter only needs like 40 or whatever. And if it gets enough range then favor is too low. Whatever. More crafting then. It's just so annoying that everyone seems only to think in otters and kamacite when it comes to submersibles.

I'll just have to make all parts except for Syldra parts and hope I can get enough. Currently I have all Shark and Unkiu parts, 3 Coelacanth (no stern), 2 whale (bow and that usless hull I made for leveling faster). I need so much more Darksteel Ore again...
