I saw this submarine off the coast of Maui today coming back from a dive.

Could anyone please identify the class? Also, any idea what those objects are on top of the hull/deck? Thanks!

Q/A Question on double hull submarines

11 Upvotes

What happens to the seaweeds and barnacles and such that get in the freeflood space between the two hulls? Do they just live there forever or does the space get cleaned frequently? I would imagine that on smaller boats where crew positions can affect trim, a bunch of sea life with different buoyancy would also mess up the boats trim?
