Hi Vance,
The KSS/Eurosub is very,
very stable in roll; you can stand with 3 persons on deck. For construction simplicity
the tanks are divided in a port and starboard tank and have a common vent of 1 “
at the bow. Boat dives as planned a little stern heavy.
The only thing is that a
person cannot stand far aft on deck but I believe that is also not
possible on a K boat.
We don’t have the
problem that one tank is blown dry and the other not. I your case , I think the
boat should be level.
Al the Best, Emile van Essen

Alex and Dan H and whoever,
I am redesigning MBTs for my 1-man K
along the lines of Carsten & Emile's
KSS. Has anyone done stability games with their K-boat with one ballast tank
vented and one blown dry. I'm trying to get an idea of the angles involved when
flooding the new tanks. At present, they are coming out to about 8' long
overall from front to back and are plumbed for port and starboard, rather than
fore and aft. The bottom vents would be about 2/3s of the way back along their
calculated length with the vents right up in front (larger ball valves than you
guys are using, so there will be less hang time involved on the surface). My
alternative is to divide each tank at the midpoint (under the conning tower
side ports) and plumb the aft sections together through a 1" T and then to
the vent valves, and the forward one pretty much as the Captain called for. The
issue with that is those aft tanks staying level from side to side as the boat
rolls in a seaway. It would be possible to blow one dry with the other still
partly flooded. It would probably settle out with some nursing, but who's to
know?
