I find when I take a passenger, even my daughter Roman who is light as a feather, I am always quite over weight. That is no problem at all in a Gamma size sub because the vertical thrusters have enough jam to stop the sub hitting bottom. A trim tank would be good to keep you closer to ideal weight, or have lots of small weights to take out.
