I sort of have a trim tank already with my forward hard ballast tank, I'm just not sure at this point whether or not that will be enough control. A way to deal with varying loads is probably something I need to address, but I don't want to give up valuable cabin space for it. </DIV><DIV> </DIV><DIV>Brian<BR><BR>--- <A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A> wrote:<BR><BR>From: hank pronk via Personal_Submersibles <<A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A>><BR>To: Personal Submersibles General Discussion <<A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A>><BR>Subject: Re: [PSUBS-MAILIST] penetration schedule<BR>Date: Thu, 13 Aug 2015 18:23:16 +0000 (UTC)<BR><BR></DIV><DIV style="color:rgb(0,0,0);font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;font-size:12px;background-color:rgb(255,255,255)"><DIV><SPAN>Brian,</SPAN></DIV><DIV><SPAN>I would add a few nipples and cap them off, you will want them down the road.</SPAN></DIV><DIV dir="ltr"><SPAN>A trim tank may be a good idea for such a heavy sub, unless you have real powerful vertical thrusters. 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. I foolishly made two rather heavy lead weights. </SPAN></DIV><DIV dir="ltr"><SPAN>Are you running your O2 through a ss nipple, is that okay, I am planning to do that for external O2.
