The smallest sub I know of with a manipulator on board is the Deepworker. No exfra tanks there. Metacentric vs CG works in all directions. Yes, you get movement and no it's not a problem in my experience. I did operate the bigger subs but also smaller ones, to include Aquarius, briefly in a DW, plus three different K-boats,
so speak with some experience. You put everything you imagine on a
small sub, you get a big sub. In any case, It's probably best to think of a psub as a work in progress. Get the boat done, go play, scratch head, get more work done, go play, scratch head......and so it goes.</div><div>Vance</div><div><br clear="none">Sent from my iPhone</div><div class="yiv5803638844yqt8075494090" id="yiv5803638844yqt53812"><div><br clear="none">On Jan 24, 2014, at 3:20 AM, Alan James <<a rel="nofollow" shape="rect" ymailto="mailto:alanlindsayjames@yahoo.com" target="_blank" href="javascript:return">alanlindsayjames@yahoo.com</a>> wrote:<br clear="none"><br clear="none"></div><div></div><blockquote type="cite"><div><div style="color:rgb(0, 0, 0);background-color:rgb(255, 255, 255);font-family:HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;font-size:10pt;"><div>Vance,</div><div>a couple of people have mentioned lately the problem of the shifting of</div><div>balance as you
