<html><body bgcolor="#FFFFFF"><div>Alan,</div><div>I've seen the discussion. 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>Sent from my iPhone</div><div><br>On Jan 24, 2014, at 3:20 AM, Alan James <<a href="mailto:alanlindsayjames@yahoo.com">alanlindsayjames@yahoo.com</a>> wrote:<br><br></div><div></div><blockquote type="cite"><div><div style="color:#000; background-color:#fff; 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 reach out with a manipulator & have talked about countering it with</div><div>trim tanks.
