<div><font size="3">Alec imparted some education to me one time on roll
control. When he added side ballast tanks to Snoopy, I asked why he had
mounted them so they were partially above the waterline when surfaced. He
explained that when the vessel rolls to one side, the tank on that side then
becomes more submerged and provides more "lift." Simultaneously the tank
on the other side rises and provides less lift. The net effect is
automatic roll dampening.</font></div>

<div>Hi Alan, Going to add a lot of weight to the bottom of the
concrete ballast , at the very bottom. Need to cut an access hole in
that area so I can put lead bars in there and bolt them in.</div>

<div>Another interesting video Brian.</div>
<div>I see what you mean about the stability.</div>
<div>Pity you couldn't have sunk her completely to see how stable </div>
<div>she was once that big conning tower was under the water.</div>
<div>What's the next step?</div>
<div>I am not sure I am getting all the posts so apologies if I'm
doubling </div>
<div>up on any one else's comments.</div>
