<div>Alan,</div><div>You may be underestimating the air volume in the main MBT. I also predicted the sub would do a nose dive suddenly, but that was before the addition of the new light weight second MBT up front. There is enough MBT above the water line when most of the sub is submerged. I think Brian has it, pity he couldnt de a test dip.</div><div>Hank</div><div><br></div><div><br></div>
