Speed on a schnorkel was 6 knots to avoid tube vibration and damage or rupture of the tubes....much less pressure ear-damage to the crew from wave strikes to the schnorkel head. Likewise, submerged speed on a raised periscope at 6-7 knots on battery power tended to make the instrument useless, particularly the attack scope, also from tube vibration causing unrepairable damage to the optics.
