1 knot submerged is a bit conservative. Remember when submerged you are not burning diesel but rather drawing on batteries. Where you lose fuel is in the recharging of the batteries. The deeper the discharge state of the batts the more fuel is lost.

That being said you should get plenty of life out of the batts at around 3 knots.
