For that reason, I would guesstimate that 25% of this additional power is simply wasted in generating air bubbles around the blades. That being the case, then at a Trial Displacement of 53,900 tons, a tad over 34 knots would appear to be a top number. For a Light Ship Displacement of 51,000 tons, 36 knots would seem to be possible.

因此，我猜想在这样的情况下我们所增加的动力中将有25%会被空泡白白浪费掉、在这样的情况下，于53900吨的公试排水量下，34节的航速将会成为其极限航速、而对于轻载51000吨的情况下，36节的航速将会是可能的。
