| Of course the downside of having the prop in all that lovely uninterupted water flow is that the rudders are nowhere near the wash. Hence the two rudders to try to compensate for this.
Compare this with a U-Boat where both rudders and both aft planes are directly in the prop wash making them very effective. I was actually very surprised at how well my Revel U-Boat steers with no modifications to any of the control surfaces.
It will be interesting to see how well this boat manoeuvres. |
