[StartQuote] Roy, my PT-157 model has three motors/shafts/props and when running it throws up the identical rooster tail and 'trough' behind the fantail (stern) when running at higher speeds such as I see in still photos and film of PTs of the period. It evens has the pronounced yaw when running in reverse as noted by skipper in an article a read some time ago.. I can say that given the running characteristics of my PT-157 very closely (if not exactly) emulates the those of the full scale boat, the rudders provide ample maneuverability. It surprised me as as well considering their smallish size however whether be the total square inches of area (when all three rudders are added together) or the rudders' placement right in back of the props or maybe even both, it is fine. I'm not aware of any complaints by Skipper Liebenow of the 157, of maneuverability in this regard but will ask the next time I speak with him. To the point that the rudders maybe were shorter as they patrolled hallow waters, the props were about another 12 to 14 lower then the bottom of the rudders so I don't think that was a design limitation and even here the center prop/rudder were much lower then the outer props/rudders. [b]The PT-157 model emulates the full size version in maneuverability very well....[/b] [IMAGE]http://i130.photobucket.com/albums/p249/ptboats/Bridge%20Carney/I-WLseries1frameunksoonafter131248.png[/IMAGE][EndQuote]
