Let us introduce you to FPB 64-3, Iron Lady, about to start her sea trials.
Iron Lady is the first FPB 64 to have a stern extension bolted on. We will have performance numbers on this shortly and report them in due course.
Note the nicely faired buttock lines.
The rudder is huge relative to the steering loads at sea, optimized for close in maneuvering. It is built to twice the ABS rule scantling requirements. Note how clean it is when seen from aft. This is a key ingredient in prop efficiency.
First thing on launch is check the hull penetrations, which in the extension is a depth transducer.
Iron Lady afloat. After 30 years, and more launches than we can count, it still gives us a buzz to see a new design sitting on her lines.
Stay tuned. There are more photos coming soon.
