Received another batch of photos from Circa which might be of interest. The first of these shows the get home prop and the main prop. Fresh bottom paint has been applied to the hull, fins and rudder and prop speed has been applied to the main and get home props. Also note that Iron Lady is sporting her new 4 blade main prop which will power the boat at 10 knots at 1750 RPM (engine) – some 50 RPM less then before. The prop will be turning at a leisurely 685 RPM at these settings due to the 2.556 to 1 reduction of her ZF280V transmission. The combination of the 4 blade prop and reduced RPM will also reduce the already low noise levels inside the boat.
In this second photo, you can see that the get home system has its own complete keel and skeg. The prop itself is self folding and folds down much like a flower bud so it greatly reduces the drag when closed.
Another shot of the hull around the starboard side stabilizer fin.
Note that the fins and rudder are painted white which allows for easy inspection of the surfaces for marine growth. As the hull coating is ablative, we have never really had to do any scrubbing of the bottom, but this is also a function of the time that Iron Lady spends underway versus sitting at the dock.
Finally, a shot of the bow thruster tunnel and bow thruster.
Cheers
