Final rudder work

I least it is close.  Just have to make new longer tie rods and finish the tiller and make the extension and install the lock down fasteners and ...

The list never seems to end.

Here's the final linkage arrangement.  I thought about moving the pivot forward and adding a lever off the back of the tiller arrangement so the rudder arms could be lead rearward, but this seemed simpler in the end.  And not really anymore in the way.  You might note that the rudder arms are a bit angled.  The idea of using an ackerman alignment, or insuring that the inner rudder makes a smaller arc through the water than the outer rudder, comes from cars.   A reasonable starting point for a boat system would be to aim the rudder arms to the pivot point of the boat, or about towards the keel.  I somehow managed to cut the tie rods about 2 inches to short to accomplish that so new ones are in the works. I also am going to install inserts into the cassette mounting sleeve so I can bolt the rudders down to the sleeves so they will not float up. up and away.

Just a shot of the forward deck panel in place and properly trimmed to fit.  The rear one has also been sized now so both can be finished and painted.  This, with the forward cover in place and the rear one removed is how I envision the boat normally being sailed. I will,however, make sure the rear one can be fitted and sealed when sailing just in case.  Pictures of a how that all fits together next time.

Another shot of the tiller and rudders from forward on the boat.

We are still on track for a March (though perhaps a late March) launch.
