The new rudder
By Dermot Tynan, about 11 years ago.
Thanks go to Colman Corrigan for designing and building the keel and rudder. The keel follows the traditional NACA shape, with a rounded leading-edge, tapering off to a narrow trailing edge. It is approximately a 6318 shape, with the maximum width being about 36% of the length of the cross-section. Overall, the keel is coming in at about 750mm from hull to the end of the bulb, and about 240mm from front to back. That's a 3:1 aspect ratio.
Sailboat Guidance System

A quick look at the almost-complete Sailboat Guidance System (SGS). The board on the left is Igor. Otto is on the right, and the main CPU (Mother) is hidden underneath. The ribbon cable brings all the I/O to and from the boards. The red insulating tape is to remind me of some of the last remaining wires which need to be connected. You can also just about make out the DC/DC converter which is just underneath the ribbon cable at the bottom of the picture.
Latest on the hull
By Dermot Tynan, almost 11 years ago.
Here's a quick sneak picture of the hull with the wiring harness complete and the decks sealed in place.
The keel is still only temporarily installed so the main compartment is again flooding with sea water. The bow is still slightly down in comparison to the stern, but this is mostly due to the flooded compartment. Also, the keel still hasn't been moved back, yet. That will happen this week.
The rubber hits the road. Sort of.

Due to other, exciting distractions (which I will mention in a later post), I haven't had a chance to keep the blog up to date. Still, work progresses on the boat, and that's the important part. Last month, with the keel now in its new position about 30mm further back along the hull, and sealed into place, it was time to add the electronics board.
