The masts are now stepped, and boat has moved to her summer berth on Margin Street. Engine commissioning went without a hitch, replacing the sea water impeller and the first two fuel filters. The trip out of the boatyard was mercifully routine.
The post-launch checks are not going well. When I powered the Raymarine C70 multifunction display, I saw a message "No Scanner". I have checked the continuity of the conductors in the mast cable, and they are good. The scanner itself, a Raymarine type RD218 2KW radome, seems to have failed. I am troubleshooting with the aid of the Raymarine support forum, but I am sure that I am going to have to dismount it, and return it for intensive care.
In order to use the Raymarine AIS650 in active (class B) mode, I must use its internal GPS with the antenna mounted on the mizzen mast. I have been unable to fix a position. The status LED on the front panel of the AIS is red, indicating a fault the electronics can see. The cable resistance measures a short, indicating that one of the connectors is bad. Troubleshooting is beginning.
