In 2013, I made a few minor improvements:
I purchased an electric outboard for the dinghy. The new outboard is very light, and so clean I'm happy to store it in a berth. The motor, a Torqueedo Travel 1003, is satisfactory but not at all thrilling. It is quiet, but not soundless; it is powerful, but not strong enough to plane the dinghy; it has a lot of distance, but not enough to motor to Watch Hill and back on a single charge.
I added a solenoid for the CNG gas stove. This was a very simple safety-related improvement, which makes it very easy to cut off gas at the source when the stove is not working.
I installed an Automatic Identification System (AIS) transceiver, the Raymarine AIS 650, connected to the VHF, radar and chart plotter. It operated through 2013 in passive mode, listening to the broadcasts of other vessels, and plotting them on the screen.
In order to operate the AIS in Active Class B mode, in which Rune broadcasts her position and vector, the AIS650 must use its own GPS receiver, separate from any other, like the Raystar 125 we have been using all along.
When I tried to install the new GPS antenna, associated with the AIS, into the mizzen mast, I was unable to remove the old cable. The cable for the old GPS had been glued into place when the mizzen was repaired from the dismasting seven years ago. Therefore, I tasked Taylor and Snediker Woodworkers, LLC, to rebuild the mizzen mast, beginning in the Fall of 2013.
When Wade, at T&S, tried to free the GPS wire, he had to open the mast. He found a piece of heavy-duty electric wire, apparently a length of #14 extension cord, had been fastened into the hollow center of the mast from its foot to its head, with stainless steel wire staples. The wire had been cut near the foot,and its end stuffed inside the mast. Similarly it was broken about 2 inches short of the exit port at the top. I suspect that this wire was used to carry the HF signals from the LORAN antenna which was on the head of the mizzen when I bought the boat. That wire was so thick it prevented me from passing new wires through the mast. Of course, its impedance would have been completely wrong for the HF signal from the antenna and the lack of a coaxial shield would have injected noise into the receiver, and effectively reduced the system sensitivity.
At any rate, the mast was nicely scarfed and rebuilt. The cable for the radar was passed from the entrance hole near the foot of the mast to an exit hole about 8' up, where a bracket holds the radar dome. A pair of electrical leads were sent to an exit point near the radar bracket to supply power to a cockpit lamp. A coaxial cable was installed from the foot to the GPS platform about 12' up. A grounded Ethernet cable was routed to the exit point near the head, where it was connected to a WiFi receiver.
I also ordered a new mizzen sail, from Doyle sailmakers. The old one was more than 23 years old. As soon as we can complete the 2014 spring outfitting, we'll try it out.
Now, in the middle of April 2014, Rune has been launched and we are awaiting a weather window to step the masts.
