Say hello, sailing world, to Westley. Born perfectly yesterday, 10lbs, giving our sis / his Mom a run for her money. His Dad Joe is a sailing captain, mom owns a Santa Cruz 50, Aunt & Uncle with Ravenswing; well let’s just say he has some sea miles ahead of him.
Westley doesn’t need it yet, but the rest of the crew wants the toilet back. Work proceeds.
Second coat of paint went down today, and all the new hose routings were cut to fit. One more paint coat and the plumbing reinstall this weekend will put the head back in business.
Highly-credentialed multi-huller Jeff visited with his soldering iron during a road trip this week. He donated these resistor boards to the lithium battery cause, and did expert wire connections. what you’re looking at (the green circuit boards mounted above the batteries) are charge balancing modules to regulate the pace at which the four “cells” of this battery bank rise in charge voltage. The risk in an LiFePO4 bank is the cells getting out of voltage balance from their neighbors, and potentially ruining sections with out-of-range values. With these little control boards, when one cell reaches 3.6volts (its full charge), the incoming voltage is converted to heat in those blue resistors. That cell is effectively bypassed from further charging while the others catch up. That’s as simple as I can say it, but there’s more going on with the numbers. It’s a crude version of a Battery Management System, and we’re judging it sufficient for our solar-only gentle charging regimen. Coming up soon we’ll install the CellLog that monitors and alarms each of the four cell voltages that get out of range. That will complete our safety installation.
We found some time to get back to the navigation system. Today was the first time to fire up the radar dome since purchasing it from a San Juan Islands f-31 about five years ago. Anxious moments when we hit the power button on the chart plotter…
And with zero operating knowledge or adjustments, up came…YESSSSSS! As soon as the autopilot install is done, we’ll get out and test/tweak/learn all this gear.
Final carbon work on the autopilot mount:it’s bonded together now, faired and primed. Paint coat tomorrow if this rain departs for points east.
Last Sunday Dad and I were on the Bayshore freeway and I thought I spotted a huge mast. On the way home, we exited towards the Oracle campus, on the hunt for Dogzilla. Visitors to our Santa Rosa build shop might remember I had this boat’s photo on the door for inspiration those years.
We all know what it took to build our new 54′ mast. This one is 223′, got used for one regatta, and now serves as a statue. Now that’s rich-guy extravagance.
