With -23 degrees on Wednesday January 30, 2019 I zip forward 5 days to Sunday February 3, 2019 and enjoy a 46-degree day working on the boat. If you don't like the weather in Chicago, wait 15 minutes.
209. Replaced all fuseholders on the switch panel and tested them. This was done because in the crash test dummy night to see if we could sink the boat, the navigation lights, masthead light and compass light weren't working. The fuse sockets had disintegrated. All lights (and other functions) are tested and are working.
210. Put in a new board where the Datamarine Log was, re-set all of the fuses to appropriate sizes behind it.
211. Rewired the Garmin per NMEA2000, but no change in the data. Won't be able to go any further with this project until the boat is moving.
212. Finished installing the three 12V fans in the bunks.
213. Right sized the fuses on everything everywhere on the boat and made a spreadsheet of the sizes and location of all fuses.
214. Some wires were dangling down in the forward cabin and by the paper towels, put hot melt glue on them to hold them back in place.
215. Changed wiring on switch panels - moved the Compass light wire onto the Navigation Lights. One switch does it all. The switch for the mast display is no longer needed as the wiring for that was moved to the navigation station as part of the NMEA200 rewiring. There are now two Spare switches on the fuse panel.
216. I laminated 5-step directions on how to turn on all lights for sundown, and turn them off at sunrise and taped them onto the navigation station wall to assure we save battery power. The list includes the: Running Lights/Compass Light, Masthead Lights, Windspeed, Boatspeed, and the Mast Display. Leaving all of those turned on would waste 18 amp hours over two days.
217. I got a pool noodle at an estate sale for close to nothing, put wire ties around to hold it onto the plastic 55-gallon barrel that protects the boat from the mooring in the harbor. When the wind dies (it does it a ton more than you think), the boat rides up over the mooring and it is a loud BANG BANG BANG with the can bouncing on the bow that doesn't end. Hopefully this will dampen the noise a bit.
218. Installed the flax packing on the rudder and re-attached cables. I tried to do it the "easy way" and could not get it to work. Finally I made the decision that the only way to get this done was to drop the rudder, it went much faster doing a lot more work. At the end, there are two bolts on the rudder cap, each about 1/2" over-length. I took the Dremel and cut them off to reduce chance of cut feet, cut ankles, or lines snagging them.
219. A side project to understand the electrical usage on the boat develops the following. As we commonly take roughly 2 days to get to Mackinac Island in the race, conserving battery power is advisable. The race allows the running of the engine to charge batteries, but not allows the engine to be put in gear. Charging the batteries with the alternator is obviously noisy, and breaks the peace and silence of sailing non-stop 24 hours a day.
The double ship batteries have a combined usage of 240 amp hours (there is a separate battery used just for starting the engine and not used in the calculations). And then we drain those 240 amp hours, here are my USAGE ASSUMPTIONS PER DAY and then the AMP HOUR RATINGS FOR EACH FOR TWO DAYS:
Running Masthead Compass Light = 8 Hours/day 7.52 amp hours
Head = 15 minutes/day 18 amp hours
Cabin lights 2.6 amp hours
Fans 10 hours/day 84 amp hours
Water Pump 15 minutes/day 4 amp hours
WIFI 24 hours/day 48 amp hours
Wind/Boatspeed 24 hours/day 2.4 amp hours
Electronic display lights 8 hours/day 4.6 amp hours
VHF Handheld 1-recharge 3 amp hours
Tablet Charge 2-recharges 1.2 amp hours
VHF standby 24 hours/day 24 amp hours
GPS 24 hours/day 4.8 amp hours
Mast Display 24 hours/day 10 amp hours
TOTAL AMP HOURS USED IN 48 HOURS: 214
Obviously there are pluses and minuses in actual real use, maybe we don't use the fans because weather is nice, or we don't use the WIFI until we're in the middle of the Lake, things will be different, but probably not more use, just less use of electricity. If charging is needed, the Alternator puts out 35 Amp Hours, or we run it for 1 hour, we add 35 amps to the battery giving us another 7.5 hours of battery life (we use an average of 4.5 amps per hour).
Note: Moving to LED lights all over the boat from incandescent light has saved 70 amp hours over 48 hours almost equal to adding the 3 bunk fans! Nice trade off.
And for reference, shore power charging puts 20 amps into the ships battery, and at the same time 10 amps into the starting battery, or 30 amps total when plugged into shore.
The next owner is really going to enjoy this boat.
