If you want to stick with Excel, one can still purchase Microsoft Office for a single computer for the life of the computer. You don't have to pay an annual fee as for 365. https://pcsalesonline.com/en/office-acc ... udent-2021.

In the early days of these batteries one could only buy the individual cells and I had to build a battery bank from scratch. My truck was running at 120 volts and my boats at 36. Between the two I had 44 kWh of storage.

I have been using LiFePO4 batteries as a primary source of power for 12 years and have not had any problems with them. I bought 40 180AH CALB cells in 2012 to power a small pick-up truck conversion I built, and used them for 8 years until the truck body gave out. I then transferred them into a...

I found an interesting you-tube video that might help you. In addition to what the video suggests, I recommend you also soak the shaft with WD-40, or preheat the wheel around the shaft with a hot gun (hair dryer). That will cause the metal to expand and help loosen the joint. Don't heat the...

If you are a heavy power user (say hot pot and electric cook stove, hot water heater) I would not plan on using solar power to provide your only source of power. A solar panel laying on a relatively flat surface (not oriented to the sun) will produce about 10 watts/ square foot. Thus, over a...

OK Don, Let's get into the weeds. Battery technology and chemistry is constantly changing so one needs to do a lot of research before using Lithium batteries for starting. If you are not willing to specifically match a certain battery with the outboard motor and its charging circuit, I would...

I agree that Lithium Iron Phosphate batteries are the way to go for house power, and I have been using them as my main power source, and house power, for 12 years now. However there is one major issue with them: NEVER HOOK ONE UP DIRECTLY TO YOUR ALTERNATOR. Always use a separate DC - DC...

Yes the inflatable PFD's (personal floatation device) are more comfortable and most people use them (I do). However there is one aspect of their use that is different from the foam PFD's, and often forgotten. The "activation bobbin" has to be replaced every three years, or the PFD does not...

If you have the choice I would recommend having a separate lead acid deep cycle battery for the house loads and a starting battery for the motor. Charging can be from the alternator with a switch from one to the other. The other option is to charge the house battery from shore power and the...

When I first looked at the 22 ft cruiser I had the same concerns about the V-berth. I am 6'1" and have a bad back. Getting in and out of the berth was an issue for me, so when I ordered my cruiser from NMI, I had them modify the main cabin so I could put two berths in it. The port side berth...

Yes the data I report are based on using the two motor simultaneously. When I run at 5 mph I am putting 1 kW into each motor. Since each motor is rated at a maximum of 3kW I could potentially cruise at 5 mph by putting 2 kW into only one motor. I have not tried it but I expect that it would...

The summer is pretty much over for us and I have put WATT NOW "to bed" for the winter on its trailer. We spent a total 19 days on the water this summer of which 11 days were overnight. This has given me a good idea on how much electricity I use under a variety of conditions. With just my wife...

OOPS! I missed answering some of your other questions. First, I have written a book about electrifying cruising boats and it is available at Duckworks Boat Supply. It is called "Plug-in-Boats: a primer for converting to electricity.". I have talked about my experience and hard won knowledge...

I have been cruising electric in Puget Sound for 26 years now. I had three 26 ft St. Pierre Dories before the C-Dory. Electrifying a cruising boat is not that difficult if you are content with cruising at or below hull speed (like sailboats). I have two 3kW outboards on my C-Dory, which is...

Hi, I had a 22ft cruiser built by NMI this year. I had a great experience with them and Michael Millison (production VP) was very helpful (maybe because I was having the first electric C-Dory built??). I first contacted Michael in August 2023, placed my order in early October and they...

FYI The 22 ft C-Dory comes with two options for cabin height - 6'2" and 6'9". I am 6'1" and when I ordered my 22 ft cruiser from NMI I was able to specify the higher top. My wife and I were not comfortable trying to sleep in the forward area so I had NMI not build the sink and stove area. They...

To respond to some of Bob's comments: I have not had problems sleeping in small spaces in the past but I am no longer as flexible as I used to be. I have a old back injury and scoliosis of the spine that limit the contortions to which I can subject my body. It is not the length of the berth...

The pedestal is electric (120 V shore power), but since it only uses 250 Watts it can be run with a small inverter off the house battery. I bought it from Progressive Automation who have their US office in Arlington WA. The cost was actually less ($350) than the hydraulic pedestals sold in...

I have found that the C-Dory 22 and the 25 as usually configured are not very comfortable for sleeping if you are larger and older. The forward cuddy is too low and difficult to get in and out of. I am 6'1" (and 76 years old) and had to really scrunch down to get in and out of the berth. When...

Yes there will always be variability between boats, motors etc. We can however try to normalize to variables that are universal. David Gerr in his Propeller Handbook attempted to do that using his knowledge and empirical data. Using his equation I calculate that it takes 2 shaft horsepower...
