Simple matter of math. My ICECO 45 qt will draw 3.7A at 24VDC when running, watt equivalent to 7.5A at 12VDC. That would mean about 13 hours for a 100AH 12VDC battery running from full to zero, though the freezer doesn't run all of the time except when its very hot and set at the lowest setting...

Great idea for the steel scrub pads...I'd used aluminum foil, but they seem to chew through it anyway.

Should I be happy that my tabs are hydraulic? It sounds like these are having a high rate of failure.

I built and maintained a web site for international discussions about "Forest Soils" sourced at the U Washington for decades, so I am somewhat familiar with what is involved in creating and managing sites. That sprang from the privilege (?) of seeing what could potentially be done with networked...

This is my first attempt at a movie on this site. I was taking the Black Ball Ferry from Victoria, BC to Port Angeles, WA. Hopefully, this link to Youtube of a movie I made of the electric harbor boats will post OK. Try clicking the link below... Electric Harbor tour boats in Victoria...

Bob; You are another class of waterman than me, obviously, in both skill, experience, and patience. I worked 35 years with another forestry professor that had a 57 ft, 15.5 ft beam 100+-y-old wood sailboat (Mary Hillyer) he bought as a derelict and restored beautifully. He had re-rigged the...

Speaking of sailing...just peeked out my window and saw this in the outer part of Oro Bay. Gone in a few minutes. Greenland-style paddles too! These guys were really moving, maybe getting ready for the WA360 or Racd-to-Alaska. Anyone ever deploy a sail on a C-Dory? It could work today, as long...

That is so cool. If you put a level camperback over the CD22 cockpit, that could probably double the area. I fixed one 175 watt semi-rigid panels on the CD22 over the roof, and one over the camperback, with bungies. The one over the roof is quite stable, and I bring the one over the camperback...

I was warned to never start my motor with all of the electronics running. I just switched it off and then back on when I started the motor, which was somewhat of a hassle. My initial change, back when Li was crazy expensive, was one 100 AH 12 VDC with a DC/DC charger between the starter and...

The idea of cruising the great PNW fully-electric is compelling. Many, if not most, people that do it are limited to hull speed or less (trawlers and sailboats), though typically with longer boats and thus somewhat higher hull speed. Trawlers can only motor. Practically, sailboats almost always...

Agreed on all accounts...

Sorry if this is wordy, but I think it is important, as people are smelling raw gas when operating their boats. As a retired research scientist (>40 years) that purchased and dealt with millions of dollars of crazy expensive, "state-of-the-art" electronics, hydraulics, and other gear, I would...

I would advise anyone that has a boat to check all of your hosing, from the fill to the outlet. When I bought my 2003 model CD22 in 2015, the hoses were cracked on the outside, and you could see bits of black stuff, probably deteriorating fuel hose, in the filter housing. I replaced all fuel...

Earlier, I had a Honda 9.9 HP kicker mounted on the starboard side of the transom beside the 90 Honda on my CD22. It had remote tilt, start and throttle from the helm with controls beside the main. Sounds nice, but it certainly wasn't. The 100 lb+ extra weight on the transom and the tilt to the...

Agreed, there are significant advantages to 48 VDC. Problem is, I already have much of my system at 24 VDC, including my beloved Minn Kota bow mount 80 lb motor, and my Renogy DC/DC charger that combines solar with the alternator and also charges the starting motor with solar. I'm going to think...
