    Darcy, I'm sure she will be out sailing you in a few months if she's already going to the 2022 South American Championships. Kids get really good really fast. Especially when they love something. Enjoy the ride and do make that ocean crossing with your daughter happen. There are lots of ways to...

    Yes, I have 12 Battle Born LiFePO4 12V, 100 Ahr batteries. I went that route because of battery performance and the fact that there is a Battle Born distributor in Hawaii where Kolibri will be as of late June / early July. Other options were LifeLine (no HI dealer) and ePropulsion (form factor...

    Yeah...my oldest daughter is quite the sailing geek. She starting sailing at age 6, raced FJs and 420s in college, crewed on a ~35' Jboat for races in college (can't remember the model), just finished her first crossing to Hawaii from Mexico, and is busy coming up with all kinds of adventures...

    I've been following the Sailing Uma YouTube channel for a while. They are definitely a great source for real world information. They also have an awesome approach to how they go on their adventures.

    Thanks for pulling the actual numbers. Note that the numbers I threw out above all had "~" as in "approximate". I certainly didn't start a timer with the charge activities :-). You also hit the nail on the head with, "motor or motorsail for multiple days on a schedule". This is something that...

    I will definitely post more on the regen when I get a chance to test it out. Wind has been super light recently, but usually picks up in mid to late March. My daughter and I will be doing a multi-day trip in that time frame that will give us plenty of time to characterize solar and regen charging.

    I was in SF Bay where there definitely are some currents. Even with a diesel motor I pay close attention to the tide charts.

    After motoring around with the shipwright the day Kolibri went back in the battery state of charge was ~85%. It was back up to 100% in less than 2 hrs. After the 24.5nm trip I charged it back up to ~85% state of charge because I was heading out of town for a week. That took about 3.5 hours. Both...

    smokey73 - as you noted the cost & weight trade was a wash. That leaves other benefits & liabilities. The biggest factors there are reliability, maintenance, quality of life while motoring, and environmental impact. Electric wins out on all of those fronts. I'm also an engineer and have been...

    Yes, I realize that it will slow me down in regen mode. I did manage to do my homework before spending > $20K.

    I have the engineer's estimates which I've already found to be extremely conservative. Range depends on how fast your are motoring. 2kts gets you 100nm and 4kts gets you 22nm based on his calculations. He did admit that he uses a very healthy margin of safety in those numbers and from the few...

    I recently had the original Volvo MD7A removed from my 1981 Morris Annie and replaced with an ElectricYachts Quiet Torque 10 Electric Motor. The new motor is powered by 12 Battle Born 12V, 100 Ahr batteries wired in series / parallel to result in a 48V, 300 Ahr system. Battery charging is done...
