Which hull shape is better for regen?

Which hull do you think would make the best electric conversion, in terms or regen, battery location, or any other observations you might have? Looks like the Cherokee bilges might be a bit shallow for batteries?Thanks!See More

Starter advice for Max's New Electro Project

I'm on the hunt for a cheap old cruising sailboat to electrify for Lake Michigan and future long range cruising. I'm currently considering a Cal 30-1, Chris Craft Cherokee 32, and various Cheoy Lee Offshore models from 30 to 40 ft.Before I buy a boat, I figured it would be wise to get some input on what to look for or avoid in a good conversion candidate. Any general input appreciated. Most boats I'm looking at have an old atomic 4.I'm considering a 10kw electric yacht system, although I keep…See More

SolidNav UpDate and GEN4 Converstion

I bought David Carrolls Catalina 30 with the SolidNav Explorer in it that didn't work. It was giving the 3 blinks code on the LED flash and sometimes 4 blinks on the LED flash.I called Thunder Struck Motors who are extremely smart and helpful people and talked to them about what would be  the best route to take to fix the system. After exploring all options. I decided to buy a brand new GEN4 Controller, the wiring harness, and the new style better throttle control and have it all programmed…See More

Helm Instrumentation Project

Recently I built a helm instrumentation panel so I could keep and eye on battery voltages and current draw on the propulsion bank without leaving the helm while underway. It worked out pretty good though I still have to mount it permanently. The links to the process I went through are here:http://biankablog.blogspot.com/2013/02/instrumentation-project-part-one-plan-a.html…See More
