Re: GV10 Stop and Start Project

You can use something water tight for floatation (water bottles... not so sure). If you are worried about water, just leave a limber hole large enough to drain but not enough to let your flotation out. You can add a hatch to allow you to remove/change flotation devices as well.

Not a bad idea...

Ha! Figured you’d “have a guy” with the expensive version.

Re: ST21 Hybrid Powered "SKINNYDIP" Noosa Australia

Couple hundred ohms of high watt resistance and a volt/ammeter. Any that you lost will work. I recommend an ammeter and potentiometer in-series to monitor draw and a voltage monitoring relay set for the desired drop voltage. That will let you set the draw rate and walk away. Remember that I higher o...

Re: Question about OB 15 plans.

remember that you don't need "accuracy" with the permanent ply. The plans/notes should tell you that you need a gap between panels and frame/sides. The real accuracy is needed in your jig/mold for the initial stitch of the hull (sometimes JM uses the frames as the jig). Make sure you take pics. We a...

Re: ST21 Hybrid Powered "SKINNYDIP" Noosa Australia

Yes, serial. My volt works that way. Unlimited range as long as I can find a petrol station. My limiting factor is the dang lipo won’t charge efficiently unless plugged into mains. Super caps fix that. Once my bats implode I’ll be swapping and getting a metric crap ton more efficient petrol use. Ass...

Re: ST21 Hybrid Powered "SKINNYDIP" Noosa Australia

I’d stick with what you have for sure. But should you ever decide to go pure E with diesel generator, super caps are going to be the ticket. The big win got pure E is the ability to charge fast, sustain full discharge with no change to charge cycle, and the ability to disregard charge/discharge cycl...

Super capacitors? Considered them? Haven't even heard of them! :lol:
Well, shoot. I figured you’d have heard of them. They are replacing batteries in many applications. I’ll see if I can find some 48v descriptions and PM you
