Re: [Electric Boats] electric prop and re-charging

 

Thanks, I'm no authority on the White family, just happened to visit 'the T'ville boat shop' just before the time everyone was hooked up to the internet or before I knew Robb White wrote for Wooden Boat and other. But he seemed quite happy that I liked pokin' around on the water, and knew many of the same watery places in which one can poke. I hope some of the water oriented Whites will continue to 'slap'em together', their collective good workshop, boating & plain ole pokin' around example has enabled lots of people to begin playing with materials and designs - and combine old methods with new materials.

So, . . . back to electric boating and extended travel with electric.

An extended travel electric boat with the ELECTRIC wagging the dog's tail, not a sail-boat with small/minor electric power is what I'd like to construct, and have the workshop space and time in which to do so.

Lee-board(s) could be added to the tunnel-stern designs sail to increase the range. Sails would be in proportion to the size of the craft as with canoe or kayak sails to those boats.

Each 'easy off the shelf' change of state seems to be expensive :

solar to electricity,
internal combustion to electricity,
water/prop re-charge to electricity,
wind to electricity (docked),
or stationary bike to electicity,
and so on.

And electric storage is quite expensive for the amount of total mileage/life of the battery bank/storage, though as one of the links pointed out above that the slower one can travel, the more mileage comes from a battery charge, and I suppose that also means a bank of batteries could ultimately pack in double or triple the miles or more than storage banks that were quickly dis-charged.

I'll continue to read the links and posts, thanks for continuing to consider and respond to this thread.
