      Hey! That sounds like fun! Tell us more about this EV, Electric
Vessel, how big, fast, EVerybody asks "How fast" how far. After all, the QE
2 is electric too.Well, her AC "traction" motors are supposed to be the
world's biggest, but no batteries, just Diseasel engines to make power as
needed, more the merrier-faster. After all she doesn't hafta "Plane off"-
like small boats! Guess the miliage is better than her stock steam turbine
drive she came with, a few retrofits ago.

     Of course, think "Displacement hull, like a sailboat. Have had
delightful electric launch rides on the CT river,all you hear is the boat
slipping through the water and all the #$%^& mechanical RACKET from
everybody else out there.

     Ct runs a couple of small car ferries, mostly by tradition, ferries
have been at those locations since colonial times, they hate to break
tradition. Of course they keep bankers hours and don't run in winter, but
the distances are short, perfect for an EV, have 2 boats, and keep one on
charge that yu arent using, switch off EVery few "flites" so they both
stayed nice and juicy. Have the hull make contact with the on shore charger
when it pushes into the slip, and a good Mechanical connect so it doesn't
hafta run, like most ferries ,I've seen, running the engines in gear to hold
themselves in the slip. What a waste ,all that water foaming at the stern
while they run in place, even though it is picturesque. Thing only hasta run
about 10 minutes per crossing. HMMM?? Buy the franchise from the state? They
probably would like to get rid of it. They don't make money, EVen though
they charge buck an a half for a car 75 sense per walk -on. State of CT
would lose money if they ran the Casinoes, I'm SURE! They don't, break for
the taxpayers! The "Indians" have that franchise 'round here.Do very nicely,
thank you!

     Howbout painting the Deck over head black or other dark color? Passive
solar? For sunny daze. Change to white in summer.

    Sounds like a plan!

     Guess you could heat like hell, while uploading and downloading at the
pier, via shore power? Hundreds of amps in to a water tank for the crossing,
with basebored hot water heat in the cabin?

     Good point, anybody that EVer has had a boat, can appreciate this!!!!!

     Whole new ball game, this EVessel  thing, fun thinking about it. Guess
regen braking is a non endity<g>!

     Sailya
