Interesting note on cycle life.
It would take me 150years to go thru 6000 charge/discharge cycles with my boat.
Even if you were to use your boat every single day, it’d take over 15yrs to reach that cycle count.
Not even the manufacturers of these batteries advertise them to last 15yrs, let alone 150yrs.
Cycle life is meaningless to me and my boat except that if I were using Lithium cells, one overcharge or one over-discharge and the cycle life goes from awesome to pitiful.

Subject: Re: [Electric Boats] Tax rebate for going green?
Doug,
A tax rebate would be a great boost for electric boat equipment but a lease would ease the pain for some electric boaters out there. Corvus Energy offers leasing for Kokam Batteries. Looks like a $10,000 battery pack would cost first and last lease payment totaling $300 and $150 per month with a small buyout at the end. Please don't quote me on this look at the website. Kokam Batteries are heavy duty traction batteries now being used in harbor tugboats.
Kokam batteries are very expensive but they offer 100% x 3,000 charge/discharge cycles and warranty. So you can discharge say 50% and theoretically get 6,000 cycles. Also the charge times are under an hour in some battery of their packs.
I would ask your Electric Yacht or component representative about this.

I got an email newsletter from my Senator today and one of his bills is this "S.3137 - Solar Uniting Neighborhoods Act of 2010" you can read it here: http://markudall.senate.gov/?p=blog&id=529ed
I just sent him an email discussing all the various alt energy options (that I know of)(wind, solar, kites, fuel cells) and ask him to amend the bill to include the boating community and to expand the scope to cover all these options.
Since this is a pending bill I would encourage everyone to contact your senators about amending it to include boating. Good for the environment, reduce oil dependence, create jobs.
