Well said John! We are so spoiled with being able to hit the accelerator be it on our boats or in a car and move as quickly as possible to the next point. I think we would all benefit from slowing down and enjoying the ride! That's why I'm a strong believer in electric propulsion and it's benefits.

As far as I'm concerned the only problem with electric motors is lifestyle. The infrastructure didn't need to exist for refueling..
100 years ago the lifestyle was no motor and maybe a sculling oar.30-50 years ago it was gasoline and infrastructure to ensure refueling.Today(and in the future), it will be electric with virtually no infrastructure for a while, then when a viable infrastructure(and better batteries), exist, electric will be the way to go.I say today . . . and work with what works and what's available.I say slow sustainable speed under power( maybe about 2 knots or so).There's a speed figure for boats called "natural speed". I read about in a boat that came out about when outboard motors were becoming popular, and the formula involved calculation friction and derived a speed at which a boat can maintain(once reached), using almost no power . . . that is, the point when energy usage(to "maintain a speed") begins to greatly increase.If a person uses an electric motor smartly(which, for the most part, we don't want to have to do), the energy(watts) to maintain the progress of the boat can be made up with solar panels.BUT . . . of course . . . NO ONE really want's to go "slow" in a sailboat under power and EVERYTHING is valued at maintain hull speed or near HULL SPEED.You got to say goodbye to HULL SPEED being the determining "value" of an acceptable speed.LEARN TO SAIL and learn to live a more leisurely life(style) . . . THEN electric will be worth it.John FrancisOn Sun, Mar 18, 2012 at 11:15 AM, Nanci <nancishouse@aol.com> wrote:
Hi, I'm a cruiser and the numbers don't work for me (yet). Waiting for the time when they do. I cruise the east coast and the Bahamas.

Subject: [Electric Boats] cruizing sail boats
With the fuel questions out there, is it really viable to concider running a cruizing sailboat on electric power and not get stuck waiting for batteries to charge. The concept is where we need to go, but the coast is scarry for this sailer on a budget. Convince me, so I can spead the word. Thanks for all the time you all put into this, it really helps us beginners alot.
