Hi Nanci,
I agree with Mike about falling off and motorsailing if seas are an issue. If you have any wind it does not take much power to increase your boat speed.
On the light side of the wind spectrum I find I can add a small amount of power, 2 to 8 amps (@48-51 volts)and gain a knot or two (or even three) and point higher (make sure you keep leeward weight). At that current draw you can motorsail for quite a distance and the higher point of sail can make a big difference in VMG.

Plowing into head seas was never fun for me. IMO trying to out slug the ocean  raises the odds against you a bit.  I did not enjoy it even when I had my diesel and it will eat up power from your battery bank. But, what I did discover recently is to fall off slightly and use the EP to keep moving in the in the direction I need to go. Much easier on the boat and keeps you moving in the general direction you need to go and it does this quietly. That works for me.

Lauderdale to the Bahamas, the wind is usually on the nose. If I have to tack, I run out of daylight to make it, so I want to feel assured that I can get there under EP if I need to ..about 50 miles.

Actually I still have power to spare from the generator so I usually charge up my 12 volt house bank at the same time. In reality I'd only do that when there is no wind which is not very often. The wind usually picks up soon enough and I gradually start cutting back on the EP as the wind picks up. Pretty soon I am sailing again and shut the generator down. I could also have put in a bigger diesel generator and powered the EP system from it too but personally I'm done with diesel.

> BTW I changed the topic for this reply. I have a friend who is on his second EP system. The first one was a homebuilt setup with chain gearing a little noisy. A few years back he sailed from St. Martin to St. Thomas on the way back he was demasted. He used his EP system and Honda Generator for twelve hours of motoring to get to St. Criox for repairs. EP systems work well on sailboats. But, as I mentioned to Pete you have to be ready to embrace them. But, IMO they just make a whole lot of sense for a sailboat thats why I decided to go with it.

I don't cruise much, mostly daysail multiple days per week with overnights within 35 miles, but that is more than I see most of the sailboats doing around here.

According to the USCG 2009 statistics, registered power boats outnumber auxiliary sailboats by about 98 to 1. Looking at just the sailboat population, we know that the 26' to 40' range is the sweet spot for electric conversions. Now we're down to less than 51,000 boats in the US out of over 12 million mechanically driven boats (boats with motors).

I own two boats in this range and won't convert one of them due to the performance hit while sailing and motoring, and I'm a big proponent of the technology.
