    Actually windmills are not an option - even the yachties are binning them in favour of solar - they just don't produce enough energy.

    lots of discussion on various such tech, let's give them 3yrs and then we are talking. Would love to compliment my 600W panels with another 300W on the lower helm windscreen, nice slope and with the proper sideeffect of cutting solar gains in the helm area
    Wont be able to see as well at night, no worries, go up to the f/b

    let's see what's the price going to be and WHEN! Electrochromic (sp?) glass is another smart development, you don't see it used often though even a decade after launching...

    cheers

    Surely the OP is right in wanting a quiet anchorage, prolonging the battery life, both over his stay and the intervening years, is a welcome bonus. Or have I missed something?

    I enjoyed Hurricane's original thread and would like to see some figures for the season. Unless I have missed the post.

    Same with lithium batteries; my son tells me that you can only charge them from 30%-70% capacity if you want to get more than 500 recharges, so the usable capacity is only 40% of the quoted Max.

    ....not much different to lead acid bulk charge from 50%-80% except the weight and the ruinious cost of lithium. You need to very careful reading promotional leaflets that you have the technical knowledge to see through the hype.
