    On a recent trip to Alaska I noticed a lot of good looking aluminum
    fishing boats and some cruising boats. What are the pro's and cons of
    aluminum as a material. I can think of a few cons besides
    electrolysis. In colder climates I was wondering about condensation.
    Is this a problem behind headliners and paneling?

    There are a couple builders that I know of who build Aluminum
    Catamarans and monohulls and they seem to be using surface drives in
    greater numbers. I am thinking this is because of the lightness of the
    aluminum platform can utilize the speed resulting from these types of
    drives. I have never liked stern drives and have had mixed results
    with these in salt water. Is the surface drive more robust and less
    vulnerable to electrolysis? or just for designs meant for maximum
    speed? Just some thoughts that I was wondering what the listee's
    perspective might be
    on Aluminum and surface drives.
