    I would like to know something about installing of ICCP - systems on yachts in the 200' range.

    1. Does it make scence?
    2. If yes, what system would best?
    3. Any problems with sidescansonar or related installations?
    4. Any problems with under water lights?
    5. Any dangers in touching the hull duing the workprocess?
    6. Any danger of marinelife?

    Ship operation would be mostly islands of pazific and indian ocean.

    Regards

    1 Yes it does make sense it is commonly used on steel hull yachts of 50m (165ft) upwards. And I highly recommned it
    2) I have experience with two systems Marelco http://www.ramsaygroup.com/emcs/emcs.htm
    and Cathelco http://www.globalservicesltd.co.uk/Content/cathelco.asp
    I have no preference for one over the other.
    3) One yacht I worked on had sonar and it was never affected by the system.
    4)Never encountered any problems with underwater lights.
    5) No problems touching the hull at all. (very low power)
    6) No danger to sealife apart from the killing the nasty growth that you are trying to stop.

    If you are considering fitting the system I would recommend you talk to the companies that supply the systems they fully understand the issues regarding location and setting up for different types of cruising etc.
    You also will need to contact your Classification Society as you will be putting some (small) holes in your hull.
    Maintenance is limited to an underwater inspection every couple of months or so and visually checking that the settings on the control panel are correct.
    Generally they last about two years and need to be changed during dry-docking.
