    Having cancelled the order at the beginning of December due to the 30 extra carriage I have bit the bullet resigned myself to the extra costs and reordered.

    Guess what -they have accepted the order and it has now been despatched with just the 10 postage!

    With just the import fees to pay now you can imagine how pleased I am and cannot wait to start building it when it arrives.
    I used to be indecisive, but now I'm not so sure...

    Don't know if you saw my post on the PBO forum but I am now wondering about powering the system. I have never left my shore power on when away from the boat as I have never been sure of the effect on the batteries of being charged allbeit on float by the Mastervolt charger for weeks at a time. I still am not convinced and am thinking a 12 volt power supply direct from the shore supply leaving the batteries isolated and not on charge. Have you any thoughts?

    My method of keeping the batteries up to snuff when I am away is the leave the battery charger connected via a seven day mechanical time switch, set to come on for about one hour, twice a week. This is similar to the type of switch I use, though mine is entirely mechanical and was a lot cheaper. http://www.tlc-direct.co.uk/Products/TCCPU7.html. With the added drain of two antifouling units I might extend the time.

    EDIT, I just found the type I use http://www.argos.co.uk/static/Produc...7C14418710.htm

    I would say this was reasonable if you have a shore power connection anyway.
    We used to do this with our elecs on the last boat - no battery charger, so when connected to shorepower we had a rectifier and I connected that into the boats electrics (having isolated the battery!) then carry on using stuff without worrying too much.

    How do you decide how many of these you need for a specific boat - for exaple a 39ft catamaran?

    The magazine article says one unit for a mono-hull up to 32 feet, therefore a 39 foot cat is probably going to need 4 units. I say probably because the article was basically considering relatively wide beam motorboats, with the unit placed well aft to give best protection to props and rudders. On a 39 foot catamaran it might work with one unit in each hull, placed about two thirds of the way back behind any stub keels or dagger boards. I base this on the fact that if you put one unit in a 32 foot motorboat, aft of the propellers as they illustrate, it is also trying to protect the bow part of a boat which is over 25 feet away.

    Default 2 Jaycar ultrasonic kits for sale (Germany)

    Hi All
    just to let you know, I have 2 Jaycar ultrasonic kits for sale, sitting now on my shelf in Germany. I ordered 6, 2 of them I don't need anymore. I payd just the standard shipping 20 GBP for 2, plus 19% German VAT & some clearance service (similar to UK costs). I just want to cover my costs, If somebody wants them drop me a PM.
    I will than breakdown the exact costs (for me they are in EUR)
    but again I don't want profit out of it, just fair cost coverage.
    Best regards
    Plamen
