    I'd be more concerned about putting that much weight up high in the boat
    and probably offset to one side. Aside from the weight, the movement at
    that level in rough seas could be substantial. Be sure to tie them down
    securely lest you have catapulting batteries in the saloon.

    adequate
    ventilation or do I need a special blower and overboard discharge?

    Good choice in batteries!

    Since you are using the Northstar batteries then you can get away with
    it.
    However you insurance company might be happier if you connect the vent
    tubes
    on each battery to a collector which lead outside. The Northstar battery
    is
    one of the few with a built in vent cpllector tube for external venting.

    The second aspect of battery ventilation is the removal of heat created
    during charging.
    With 2000 amp hours capacity you can easily drive these with 500 amps
    and
    more if you are careful and use temp compensation.

    Most likely your charging source will not be that big, so heat buildup
    is
    not going to be a big problem.
    You won't need a blower unless your insurance company insist on it
    because
    they haven't caught up with the technology.

    Regards
