    I was recently asked the what people did in the old day to keep stuff from growing on their boats. So my question is what did they do long time ago
    for anti fouling ?

    So before that boats must have been beached and scraped , then maybe cover with pine tar or the like . They must have been in a constant state of rebuild.

    Later they used line seed oil mixed with poisons like antimony and cyanide. That worked very well, it even kept the other boats clean in a harbor.

    Ram's fat melted and painted on the bottoms. Also, tar.

    "Whitebottom" was lime and tallow and used in the eastern US. I believe this is what was traditional on Arabic Dhows too.
    UK fishing vessels were tarred on the bottom with pitch in the seams.
    A recurrent act there was "breaming" where flame was used to burn off marine growth and soften the tar and pitch, enabling a pitch mop to be run over the surface and smooth it up.
    And here's Wiki's reference on bottom treatments.
