A long time ago or as far as I remember, there was a contest that you held in the #aseanhive community.about small boats,If I'm not mistaken, at that time the contest was for boats made of plastic or made of paper or from book sheets.and as far as I remember, the participants were from Aceh who took part in the contest, one of us who won was from Aceh.but for now the contest or the boat is made of wood,It is indeed difficult to distinguish the colors of the small boats that you release.maybe if you check it or color it a different color.perhaps it is even easier to recognize the smaller boats.if the boat gets stuck.or if the boat stops for a moment on the river bank, if its color is bright, we will definitely know its whereabouts.
