Loy Krathong is the second most popular Thai holiday of the year, right behind the Songkran festival - the country-wide all day long water fight . . .So Loy Krathong, pronounced Loy Gratawng, is when Thai people get to make little pretty floating things out of banana leaves or whatever and place a candle on it. They then Loy (float) the Krathong (the floating thing) onto the river and there are lots of stories behind it. The above tradition has inspired us to design our Krathong watercraft with a round bottom hull. It is driven by a pair of motorised rotary paddle wheels.
