PURPOSE: A ballast structure of a dinghy boat is provided to be firmly and stably coupled to a center board as the center board is inserted into an insertion groove of a ballast and is laterally coupled by coupling units. CONSTITUTION: A ballast structure of a dinghy boat(100) comprises a through-hole(111), a center board insertion groove(121), bolt coupling holes(122), bolts(123), and nuts(124). A ballast(120) is formed of a heavy member having a higher specific gravity than a center board(110). The through-hole is bored in the lower part of the center board. The center board insertion groove is formed on the center of the upper part of the ballast. The bolt coupling holes are formed on both sides of the upper part of the ballast and penetrates through the center board insertion groove. The bolts and nuts are used to combine the center board inserted into the center board insertion groove. |
