PURPOSE:To permit the compact storage form by installing the rails which extend in the longitudinal direction in the upper and lower stages at the rear edge part of the hull of a small-sized gliding boat equipped with a water jet propulsion apparatus and installing an auxiliary deck and a gliding part in slidable ways along the rails. CONSTITUTION:Rails 6 are arranged in the upper and lower stages in the longitudinal direction of a boat, at the rear edge part of the hull of a small-sized gliding boat which is equipped with a vertically turnable handle pole 2 in front and equipped with a water jet propulsion apparatus. An auxiliary deck 16 and an auxiliary gliding apparatus (ship bottom) 7 are installed so as to be pulled out from the rear edge part of the boat along the rail 6. The both members 6 and 7 are connected through a supporting member 21. The trim by the projecting deck part can be adjusted by allowing the deck part to be spread and at the same time allowing the gliding part to be pulled out. When not used, the members 6 and 7 can be accommodated into the boat body, and the compact accommodation of the boat is permitted.
