  "description": "都市の水辺・艇庫背景に配置する、独自の小型サドル式ウォータークラフト。V形の船底と成形デッキ、実際に低くなった左右の足元溝と滑り止め、長い成形サドルと支持部、立上がり舵軸・ハンドル、無表示の計器面、後部乗込みステップ、開口した噴射ノズル外形と船底グリルを造形。一式1点で、ボートの縮小版や色違いではありません。 最下点をY=0とする水平中央原点です。水面の高さ・喫水位置は配置側で選んでください。水・人物・物理挙動・操縦・浮力・流体力学・救助機能は含まず、静的外形のみです。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）1.196 × 1.085 × 3.205 m、8,130三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A compact original saddle-style personal watercraft for urban waterfront and boathouse scenes. Its V-bottom body and molded deck form two genuinely lowered foot channels with grip strips. A long shaped saddle/support, raised steering stem and handlebars, blank instrument face, attached rear boarding step, open jet-nozzle exterior and underside grille complete the distinct assembly. It is one model, not a resized or recolored open boat. The horizontally centered origin places the lowest geometry point at Y=0; choose the waterline and immersion height in your own scene. No water, people, physics, driving, flotation, hydrodynamics or rescue functionality is included: this is a static exterior assembly. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.196 × 1.085 × 3.205 m; 8,130 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
