Description
Claims (5)
- 運転者が船体の後部に設けられたステップ台に乗った状態で、操舵ハンドル等の操作部を操作するように構成された小型ジェット推進艇であって、
前記ステップ台における前記船体の左右両側に対応する部分に前記ステップ台より上方に延びる側壁部が形成され、その両側壁部の少なくとも一方の側壁部の内部にエンジンの排気口から船外に排気される排気ガスを通過させるためのウォーターロック装置が配置されていることを特徴とする小型ジェット推進艇。 - 前記ウォーターロック装置における前記排気ガスの流れの下流側に接続される排気管が、前記ウォーターロック装置の前端部から一旦前方に延びたのちに上方から後方に向って曲がって延び、前記側壁部内における前記ウォーターロック装置の上方を通過し、さらに、ステップ台の下方に向って延びている請求項1に記載の小型ジェット推進艇。
- 前記両側壁部の内部にそれぞれウォーターロック装置を設けるとともに、両ウォーターロック装置を前記ステップ台の下方に配置された接続管で接続した請求項1または2に記載の小型ジェット推進艇。
- 前記接続管を、船体の前後方向に並んで設けられた複数の管で構成した請求項3に記載の小型ジェット推進艇。
- 前記両ウォーターロック装置における前記接続管が接続された部分よりも下方の部分を、細管で接続した請求項3または4のうちのいずれか一つに記載の小型ジェット推進艇。
