Title:
JET PROPULSION BOAT
Document Type and Number:
Japanese Patent JP2015085841
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a jet propulsion boat capable of achieving not only the stabilization of hull behavior during deceleration but also rapid deceleration.SOLUTION: A jet propulsion boat includes a hull, a jet propulsion mechanism, a bucket, and a control unit. The control unit controls a driving force by which the jet propulsion mechanism moves the hull forward. The bucket can be moved to a retreat position which is separated from jet flows jetted from the jet propulsion mechanism, and also to a receiving position where the jet flows jetted from the jet propulsion mechanism are received. While a driving force P is raised to a second driving force P2 after the bucket moves from the retreat position to the receiving position, a rise rate of the driving force P can be changed according to a forward speed S.
