The engine is accommodated in the vessel body. The jet propulsion unit is driven by the engine and propels the vessel body. The weight information obtaining processor obtains weight information regarding a weight of the vessel body. The engine controller controls an engine rotational speed such that a vessel velocity reaches a predetermined set velocity. The target rotational speed determining processor determines a target engine rotational speed corresponding to the set velocity in accordance with the weight information. The engine controller controls the engine rotational speed such that the vessel velocity reaches the set velocity based on the target engine rotational speed determined in accordance with the weight information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Jet propulsion watercraft and control method thereof","description":"A jet propulsion watercraft includes a vessel body, an engine, a jet propulsion unit, a weight information obtaining processor, an engine controller, and a target rotational speed determining processo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9760091","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
