Castoldi’s low-lifting arrangement receives Lloyd’s Register approval
Waterjet propulsion systems and yacht tender manufacturer, Castoldi, has announced its Jet Tender 19 RB SOLAS has recently received Lloyd’s Register certification for a new low-lifting arrangement. This engineering certification enables storage in substantially reduced-height superyacht garages.
Giacomo Castoldi says: “The new Lloyd’s Register certification validates our innovative low lifting arrangement, opening new installation possibilities for superyacht owners without compromising safety or regulatory compliance.”
According to Castoldi, the Jet Tender 19 RB SOLAS was the first SOLAS-compliant tender on the market to feature an inflatable system for self-righting capability integrated into a dedicated stern peak. This proprietary technology is the company’s patented R.I.S.E.R. system.
“When we first entered the SOLAS rescue tender market, all tenders were stored in open-air areas on superyachts over 500GT, so the length of certified lifting straps wasn’t a critical factor,” explains Castoldi.
“SOLAS rescue tenders must be [able to be] launched within five minutes and lifted using multiple lifting points because they must be handled fully loaded with 5+1 people onboard (five passengers plus one person on a stretcher).
“In recent years, we’ve observed a changing trend: superyachts increasingly prefer to store SOLAS rescue tenders in enclosed garages, often alongside their main tenders, for aesthetic and space-optimisation reasons.
“In response to this market evolution, we’ve redesigned the lifting arrangement of our SOLAS tenders to enable garage storage while maintaining full regulatory compliance. This presented significant engineering challenges due to limited onboard space, the need to accommodate 5+1 people with freedom of movement, various safety equipment, and the requirement to maintain proper stability. Additionally, garage cranes are typically very low, requiring us to find the right compromise between lifting point positioning and operational clearance. SOLAS tenders must also pass rigorous certification tests, including drops from 3-metre heights and lateral/frontal impact assessments.”
Castoldi’s new Jet Tender 17 went into production in May 2025.
Powered by Castoldi’s waterjet drive matched to a 230mhp diesel engine and built with a deep-V Kevlar composite hull, this tender also incorporates a patented self-righting system R.I.SE.R. Unlike conventional SOLAS-compliant vessels utilising external arch structures, the R.I.SE.R. mechanism is integrated within a dedicated stern compartment and can be activated during capsizing events via an actuation lever mounted below the swim platform.
