About this tender
The 9.9m platform in the Castoldi Jet Tender range is the upper end of the single-engine waterjet line, the build that sits between the mid-range JTs and the twin-engine JT34. At 9.9m length and 3.0m beam, sixteen on the CE plate and 700 litres of fuel, this is a tender designed to handle the longer shore runs that 80m-plus owner programmes generate.
What this size of Castoldi gives you is range. The 700-litre tank moves the conversation from coastal hopping to a real two-hour transit reserve at cruise, which matters when the mothership is anchored further offshore than the closest beach. Diesel waterjet, single Yanmar package, sixteen-guest plate, this is the build we recommend when an owner wants the JT range character on a hull big enough to feel like a yacht rather than a tender.
Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
Above the JT27 and below the twin-engine JT34, the 9.9m sits at the top of the single-engine Castoldi range. Sixteen on the CE Cat C plate, 3.0m beam, GRP composite hull. The standard Castoldi tube and folding console package transfers up to this size.
700 litres is the headline. That is roughly twice the JT27 tank capacity and gives the boat a usable two-hour reserve at cruise speed, which is what makes the platform credible as a primary tender for offshore-anchored programmes rather than just a beach run boat.
9.9m by 3.0m is sized to fit the dedicated tender garages on hulls in the 75-110m bracket, where the design budget allows for a stand-alone owner tender of this size. Castoldi's lift point scheme transfers up to this hull on the same engineering basis as the smaller boats.
