Bullitt

28m Sailing Yacht | Wally 93

A 28m Wally 93 campaigner engineered with a high-performance four-tank ballast system, capable of transferring tonnes of water in under six seconds.

The Brief

Bullitt’s refit called for turning a ballast system concept design into a workable system: four tank volumes with fully automated pick-up, transfer and discharge, integrated into the yacht’s existing general arrangement.

The Approach

BMComposites worked alongside Pure Design & Engineering, Judel/Vrolijk and Innovative Structural Design to complete the final design layout for the system. All composite components were built at the company’s own facility, with 3D scanning, 3D printing and CAD/CAM CNC manufacturing used to produce ultra-lightweight CFRP parts.

The scoop intake required particular care, filling the tank volumes through a controlled master pump and distributing water to suit the chosen trim. At the critical moment, several tonnes of water transfer to the opposite tank in under six seconds, a process capable of placing significant load on the new and surrounding structure without precise design and installation.

The Result

BMComposites worked closely with the captain, designers, engineers and subcontractors to manage the project from initial briefing through installation and final commissioning.

In her first outing after the refit, Bullitt won IRC 1 at the 2023 Rolex Middle Sea Race and took overall victory on corrected time.
