Three cars, three patrons
Boat Tail is a three-car Coachbuild series, not a production convertible with special trim. Each patron received the same hand-formed body idea and a different commission; identity and factory archive define the asset.

Empty ledger by design: a reported build cost is not a public transaction, and no attributable resale result was located.
Overview
After Sweptail, three clients independently responded to a proposal for a modern Boat Tail. They agreed to one common body form, then developed separate materials, colours and hosting details with Rolls-Royce over four years.
The first commission used rich blue paint, Caleidolegno across the aft deck and two reversible BOVET timepieces that could serve as wristwatches or dashboard clocks. Its restored 1932 Rolls-Royce Boat Tail provided a direct reference point.
Rolls-Royce completed three cars. The company has not disclosed their invoices, and no attributable example has appeared at public auction.
