Boat Tail

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

Sweptail proved the department; three patrons set its next brief.

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.

HICON BID

Buying interest, silently.

A HICON Bid is a confidential expression of buying interest on the Rolls-Royce Boat Tail file — never public, never shown to other members. It is not a binding purchase, and HICONIUM holds no funds.

You keep one? The record starts in your garage — identity, papers, photography, and the market evidence this file already carries, bound to your chassis.

What moves the price

Two F40s can be indistinguishable in a photograph and a million apart at the hammer: the difference is never in the paint. Build the file below and watch the band move.

Spans are indicative, drawn from the documented sales cited beside each attribute. The calibrated multipliers — and how they compound for one specific chassis — are member instruments.
