SOLD 1958 15’ Twin-Cockpit Cadillac Seville & Tee Nee Trailer

1958 15’ Twin-Cockpit Cadillac Seville Offered at $24,500: 1958 15’ Twin-Cockpit Cadillac Seville & Tee Nee Trailer

While lesser wood and aluminum Cadillac Marine & Boat Company examples from the fifties have survived, I can find no other molded plywood, twin cockpit Model M Caddy Sevilles in any condition, let alone one preserved to museum quality.

With a wholesale price was $1,245 in 1958, precious few were ordered. The GM Heritage Collection does not have one.

Hull number M 5883, may be a one-of-a-kind. She is without doubt an incredibly fine example of cross-fertilization between the period’s auto design and emerging fiberclassics-to-be in the waning years of wooden boats.

No expense was spared during our comprehensive, three-year cosmetic and mechanical restoration of the boat, engine and trailer.

  • Molded plywood hull stripped and refinished inside and out;
  • New upholstery matching original Evinrude blue;
  • Mahogany and Avodire decks and covering boards stripped, refastened and coated with 10 coats of Interlux Two-Part Perfection;
  • Original Special Edition 1958 Evinrude (30 HP) outboard completely disassembled, rebuilt mechanically;
  • 1959 Tee Nee tilting trailer with 1958 NOS baby moons and Cooper white wall tires. Every part was disassembled, sandblasted, repainted chrome yellow and reassembled; and
  • Hardware restoration by Mickey Dupuis, D&S Custom Plating in Holyoke, MA.


Watch the Caddy emerging from Snake Mountain Boatworks in May.

If you bleed Caddy, here is a unique opportunity to add something to your collection that no other enthusiast or collector can duplicate!
