115' Denison 1988

The ’Legendry’ THUNDERBALL.

“THUNDERBALL” set the benchmark of speed and innovative design among American Muscle boats.

Powered by 2 x MTU 16V-396-TB-94 Triple turbo engines delivering 3500HP each linked with ZF Gear boxes to ROLLS ROYCE KA-ME-WA Jet drives. She immediately set industry records for speed and endurance. She has proved herself as an exhilarating fast boat on the plane, achieving 50+ knots and a solid passage-maker in heavy seas when run for maximum cruising autonomy.

Originally, the ROLLS ROYCE propulsion and engine package alone was a $2.4 million upgrade from the standard, which translates to a huge value/speed to a buyer in today's economy. Her shallow draft and vast salon space make her an ideal live aboard, Charter vessel or as originally conceived Fast Cruiser.

Commissioned from the renowned Denison Yard, Fort Lauderdale in 1987 by John Rosatti to successfully compete against his speed nemesis John Stallupi, still aficionados of fastcraft. She is still: TheFastest Twin-Engine Motor Yacht over 100' built in the US in the 20th Century! The innovative design concept has been mimicked by others but never bettered.

The current BritishOwner has had a long affinity for ROLLS ROYCE, which was his motivation to be part of the THUNDERBALL history. He has done the hardest work, which is bringing the powerful and innovative ROLLS ROYCE engineered MTU 396-TB-94 Series (3,500 HP x2) Diesels and the ROLLS ROYCE KA-ME-WA Jet Drives up to full working order and refining them for the modern cruising environment. She has recently had extensive engineering reports and assessments including a full sonic hull thickness testing following sand blast to bare metal below the waterline. 

Thunderball has recently completed several extended offshore passages and has cruised the Mediterranean. The Owner has seen her potential achieving speeds approaching 40 knots. He and his wife have enjoyed spending summers on the “Costa Blanca” coastline and the beautiful “Balearic Islands”, Spain.

The very attractive pricing allows the New Owner room to tackle the interior refit, and tailor The  Fastest Twin-Engine Motor Yacht over 100' built in the US in the 20th Century to their cruising needs.

I amprivileged to be selected as the Exclusive Listing Agent for my favourite DENISON (Other than our family, of course!).



Presently THUNDERBALL is berthed in Denia, Spain where I met the Owner and his Captain, John. (who also runs an experienced team of Refit Engineers, and would be keen to support the New Owner), 

THUNDERBALL is ideally located either for transportation back to America or as a central base to explore the beautiful European, Mediterranean coastline. The Captain / Engineer has extensive knowledge of the boat, history, works completed and required to prepare THUNDERBALL for the approaching season.


THUNDERBALL’S full beam interior provides vast interior accommodation on all 3 deck levels. Her style, lines and speed make her a stunning yacht. An exceptional 118’ / 35mtr yacht.

Her full hull width accommodation achieves a vast MAIN SALOON (32’ / 10mtrs long x 21’ / 6mtrs wide) and MASTER SUITE. Exceptionally large widow area gives unmatched space, views and light. 

All this translates to an ideal yacht for entertaining and exceptionally spacious living. During her successful years in BVI charter she frequently accommodated parties of 45 with a license to max 60 people.

Whether the boat is used as a Live Aboard, Meeting Venue, Charter Boat or for Family Holidays the space is unmatched on boats of this size.
