Boat Details

Description

INNISFAIL, Contract #242, is one of the few remaining Mathis-Trumpy fantail yachts built. Commissioned by Joseph M. Cudahy of Illinois for US East Coast cruising, she was the second Mathis Trumpy he had commissioned. Built as INNISFAIL, she was later named YP-354 in 1942 by the US Navy as she was commandeered for service during World War II. During her time with the Navy, she had two 20mm cannons mounted on her decks and a depth charge rack on her stern. She served her country in this manner for 5 years before being refit in 1947 by the US Government. She continued to serve the US Government and was utilized by US Presidents, foreign dignitaries, and heads of state until 1965, at which point she returned to private ownership. A comprehensive 2007 refit restored her original name. She has been well cared for inside and out and holds a current USCG Inspected Vessel Certificate for 65 Passengers.

Broker Remarks

INNISFAIL is unquestionably one of the most significant and recognizable classic American yachts presently offered for sale and represents an exceptionally rare opportunity to acquire a true piece of yachting history. A highly desirable, larger pre-war Trumpy, she is beautifully maintained, thoughtfully updated, and well-equipped for both private enjoyment and respectful commercial use. Her timeless lines, graceful proportions, and expansive crew accommodations provide a level of comfort and practicality seldom found in yachts of her era.

Commissioned in 1939, INNISFAIL has enjoyed a remarkable and storied history, having hosted numerous United States Presidents (Roosevelt, Truman, Eisenhower, Kennedy, Nixon, Ford, Reagan, and Clinton), foreign dignitaries, and heads of state throughout her lifetime. During World War II, she proudly served the United States Navy as patrol vessel YP-345, outfitted with twin 20mm cannons on deck and depth charge racks mounted aft. Her survival through wartime service and the many chapters of her distinguished career only further solidify her standing as one of the truly iconic surviving American motor yachts.

The current owners have proven to be exceptional stewards, cruising her extensively from the Florida Keys to Nantucket while maintaining her to a very high standard. Although operated solely as a private yacht, the owners have elected to preserve her USCG Inspected Passenger Vessel certification for up to 65 passengers, a designation requiring rigorous annual and biennial inspections and surveys.

INNISFAIL presents exceptionally well throughout, and discerning buyers who step aboard will immediately appreciate the pedigree, craftsmanship, and extraordinary level of care she represents. Few yachts afloat today can offer such a compelling combination of provenance, capability, and enduring elegance.
