DOVETAIL, Contract #446, is the third to the last Trumpy built and the last of the desired houseboats. Commissioned by Mr. Earl Cantor, she was originally named GERIFAY and was used as a committee boat in the 1974 America’s Cup off Newport, RI. Later names, in correct order, include: LADY Q, HILLARY JANE, CARONIA, ZARYA, STATELY LADY, DISCOVERY and finally DOVETAIL. Her present owner has continued the first-rate custodianship of this very fortunate yacht. Those inspecting her will find her in excellent mechanical and cosmetic condition, with fresh hull paint, completely updated systems and basically wanting for nothing but a new owner’s personal touches.

DOVETAIL features John Trumpy's most desirable “galley-up” arrangement plan. Wheelhouse forward, followed by a full beam galley (with pass-through to the salon), large salon with separate “day-head”, and an aft deck that can be open to the breeze or enclosed and climate controlled. Crew area is forward on the lower level followed by the engine room, two identical twin cabins with en-suite heads, and finally a full beam owner’s cabin updated to include a centerline queen berth.

Her generous 18’ beam, on deck day head, and large crew quarters make her very comfortable for entertaining or extended cruising. The present owner has capitalized over $1m in improvements alone during last three years to ensure she is as sound and reliable as possible. She shows very well and those who inspect her will find that she does not disappoint. Almost all 2017/2018/2019 refit work was done by the experts at McMillan Yachts, Inc. in Portsmouth, RI.
