164’ (50m) Custom Trinity IMPROMPTU Now Asking $19,500,000

Northrop & Johnson is pleased to announce a $1.4 million price reduction on the 2011 custom Trinity motor yacht IMPROMPTU, now offered for sale at $19,500,000. IMPROMPTU is represented by yacht brokers Kevin Merrigan and Kristen Klein. After significant refits, a successful 15-year ABS survey completed in 2025, and a stellar charter history, she is primed for adventures with her next owner.

Her most notable upgrade came during a 2022 refit, which included a full exterior paint job, state-of-the-art A/V and WiFi upgrades, and more. She has also undergone a full mechanical refit, including a 10,000-hour main engine service and a 2,000-hour generator service.

The yacht’s Patrick Knowles interior is warm and welcoming. The open-plan main salon offers generous seating and dining for 12 guests, anchored by a centrally located spiral staircase with a dedicated wine cellar at the top. The skylounge is designed for entertainment, featuring an L-shaped sofa, a full bar with seating, a 60-inch TV, and a games table. The bridge deck aft is ideal for alfresco dining with a circular table for 12.

IMPROMPTU accommodates 12 guests in six staterooms. The split-level on-deck master stateroom features a king-size bed, a private elevated lounge with 180-degree views, his-and-hers en-suite bathrooms, and a private study with desk at the entrance. A VIP stateroom on the bridge deck is surrounded by large windows, while the lower deck hosts three king staterooms and a twin stateroom with a Pullman berth.

IMPROMPTU’s entertainment capabilities are highlighted by her expansive sundeck. The focal point is a custom raised waterfall Jacuzzi for 12 guests, complete with intricate tilework and dual entry steps. This space also includes a large outdoor bar with seating for five, a barbecue, a dayhead, and a large dining table for alfresco meals, surrounded by forward and aft chaise loungers, an oversized sunpad, and built-in seating areas designed for relaxation and socializing. With tender garage and bow tender storage, all guest areas remain dedicated solely to guest use.
