164’ (50m) Trinity IMPROMPTU Now Asking $22,450,000

Northrop & Johnson is pleased to announce a price reduction on the 164’ (50m) motor yacht IMPROMPTU, now offered at $22,450,000 following a $1,500,000 drop. Represented by Kevin Merrigan and Kristen Klein, this custom 2011 Trinity is an excellent opportunity for buyers seeking a timeless, charter-proven superyacht.

IMPROMPTU has benefitted from a thoughtful sequence of major refits that have enhanced her systems, finishes, and mechanical integrity. In 2022, she underwent a full Awlgrip HDT exterior paint job, along with A/V and WiFi enhancements, including the installation of two Starlink systems. A new ASEA shore power converter and a modernized sewage treatment plant were also added during this period.

In 2025, IMPROMPTU successfully completed her 15-year ABS survey. This comprehensive refit included a 10,000-hour main engine service and 2,000-hour generator service.

Onboard, IMPROMPTU welcomes guests into a warm interior styled by Patrick Knowles. Her open-plan main salon features expansive seating and formal dining for 12. At the heart of the space is a striking spiral staircase crowned by a dedicated wine cellar, one of many bespoke touches. The adjacent galley, located to port, is generously laid out in a U-shaped configuration.

IMPROMPTU sleeps 12 guests across six well-appointed staterooms, with a flexible configuration ideal for families or mixed groups. Her split-level master suite forward on the main deck features a king-size bed, a private study, and a spectacular elevated lounge offering 180-degree views, along with his-and-hers en-suites. The bridge deck VIP is surrounded by windows. On the lower deck are three additional king staterooms and a twin with Pullman berth, all with desk areas and en-suite showers.

Aft of the main salon, guests are invited into a raised, air-conditioned conversation area, while dual staircases descend to a large swim platform and fully enclosed tender/toy garage. The skylounge is a vibrant gathering space complete with an L-shaped sofa, a custom bar, a 60-inch TV, and a games table. Just outside, the bridge deck aft features alfresco dining for 12.

IMPROMPTU’s sundeck is the showstopper. The centerpiece is a custom-designed waterfall Jacuzzi framed in intricate tilework. A dayhead, a large outdoor bar, a barbecue, and a full-sized alfresco dining table transform this deck into an all-day, all-evening destination. Oversized sunpads, chaise lounges, and built-in seating surround the space.
