IMPROMPTU, the 2011 custom Trinity, is a timeless yacht with endless exterior spaces and stunning interior designs penned by Patrick Knowles. Her 2022 refit included a complete exterior paint job, extensive A/V and WIFI upgrade, a new ASEA shore power converter and a new sewage treatment plant. She is in exceptional condition after completing her ten-year ABS survey in 2020. IMPROMPTU’s successful charter history is a testament to her seaworthy build, plethora of amenities and impressive guest accommodations. 

The Trinity’s open-plan main salon features a generous seating and dining area for 12 guests. A beautiful, centrally located spiral staircase houses a dedicated wine cellar at the top of the stairs. Aft of the main deck is a raised conversation area with plenty of seating and air conditioning. A dual staircase leads down from the main deck aft to a large swim platform and tender/toy garage. The yacht’s skylounge is centered around guest entertainment featuring an L-shaped sofa to port, an impressive bar with seating, a 60-inch TV and a games table. The bridge deck aft welcomes guests to dine alfresco around the circular dining table for 12. Further aft is a nice seating area to gather after a meal. IMPROMPTU’s galley is on the main deck to port and features an open, U-shaped design. 

IMPROMPTU’s six stunning staterooms welcome 12 guests. Her configuration is versatile, with a split-level master stateroom featuring a king-size bed and a unique elevated lounge with 180-degree views and his-and-hers en-suites. There is also a private study at the entrance with a desk. On the bridge deck is a VIP stateroom surrounded by large windows. On the lower deck are three king staterooms and a twin cabin with a Pullman, all accompanied by desk areas and shower en-suites. Nine crewmembers are welcome in a Captain’s cabin and three bunk cabins. 

The luxury yacht’s stunning sundeck is the ideal place for guests to gather together. The centerpiece of this impressive area is her custom, raised waterfall Jacuzzi for 12, with intricate tilework and steps to enter from both sides. The space also showcases a large outdoor bar with seating for five, a barbeque and a dayhead. The large dining table encourages alfresco dining under the stars. Forward and aft chaise loungers flank the perimeter of the sundeck, along with an oversized sunpad and built-in seating areas.
