Design & Construction
Designed around a semi-displacement aluminium hull and superstructure she features a 8.5m beam and a 2.7m draft. The yacht is built over 3 decks with an internal volume of 490 GT (Gross Tonnes).
Construction started in late 2007. Launched in September 2010 this yacht undertook sea trials over the following months. She was delivered to her owners in October 2010.
Exterior Design
Impromptu is a 50m Trinity motor yacht built in aluminium with the long, lean profile typical of the yard’s semi-displacement series. The hull is painted white and carries a low dark window band through the main deck, while the superstructure steps back cleanly through three guest levels to the sundeck above.
The sundeck on Impromptu is the main outdoor social space. It combines a large hot tub, bar, barbecue, dining table and broad lounging areas, with enough shade to keep the deck usable through the day. The deck was also updated in 2025, with new tilework, replumbing and a new teak surround around the hot tub.
Below, the bridge deck aft takes full advantage of the yacht’s beam. With no side decks at this level, the space stretches right across the yacht and works as a sheltered outdoor dining terrace. The main deck aft is more private, with tiered seating that improves sightlines and adds separation between the guest area and the working deck aft.
At water level, Impromptu keeps guest areas clear by separating toy storage from the main leisure spaces. A tender garage and additional bow storage mean the stern remains focused on guest use rather than equipment handling.
Interior Design
The interior of Impromptu was designed by Patrick Knowles and uses dark timber, polished stone and lighter soft furnishings to create a rich but fairly traditional American yacht interior.
The main saloon uses a mix of woods and inlays, with wenge cabinetry, burr finishes and detailed joinery giving the room its character. The photo of the saloon shows this well - dark gloss joinery frames the room, while lighter carpets, cream seating and lit display shelving stop it from feeling too heavy. Forward, the formal dining space sits beyond the lounge and remains visually linked rather than shut off.
An etched glass panel separates the dining area from the central lobby and spiral staircase, keeping the space open while still giving some division between the entertaining areas and the circulation route through the yacht.
The skylounge on Impromptu has a slightly lighter feel, helped by the full-beam layout and the absence of side decks at that level. That makes the room broader and more open, with a better connection to the bridge deck aft outside.
The galley is arranged for long-range use, with strong storage capacity including a walk-in fridge and walk-in freezer, along with direct pantry access.
Accommodation
Impromptu accommodates 12 guests in six cabins.
The owner’s suite is on the main deck forward and is one of the yacht’s defining spaces. It is split level, with a king-size bed on the main deck level and a private lounge forward. There is also a study at the entrance, a walk-in wardrobe and separate his-and-hers ensuites. His includes a steam shower, while hers includes a jacuzzi bath, vanity and adjacent dressing area.
A VIP cabin sits aft on the bridge deck and carries a queen berth with ensuite shower.
The remaining guest accommodation is on the lower deck, where Impromptu has three king cabins and one twin cabin with Pullman berth. All are ensuite and fitted out to the same standard, giving the lower deck a consistent guest finish rather than a hierarchy of lesser cabins.
Crew accommodation is for nine or ten crew, depending on arrangement, including the captain’s cabin behind the bridge and a separate chief engineer’s cabin aft with direct access to the engine room.
Performance & Capabilities
Powered by twin diesel Caterpillar (3512B) 2,250hp engines, motor yacht Impromptu is capable of reaching a top speed of 20 knots, and comfortably cruises at 14 knots. With her 66,033 litre fuel tanks she has a maximum range of 3,816 nautical miles at 10 knots. She has been fitted with stabilizers to increase on-board comfort when the yacht is at anchor, particularly in rough waters. Her semi-displacement hull design means she offers a great balance of space and speed.
Amenities
A gym with all the latest equipment allows her guests to keep their workout routines while at sea. Air conditioning offers increased on-board comfort. Impromptu also features a deck jacuzzi for cooling off.
