Developed for one of my clients, we have incorporated a number of features usually only found in much larger yachts. As an example a full beam owner’s suite with separate foyer that includes not only a coffee station but an owner’s washer and dryer. There is a five guest cabin layout plus convertible owner’s office that create a sixth cabin. This includes 4 cabins on the lower deck, 2 queen cabins and 2 with double single lower berths, all include generous ensuite heads with large showers. Another large yacht feature, there is a direct service corridor from the lower crew’s quarters to the guest cabins and from the upper crew area to the master cabin, allowing for full service of guest and owners cabins without intruding into areas that are in use.

The crew’s quarters are excellent, in this configuration there are 3 crew cabins all with ensuite heads and showers for a maximum of 6 crew, 5 crew should be more then adequate for this vessel. The captain’s cabin is located down 9 steps just forward of the bridge on a separate deck from the lower crew cabins. There is an option to change the owner’s office/ sixth stateroom to a captain’s cabin directly behind the wheel house.

The vessel has been designed to maximize the use of out door entertainment and relaxing spaces. There is a generous boat deck that can carry up to a 24’ tender plus additional water toys. The walk down transom provides easy water and tender access and is deep enough to be fitted out with a fighting chair. There is direct access from the swim platform to the Lazarette. The swim steps lead up to the aft deck dinning area which incorporates a table for 10 guests and has steps that lead up to the boat deck and then up to the flybridge deck. The flybridge is a true entertaining/lounging deck with another large dinning table for 10, full bar, optional Jacuzzi and space for deck chairs.

The heart and sole of the vessel is the engine room, where there has been no compromise in keeping the vessel to her heritage. All equipment is selected for reliability and ease of service, the arrangement and structure being pulled directly from the proven world cruising vessels that INACE YACHTS has built.
