Take a look inside Heesen's 51m superyacht Irisha

Dutch yacht builder Heesen has launched 51 metre Irisha, which sea trialed in May, 2018. Now newly released photos give a more detailed look into the interior design and exterior details of this fully custom superyacht, created by Harrison Eidsgaard.

Irisha was originally envisioned as a day boat to cruise in Sardinia, Italy. As such, she has excellent outdoor living areas, including the expansive sun deck, pictured above. The radar arch provides protection for the sundeck bar, while white canvas gives shade over an al fresco seating area. The superyacht's hot tub is surrounded by sunpads for comfortable lounging.

When the Compass tender is taken out of the aft beach club and the stern door folds down, this creates a further entertaining space directly on the sea. A sauna and massage area is found here, and white curtains reminiscent of Nikki Beach give a relaxing vibe.

Extensive use of glass is a standout feature of Irisha's exterior styling. The superyacht has a sleek look, much in thanks to her glass-wrapped superstructure and a design layout that puts the bridge on a half deck between the main and sundeck.

The glass over the helm is also one of the largest pieces of chemically hardened compound curve glass ever to be made in Europe.

The bridge and sundeck are linked by a large sliding glass door and drop-down window. In this way, not only is glass used as a stunning exterior design feature, but as a means of opening up the superyacht to the outside and creating the feeling of being on the bridge of a sports boat.

Irisha has a spacious main deck master suite that opens onto a French balcony. This balcony isn't of the fold-down variety, but is fixed in place, meaning that it's always accessible to her owners and doesn't require the help of crew to use.

A press of a button allows the full-length glass doors to slide back, revealing the outdoor space of this cosy French balcony that is all at once open to the fresh sea air, yet protected as well. It's the ideal place to enjoy a morning coffee, curl up and read or have a nightcap before bed.

An undoubtable wow-factor on board the Heesen yacht Irisha is the stunning staircase. This open oval staircase extends through three decks of the yacht.

According to Heesen, besides the impressive use of exterior glass, this was the most challenging feature of the build. The yard's in-house interior joinery firm also constructed the interior.

This sinuous staircase belies its aluminium structure, which is masked by a polished, hand-plaster technique created by DKT Artworks and topped in tempered glass structural balustrades and a leather handrail. It is truly a work of art in itself.

Harrison Eidsgaard is known its unusual general superyacht layouts, and it proves its prowess with Irisha. The main deck arrangement is unusual indeed, with a main deck aft cockpit that doubles as a winter garden and outdoor living room. This space can be air conditioned or heated to be used in all weather.

This aft lounge is connected to the large dining room by sliding glass doors. _Irisha's _dining room table can extend to seat up to 22 guests. Not only is this a stunning interior space, but it seamlessly connects to the aft lounge via the doors.
