Alexander McDiarmid Design Studios
Thirty years ago, in the summer of 1992, the legendary Destriero crossed the Atlantic in record time
securing the Blue Riband.
This historic event and the legendary yacht that performed this impressive act form the basis for a
groundbreaking concept which captures Destriero’s unbeaten record. We don’t intend to replicate
such a record breaking yacht, but rather honour the engineering prowess, long range capability and
sustainable high speed of the original. Based on an extrapolated version of the Ghost G250 platform,
we looked into the possibilities for a more efficient high-speed propulsion solution combined with
increased levels of circularity and sustainability.
The GWP-345:
“The GWP is the concept that we simply had to do.
We explored the limits of what’s possible with today’s technology and construction methods without
sacrificing comfort and practicality.”

A profile like no other:
Continuing our long collaboration with Ghost Yachts resulting in a waive piercer project giving a
refined yet restrained, powerful overall exterior design with a very distinct and modern style shown
in her profile. The project sets itself apart from the start with the hard chine V, wave piercing hull and
reverse bow as used on the flagship Ghost Yachts G250, 80m project. The lightweight, low-drag
aluminium hull with carbon fibre reinforced superstructure offers fuel efficiency and high top-speed
while maintaining crisp handling and stability.
Design Thinking – Less, but better – Weniger, aber besser
A very original project that adheres to legendary Industrial Designer Dieter Rams’ ‘Ten Principles for
Good Design’ giving a very distinct and modern style shown in her profile, ‘hauntingly’ beautiful yacht
design.
The GWP-345 is the sum of all her parts created by talented individuals who are first and foremost
passionate about yacht design. Design excellence starts from the completely rethought and very
Owner adaptable General Arrangement/GA layout and advanced hull naval architecture all packaged
and beautifully styled from stem to stern. The exterior styling is inspired by the military aesthetic of
modern naval frigate and warship designs as seen in the superstructure, simplified into angled
surfaces while emphasising the yachts striking yet balanced proportions.
The single level guest area:
The logic of the single level guest area sees the five/5 VIP guest cabins and one/1 Owners full beam
suite all situated on the main deck. Twelve/12 guests in total are situated from midships to foredeck.
The Owner and Guests enjoy easy access and circulation throughout the entire main deck. The
central focus is the saloon with port and starboard, full height glazing, aft running the full length into
the midships dining area.
Housed within part of this glazing, guests will be able to see the structure of the yacht and air intakes
from the aft saloon area as the ventilation shafts descend into the Engine Room. Technical ‘art’
construction exposed.
The master dining area enjoys port and starboard balconies for the ultimate dining experience with a
potential, different view, morning, noon and night.
A swimming pool aft on the maindeck is directly above the beach club, while the wellness area and
spa, cinema and gym are located in the hull from aft to midships.
The sundeck with jacuzzi and bar is accessible by three stairways and is protected by a
motorised/large, semi rigid sun canopy.
The sunken and hidden foredeck featuring a flush deck motorised canopy for a shaded exterior
lounge with the two 10m tenders are situated within the foredeck, accessible by hidden knuckle
crane.
The Heliport is also located on the foredeck.
We work closely with Jonathan Turner and his team at Maritime Aviation for best practice.
