The 21.7m Spirit P70 is designed for fuel-efficient cruising over long distances

Spirit Yachts launches P70 modern classic motor yacht

Nigel Stuart


Spirit Yachts has launched its largest modern classic motor yacht, the Spirit P70, outside its waterside yard in Ipswich, Suffolk.  The P70 was designed by Spirit Yachts for an experienced motor yacht customer who requested an owner-driven yacht capable of cruising 1,000nm at an average of 18 knots across the North Sea without having to refuel.  As with all Spirit yachts, the P70 has been completely customised to suit the owner’s itinerary and criteria.

Spirit Yachts managing director Nigel Stuart commented, “The launch of the P70 is a significant milestone in Spirit Yachts’ history.  Whilst the core business remains sailing yachts, we are seeing increasing demand for motor yachts tailored to suit an owner’s cruising plans.  We are responding to that demand with innovation and expertise devoted to the power range.  Spirit Yachts is renowned for elegant design, build quality and engineering expertise; with the launch of the P70 the company has proven it can successfully deliver world-class motor yachts alongside its portfolio of sailing yachts.”

With regards to the design of the yacht, Spirit Yachts founder and chief designer Sean McMillan explained: “The owner will keep the P70 in the UK and cruise to the Baltic in the summer, so the yacht had to be capable of undertaking long passages in comfort but aesthetically stay true to Spirit’s timeless style and classical elegance.  He liked the design of our existing power boats, so we combined the flared bow and tumblehome stern from the P40 with the 1930s-style of our sailing yachts and applied it to a larger motor yacht design.  We added deep bulwarks to allow guests to move around the decks safely, particularly when underway out at sea.”

Constructed using Sapele ring frames to which Douglas fir longitudinal strips were bonded, the P70 build followed the same core processes of Spirit’s sailing yacht hulls.  Once the initial structure was complete, diagonal layers of kaya wood planking were laid down, sanded and vacuum infused with a thin layer of epoxy resin.  This lightweight method of construction means that at 24 tonnes (light) the P70 is almost half the weight of its GRP counterparts.  Twin MAN i6 800hp engines will generate a cruising speed of 18 knots and a maximum of 25 knots.

Nigel Stuart added: “The owner is very knowledgeable when it comes to motor yacht engineering and he was keen to keep noise and maintenance to a minimum.  He requested Seatorque oil-filled BOSS shafts, which are mounted to the hull structure using low noise fittings.  The connection to the propulsion engine is flexible in order to reduce shaft-line noise and vibrations.  The yacht has an easy-access, spacious engine room and a lithium-ion battery bank in the stern that will power the air conditioning and Sleipner curved fin stabilisers overnight without having to run the generator.”

On the top deck of the P70 is a flybridge with two double Stidd helm seats and additional seating for six guests.  A hydraulic operated 750kg crane is included for up to a 3.7m rib.

Nigel Stuart continued, “The owner also had very specific criteria when it came to an interior layout tailored for his guests.  The master cabin is at a separate end of the boat to the guest accommodation and the dining saloon is open plan next to the galley as there will be no crew onboard.”

The wheelhouse sits midships on the main deck and has double and single Stidd seats located in front of the navigational equipment and engine controls.  An additional raised sofa is to port, with a chart table and stowage to starboard.  A few steps down and forward of the wheelhouse is the main saloon, complete with a ‘rise and fall’ TV, a bar and panoramic views from the forward windows.

The lower deck houses the accommodation and living area.  Stairs from the main saloon lead down to a forward ensuite owner’s cabin, complete with a bath, and an ensuite single cabin, which doubles up as an office.

A separate stair case down from the wheelhouse provides access to a single day head and the open plan dining saloon and galley.  The saloon dining table has a U-shaped port side sofa, with additional seating to starboard, wine storage and a TV.  The well-equipped galley includes an American style fridge-freezer with built in ice-maker, below floor chest fridge, dishwasher, twin sinks, four burner induction hob, a fan oven and a microwave.  Aft of the dining area are two twin guest cabins, which share a head and shower.

Spirit Yachts is currently building a P40 superyacht tender and will begin construction on a P48 cruising yacht this autumn.  The P70 will remain at Spirit Yachts this autumn for ongoing interior work before being handed over to her owner.
