From New York
to Singapore
on One Tank
Spearheading a new wave in 21st century yachting, The Spearhead 118 is decidedly different. She combines the rugged go-anywhere qualities of an explorer yacht with clean sharp exterior styling and sophisticated understated beauty rooted in Scandinavian design.
Article:The history about Spearhead 118
A modern high tech carbon fibre motor yacht, she presents a low profile and the design sensibilities of a sailing yacht. Pioneering a new concept in yacht design, construction, and technology, she touts extremely low fuel consumption and has unrivalled range of 12,000nm at a low cruising speed. However, she is no slow poke, at sprint speed— when an impending storm or perhaps a medical emergency necessitates,—she rises to the occasion with a max speed of 22 knots!
Solar Panels and Hybrid propulsion
The Spearhead 118’s canopy is roofed with 100 m2 of solar panels, enabling the yacht to produce just under 20 kWh— enough to cover daily energy needs at anchor, including AC. The ample solar energy can also power its diesel/ electric hybrid propulsion system at a low cruising speed of 4 knots. The yacht functions well on electric or on diesel alone or via a combination of both. Each time diesel is used, the battery banks are recharged. In addition, they are further charged by the boat’s solar panels. In this way, emissions are reduced up to 90%, compared to other same size traditional motor yachts.

The Dream Team
Builder/founder of North Sea Yachts, John Lundin, is a Swedish national with a yacht yard and commercial shipyard in Indonesia. Naval architect, Dennis Harjamaa, based in New Zealand, has worked at McMullen & Wing, building yachts entirely out of carbon fibre with extremely lightweight hulls. Andreas Martin-Löf is a leading Nordic architect and designer who has recently created some of the most innovative and award-winning interiors in yachts built at yards such as Baltic Yachts in Finland and at Moonen Shipyard in the Netherlands.

Technologically sound
Following Dennis Harjamaa’s drawings and specifications, hydrodynamic experts Profjord AB, based in Gothenburg, conducted computational fluid dynamics (CFD) simulations to assist the team with resistance calculations, ensuring the boat had the right propulsion and hull design. They also analyzed the seaworthiness of the boat in challenging sea conditions and applied ‘ISO22834 – Comfort Assessment on a Large Yacht’, which assesses comfort on board with and without stabilizers. Spearhead 118 is built to be self- righting in any sea and weather conditions.

SOLAS approved SAR tender
A safety-rated lifeboat /rescue RIB ( rated by the International convention on Maritime search and rescue) lives aboard Spearhead 118. This for the 6m diesel-powered tender— extremely large for the size of it mothership— can carry all Spearhead’s passengers and crew aboard at one time. It is the perfect vehicle for exploring diverse destinations when Spearhead 118 is at anchor. In accordance with SOLAS, the International Convention for the Safety of Life at Sea, this tender doubles as lifeboat. Moreover, it is easily deployed from the yacht and ready to for action in no time flat.
Upshot
The Spearhead 118, built by North Sea Yachts, offers the ‘now’ generation a fundamental change from the ordinary. The yacht’s refreshing design and tried- and- true technology offers an alternative to superyachts burdened by an abuse of fossil fuels. Clients for Spearhead 118 are those individuals who seek to drastically and genuinely reduce their carbon footprints on our world’s oceans. The Spearhead 118 is in the vanguard of a greener yachting experience.
