Sunreef Yachts has revealed details and renders of its new 40M Explorer model, designed to take its owners further off the beaten track.

The Polish boatbuilder says that with slimmer, more efficient hulls, the new 40M Explorer takes less energy to propel at speed through the water. This is aided by Sunreef’s light composite build and a state-of-the-art electric powertrain.

Sunreef’s proprietary solar skin is designed to convert every external surface of the yacht’s hull and superstructure into a power source, generating enough power to run every system on board, from the air con and the icemakers to the jacuzzi and the audiovisual equipment.

A large bathing platform aft transforms into a beach club for lounging, a watersports launchpad or a dive shop, depending on requirements. Fold-down wings broaden the platform to run around the corner of the boat.

Four large bright guest cabins fill the main deck, while the upper deck is largely devoted to the owner’s suite. This creates a secluded oasis. which is connected to the owner’s private terrace by sliding doors.


By slicing into the water ahead of the yacht, the bows are designed to take the sting out of the incoming waves. This makes for a more comfortable onboard experience by reducing pitching and lessening the energy needed to propel the yacht.

The bows are a key part of the Sunreef Explorer Eco’s transatlantic capability, along with the twin 540-kW motors and their 10-knot cruising speed.

The 40M Sunreef Explorer Eco can comfortably accommodate 10 guests and is supported by seven crew members.

Explorer and Sunreef ambassador Mike Horn has helped to inspire the design of the new yacht in a growing collaboration with the brand.

Sunreef Yachts’ chief executive Francis Lapp recently joined him in Greenland as part of his “What’s Left” sailing expedition.

“Exploring Greenland under sail with Mike has served as a profound source of motivation for me to continue to act for a sustainable future within the yachting industry,” says Lapp.
