The 80m yacht is a project by Oliver Stacey Design in collaboration with BMT Nigel Gee. The yacht features a simple, low-aspect sail plant with three identical wing masts in combination with matched in-boom furling mainsails.

Norse, an 80m sail-assisted exploration yacht, is a design concept presented by Oliver Stacey Design in collaboration with BMT Nigel Gee.

Coming together to present a fresh interpretation of the explorer vessel genre, the two companies have developed a concept designed for maximum self-sustainability, global range and minimal environmental impact.

“When we were initially looking for a conceptual thread for the design, I had recently seen the Viking Voyagers exhibition at the National Maritime Museum in Falmouth”, explains designer Oliver Stacey.

“The extensive range and endurance of the longboat. The adventuring spirit of the Vikings. The use of sail as a secondary power source. These are the inspirational reference points which led to the development of Project Norse.”

Sail assisted hybrid propulsion

Norse is designed around a sail assisted hybrid propulsion system. “We thought long and hard about hybrid, and how such a system might help us achieve our goals for the project,” says James Roy, yacht design director at BMT Nigel Gee.

“Despite outward appearances, this is not a sailing yacht; at a time when hybrid is a buzz word in our industry, we couldn’t move away from the unmistakable truth that sail assistance is the ultimate hybrid,” he explains, adding that the final configuration makes use of a hybrid diesel electric / diesel mechanical (CODAE / CODOE) with sail assist.

This configuration has been chosen because it maximises reliability and flexibility, while requiring minimum crew effort in deployment, operation and recovery.

It is anticipated that the sail-assist mode will be utilised for the majority of the yacht’s passage making and that, under optimum conditions, power can be regenerated through the trailing shaft-lines to battery storage.

With a profile inspired by the longboat, Norse features a long and robust keel flat with shallow draft. In addition, she has been designed for a high degree of manoeuvrability to provide the vessel the capacity to access secluded anchorages normally considered off-limits to a yacht of 80m.

Norse is set to carry a robust gantry crane for reliable launching and recovery of a wide range of vehicles including a seaplane of up to 12m wingspan.

The tender garage has also been designed to deploy an array of support vessels and adventure vehicles including a landing craft, ATV, submarine and snow mobiles.

In line with the vessel’s long-range and extended self-sustainability, Norse is built to Ice Class 1d and complies with Category C requirements of the Polar Code.

Allowing operation in light ice conditions, this capability permits summer operation in the Polar Regions for specific routes of interest, including the Antarctic Peninsula, Arctic Svalbard and Greenland.

Despite its explorative purpose, internally Norse offers a social living environment with an informal layout; the owner lives close to family members and guests, who share large open-plan spaces. Smaller intimate spaces provide privacy and quiet when required.
