At the moment, Bray Yacht Design is working on a new model test program as a continuation of their ongoing advanced hull technology development. The first stage of the new program has concentrated on an enhanced bow bulb form tested to 20 knots. Reductions in fuel criteria for this hull as well as appendage form represent a radically reduced carbon footprint.

For 15 years the studio has been doing R&D into fuel efficient hull forms and appendages. Generally, their vessel designs are 30% more fuel efficient than most; this new technology has pushed those boundaries even further.
Bray Yacht Design‘s new bow bulb produced an added 25% reduction in powering requirements. This translates into real-time savings: 25% less fuel consumption to achieve the same speed, 25% smaller engines, and 25% less fuel tankage for the same range. Not only does this help to reduce build costs, it also has a very dramatic impact on operating expense. The added bonus is larger interior space for accommodation as requirements for both tankage and mechanical spaces are smaller.
The next phase of testing is focused on new appendage technology: so far this indicates a further 15% savings. The test tank has told the studio that the present form is the most efficient that they have seen to date, and when completed this new work will place the Bray Yacht Design’s hull designs far beyond any other technology available today.
