Sailrocket is a serious contender in the race to break the outright world speed sailing record, which is currently over 50 knots. Chris Hornzee-Jones is the designer of its unique wing sail. Aerotrope engineers carried out configuration design, aerodynamic and structural engineering studies to optimally match the wingsail to the boat.
The main innovation of Sailrocket's concept is the way in which the sail and keel elements are positioned so that there is virtually no overturning moment and no net vertical lift.
When used correctly this concept results in a boat which no longer has obvious stability limits and in which the only significant response to gusts is an increase in speed!
