FOILING MINI 6.50
The 650PRO was the first Mini 6.50 to achieve stable foiling.
We used our full set of design methods from structural design, foiling simulations, CFD simulations to develop a new foiling arrangement for the 650 class made of semi submerged V foils which can be retracted on each side and a long gantry supporting the aft foil.
The structure has been the subject of advanced research from our side, and with the input from the client the Alfred Wegener Insitute, leading to a new type of structural arrangement. An arrangement that we use today on our designs and used on board Ineos Britannia’s racing yachts.
The 650PRO attracted wide public attention:
– countless views and press coverage in 25 countries
– nominated for the Foiling Awards
– the project required the Class Rules to be changed, and this opened the door for future foiling boats in the Mini 6.50
The 650PRO was built and tested succesfully by his builder and remains what it was designed for, an incredibly advanced one off machine.
‘ The 650PRO was a fantastic project. We had a lot of resources and perhaps I should have pushed to keep the design simpler for the boat to work economically in the class.
The brief of the client was for a very advanced boat and so we did! We use many of the technology on board our designs and the America’s Cup today’

THE 650PRO IN KEY POINTS
SIMPLE
With is surface piercing main foil and single elevator, the TT 650 PRO is a simple foiling platform that require no electrical control system.
EARLY TAKE OFF
The main foil exits from under the hull and extends to the rule maximum beam to maximize efficiency so you can benefit from foiling in more conditions.

STABLE FOILING PLATFORM
The elevator is mounted on a gantry to increase the power of the elevator. The elevator has been generously sized to provide greater pitch stability, the faster you go, the less elevator angle is needed.
RETRACTABLE
The main foil can be fully retracted when the sea and wind conditions are not favorable for foiling. The foil can be stored up on deck and to windward for better weight placement.
SCOW HULL SHAPE
The hull has been specifically designed for foiling, including an area aligned with the foil whose role is to smooth out some of the wave motion for a more constant foiling height. The beam is carried almost the full length to maximize both form stability and planning area, enabling high speed sailing when weather conditions make foiling impossible.
RIG ARRANGEMENT
A rotating regular mast tube and mainsail is fitted, with an aero fairing at the intersection of the sail and the tube for increase aero performance. In addition, the standard traveller arrangement is replaced by a reverse vang designed specifically for this boat which provides an 80:1 mechanical advantage. It carries the mainsail leech tension and thus reduces mainsheet loads, which makes for easy dynamic mainsail trimming.
