Introducing the TF35

02/08/2019

Compared to its predecessors, the TF35 has been designed with the ambitious brief to offer top level foiling to a wider audience of sailors. With earlier take-off speeds, guaranteed foiling upwind and down and a fully automatic flight control system, the TF35 uses the latest in foiling technology, both to improve performance and simplify high speed foiling while making it easier to race.

 

THE CONCEPT

• Allow owners to have access to a high performance foiling catamaran

• Automatic flight assistance system 

• T foil and T rudder both with flaps 

• High consideration for crew safety 

• TF35 is a one design boat 

• TF35 is designed to sail on the sea and lakes 

• Easily transportable (mast in 2 parts, fit in a 40’ box) 

• Can be packed and assembled in 1-2 day 

 

 

Performance upwind: Fully foiling from 9kts TWS Upwind boat speed = 2 X TWS

 

Performance downwind: Fully foiling from 7kts TWS Downwind boat speed = 3 X TWS

FLIGHT ASSISTANCE

• Flight high and pitch are computer controlled 

• The flight assistance system generates a stable and smooth flight 

• TF35 teams can only adjust the flight height and pitch angle 

• The driver and crew members are not in charge of the flight regulation 

• The regulation software is ondesign and can’t be modified by the teams 

• Rudder differential adjustment increases the overall performance of the boat 

• Battery autonomy of 6 sailing hours

Compared to other flying boats which demand the complete concentration of helm and trim, and coordination of the crew, the TF35's automatic flight control maintains the TF35's ride height, as boat zero helm Jerome Clerc explained after the first test sail: "Yesterday was amazing. Considering it was the first time the boat has touched the water, it is a real credit to the design team how impressively easy it was to foil so quickly. We have been testing the flight control system and the foil design on a development boat, a small cat, over the last couple of months so this was an early indicator we were on the right track.

"The boat felt very stable and the plan over the coming months is to learn and develop further the flight control systems to ensure we get it just right. In stronger winds we are confident that the boat will feel secure reaching 40 knots."
