If anyone is after a new tfoil set up, I’m looking in to getting a new batch of bulbs made out of stainless or titanium.
Martyn and I have made foils, we can offer you the 4 moulds for the foil that has been on poppy for a year and a bit, or I can offer to make you a set (will be made when I am able to and will probably cost you materials and a beer)
The bulb cost drops a lot depending on how many they make. To make a rudder and a horizontal cost me about £400 in 2020 (it spend a year sat on my shelf)
The design challenge was to make a competitive foil set up that would allow for easy transport and flexibility in foil design. As you can see from the photos the rudder consists of one vertical foil, a connecting bulb and a horizontal foil. Martyn conducted some CFD on our design in solid works and produced the model for the moulds.
This means both the horizontal and the vertical foil can be swapped out depending on the conditions/crew weight/design and development. (We have a big, medium and small horizontal set in the works)
Equally, there is a work around for you if you don’t want a new vertical rudder blade that would fit this bulb/horizontal.
If you’re interested, let me know.
