Why not use duplex 2205 or 2507 stainless steel as supplied by Sandvik, Outokumpu. Many benefits including easy fabrication, lead moulded in keel...
The formula board has just one person aboard, just like a Moth, but seems to have 44% more sail area. Which is more efficient?? How would a...
Just to be clear, it was John Ilett who originally developed the wand arrangement for the Moth, incuding the 90 degrees offset, later copied by...
Further discussion Hello Earl, Here is a link to a previous discussion in this forum on this topic;...
Unbalanced boats Try a J24 for starters, they appear well behaved initially due to the balanced rudder, but this belies an unbalanced hull which...
Just to clarify a few points: The directional instability I refer to can occur under power in either direction whenever the boat moves forward,...
I have noticed that modern yacht designs tend to have the keel well forward and in some cases the centres of effort, bouyancy and lateral plane...
I use a one piece foil Tee foil with the shaft embedded 20% back from the leading edge. This is close enough to the centre of lift to have small...
I think there are more problems than just the engineering. If the wand provides complete foil control, then it must be set up with an excellent...
Sorry to dissapoint you, but one specific advantage of the fully articulated foil is that it will not be possible to "jump" the boat. My aim was...
So why not use a fully articulated main lifting foil?
To explain the need for high bow up attitude, I think you have to keep in mind that the Moth dinghy foiler has made a real breakthrough in low...
Berthold is correct! Semi-circular, least wetted surface sections will give the lowest resistance. The main reason this is not used in Moths is...
This is not really a problem, but probably only because the boat is so small. When tacking in displacement mode you can roll your weight aft, this...
