Canard design In the beginning I copied the Miller meat cleaver canard, 450 x 100mm. This had lots of drag when submerged, which is not a...
I though it was simple, but here is another attempt! The fundamental relation controlling the speed of a displacement boat is its...
Given the difference in age, style, design and construction, the improvement of the open 60 does not look so big does it! ;) How about doing...
Halyard I notice that the Tornado cats run the free end of the halyard back up the track with the head of the sail, tucked beside the boltrope....
A short quote from an interesting article in a local sailing magazine - Afloat: http://www.afloat.com.au/external%20files/0504_Yesteryear.pdf...
With such a huge sail with low heeling moment and immense righting moment its no wonder that it can go fast...but is it really that efficient?
L'hydraplaneur Do you think this L'HYDRAPLANEUR will really work! Looks like tremendous drag in most conditions! My own experience says...
Tom, Firstly a long wheelbase is definitely a possible solution. I already tried a rudder foil and sensor operated bow foil with no centreboard...
Tom, I have a halyard but do not use it. We are pretty spoilt downunder with grassed rigging area beside golden sand beach. I have no cradle, rig...
Foiler Rig Hello Tom, Yes you are correct, I am trialling many things using the one test platform.The Scow Moth is not really intended to be the...
It is indeed a nice reference of amazing ideas. Unfortunately many are impractical for round the bouys course racing which is what I am trying to...
Actually, this is the first time I have seen this photo posted myself:-)...
I notice in the April 2004 edition of the Australian Sailing magazine an article on steering trifoil canting keel designs. It mentions the use...
Hello John, The main part of the calculation is based on sail costs vs fuel costs. I agree with you that the engine etc are not constructed of...
Assuming you want to carry a certain load at some average speed, (unstated) then a sailing vessel will need a mast, rigging, keel, ballast,...
Hello Tom, Perhaps we could take the calculations of resistance for a Moth foiler a little further. It is becoming more critical now for us to...
It is necessary to have a light displacement and high power to weight ratio to get things going, so I think foils can only be effectively applied...
Tom, Many thanks for your response, I am still digesting the implications.... Firstly though I note that the total drag is actually quite low...
Here is a question for Tom Speer, as I think he can help us a lot to understand foil types and configurations we can use on Moth foilers....
Tom, I think this is a pretty good summary of the situation!. Miller has found in practice that the surface tracking canard sensor works...
