Do you mean, will foil at a lower wind speed than a windsurfer will plane? Above a certain wind speed (probably 10knots, based on the star-board...
so the pivot point remains constant which gives you a longer righting arm, basically you get the boat weight and a small increase in arm length....
2) and 4) are the same with a windsurfer, 3) I assume you mean that due to the lean the normal force of the foil is to windward. So you are...
It appeared in the last vendee globe that a significant proportion of the boats had something coming close to a wheel house. Of course it would...
Sorry if this is a stupid question, but how is Veal Heal different from the windward lean on a windsurfer when the windward chine on the board is...
Thank you for taking the time to answer, that is a great history lesson.
So true, for what different reasons whould they differ between a power cat a sailing cat?
Thanks, I can see that rounded nacelles would give rise to a slapping, what strikes me with the large power cats is that they use a very sharp...
I'd be interested to know why this sort of design is not seen on cruising/racing cats, you could potentially regain more volume in the interior -...
From a thread over at SA, stubled on this Flickr page http://www.flickr.com/photos/andamanseaclub/3245564861/ Nice looking bi-rig 'Happy Feet'
I imagine that would work well if you could control the interaction between the sails and not end up loosing too much efficiency. It doesn't sound...
That sounds interesting, I assume you are using fixed wings? do you have any thought on how to reef the rig? Are you going to the triplane to keep...
Have to say I like the idea of two high aspect ratio wings and looking at it in that form. Put a couple of free standing rotating rigs up and you...
Nice find, especially as these go up to 48 degrees. {EDIT} Ah although they are testing a different parameter, e.g. they are letting the foils...
I would assume that this is only true when the relative distance between the wings is fixed and the stagger varied and for low alpha? The...
I agree the more I think about it the more versitile it becomes. Possibly the biggest down side being having to trim both sails, so potentially...
I'm starting to think that you would mostly rig just one of the masts, the exception would be DDW and sailing close to windward. I could see on a...
That is my understanding as well, at high alpha you get a reduced interaction by placing the top wing forwards. Fortunately for a biplane the...
You have the interesting problem that the effective stagger is against you as well.
