That looks very good Rob, how did you make it, or is that a secret? Maybe two female moulds joined together with hinges all along either the...
Although it was a slight deviation from the rest of my career, for a couple of years I was involved in the design and building of large sailing...
Tom Speer has already answered this for you by saying "The shape for minimum drag for a given volume depends on the Reynolds number (speed...
Nice rendering and lots of detail, at least for the external 'skin'. I wonder if the shrouds are swept a bit far aft? and will the spreader...
I rather feel that the secondhand value of a one-off home designed and home made yacht is likely to be so low that one might as well forget about...
showing bridgedeck cuddy rolled forward to allow standing at wheel e.g. for manouvering in harbour
showing bridgedeck cuddy covering steering position, e.g. for watchkeeping at sea in inclement weather.
I think it's not unreasonable to ask why large sailing yachts are not often designed with bilge keels, which I think is basically what the OP was...
I have now completed a small rowing boat and last week we completed a maiden voyage which was an approximately 60 mile camping trip down the river...
Interesting thread, best wishes for your new project. I am also interested in possibilities to use foils in a 'foil assist' mode. Just a few...
Purely diagramatic - hull and foil case shown translucent
I agree that your design is looking much better now - the deep void you had below the bridgdeck was an obvious waste of space and resulted in...
If you have a Google account I think I am right in saying that all your movements while you have your phone with you, assuming that it is at least...
Do you have any dependable measurement data for 'a rig with a rotating wingmast and fully battened sail'? - if you have I would be most interested...
Its my understanding that in the context of aerofoils the term 'efficiency' is usually taken to be synonymous with 'lift to drag ratio'. Perhaps...
Manfred - no I hadn't seen the two threads you mention so thankyou for the links. I have now taken a look at the two threads. The first one...
I think it is possible. I am assuming that by 'efficiency' they mean lift to drag ratio. If you do an internet search for 'forces on sails' or...
On our small monohull we have the centreboard, when down, angled aft about 15 degrees whereas the rudder blade is angled slightly forward to...
Good idea, but those lower shrouds are generally combined with a 'baby stay' forward of the mast, would that be a problem on your boat?
