Interesting thread. There are many talented people who build their own boat having had no formal training - but that does not mean that boat...
But have you found anyone to design it first?:rolleyes: If this is a genuine project, I, for one, would love to be kept up-to-date on this...
Thanks Anton, there is some useful stuff there. However, most of the articles seem to be written by SP, hence the slight bias about SAN foams....
I am looking to build a 4.3m (14ft) sailing boat of moderately high performance. It will be sailed mostly on lakes, with the occasional outing on...
Thanks Jam. As I understand it the flow between the jib and main, in 'the slot', is slowed down so that the air flow on the leeward side of the...
Apologies if this has been covered previously, but I have a question. Why is the positive effect of the main on the jib greater than the...
Thanks for all the help. One file works fin on 'smooth and slower' - another still has problems around the chine. I'll work on customising the...
Thanks Martijn. I hadn't realised they were flat panels, the result is remarkably good (visually). Which file format would you recommend for...
Thanks Mike, I'll give that a go. The other format I tried impoting with was 'waveform', which gives a really good copy of the hull, but no-one...
First off, apologies. This question will be a bit unclear because I'm not at the right computer at the moment so don't have access to Freeship or...
Please note - I like the concept of the wingsail/ wingdrive, I just want to clear up any technical quibbles.
Did you actually read the paper I posted the link to? This shows, quite clearly, that an asymmetric foil (a sail) produces more lift than a...
I haven't read all of this thread in detail, but it seems that RHough is getting some unfair stick. A thick foil does not produce more lift than...
I know this is a really dumb question - but how do you display the diagonals in FREE!ship? The icon is always faded out so that it can't be...
The above notes only refer to the sailing ability of the boat. If the asymmetric hulls allow for more accomodation, this may be an over riding...
Asymmetric hulls only work if the windward hull is flying (or at least, is more out of the water than the leeward one). If the boat is dead flat,...
Mr Speer is bang on, but if you want a simpler to understand explanation (but still correct) visit arvelgentry.com and look at the magazine...
This is surely the best free software available anywhere, for any purpose. Thanks for all your effort Martijn.
Thanks - is that just the carbon or the carbon/epoxy compound?
Doug, Congrats on bringing your idea to fruition! Does the mast top device allow you to bend the mast whilst retaining a full height jib?...
