Well you learn something new every day!

JimC's assertion is entirely reasonable, but I never realised there was such a significant problem with the Laser hull. I thought for a moment that craiggo had misused the word (apologies). The obvious example of an assymetric hull(s) would be the Hobie 16 catamaran.

I now have a good excuse now, when I don't so well on one tack and then....... even worse on the other!

I *very* much doubt there is a significant problem. Significant as requiring different handling on opposite tacks or causing any noticeable difference in performance.

So is craiggo overplaying it? Who does knows what the variance is, if there has been all these studies that concur? Would say 5 -10 millimetres really be all that remarkable?

From memory I cant remember exactly the numbers that came up when I last saw it done, but it was small ie. less than 3mm diference in centreline to hull port/stbd.

There have always been those who claim the laser always sailed better on port but I reckon my 700 does and I think its more about our own dexterity rather than the boats.

My original point though was if you make a correction to a known fault or defect in a design and start producing them as your own, have you infringed copyright?

If it looks like a Laser it's a Laser regardless of a few mm here & there ...

If all you've done is a minor change like fairing an error in a mold, yes you would have. Same as musicians who end up paying royalties when they've copied a chord sequence from someone else's work. It doesn't have to be identical to infringe copyright.

- doesn't have to be a chord sequence ... Dick Batt's (Batt sails) brother Mike Batt was sued for infringement of copyright of Cage's 4:33.

Cage's 4:33 is that length of silence (though performed by a full orchestra), MikesBatt's piece "one minute" was 60 seconds of silence - though scored for different instruments...

Be careful out there!

I'd not heard that one! Does that mean that John Cage can sue everytime we have a minutes silence on Rememberance Sunday...
