Centreboards must have been earlier and certainly a step change

Centre boards would have made boats lighter, that would help with speed, are they better than a keel though for pointing and reaching?

Can't help thinking there have been step changes ever since the first person figured out that if you hollowed out a log to get across the river it was much better than just sitting astride one with your legs dangling for the alligators...

Even if looking at the last 100 years or more, kicking straps are a good thing, but not the first, or the best, but certainly part of a great package. Hollow masts, spreaders, lowers, sail cloth advances, Cumninghame, loose footed sails, bendy masts (we shall pass by bendy booms), battens, roaches with control, just to scratch the surface.

Glued plywood followed by composites, made for notable reductions in weight and increases in stiffness

Giving a score out of one hundred, Sail technology got to be in the nineties.
Hull materials probably eighties.
Foiling latest.

^ The interesting aspect of this is the symbiotic relationship of the developments, if hulls had not moved on from clinker or carvel construction than planing as we know it today would not have been possible, let alone foiling.

The step change in hull technology from the 40's through 50's then 60's was massive.  The step from cotton to terylene was also massive. But I think that the returns have been diminishing ever since then.  And I am not sure that many changes since the 70's have massively improved the enjoyment or accessibility of the sport.

You could argue that changes in clothing technology has transformed the sport since the 60's, I am not sure that the two hour race I did yesterday in chill winds would have been a lot of fun in Dunlop Magisters, jeans and a wooly jumper (nor the heavy jacket that I wore as a 14 year old in a Laser).  The development of high performance sailing clothing has enabled us stay on the water in comfort for many hours, facilitating the present open meeting and championship formats.

Certainly second that observation.

Clothing, good point, I have sailed in minus 6 only ears and hands cold.
Simple performance boats similar to 'Enterprise' seem to hold their ground, next step could be a very light version with structural integrity, ie, Hull fittings don't fall out.
