I distrust fast pins where rig tension is low, boats with slack rigs and such like. I have a couple and decided to use them on my dyneema lowers for ease of adjustment, and I decided they were less critical than on the shrouds or forestay so it would be a safe place try them out. I had a protracted capsize on Sunday and during the process of recovering one of the fast pins came partially out releasing the lower and preventing me from sailing on. I'll be reverting to clevis pins and keyrings this weekend.

@Graeme, if you’re having fast pin failures then they’re not seated properly, or the tiny spring behind the tiny ball bearing retainer isn’t working, allowing the pin to creep out. Anything with moving parts needs maintenance, especially if it’s exposed to salt water.

iGRF @2.49.
I take it back; you have obviously been a statistical outlier.

Here this is the sort of thing I would have liked to see applied to those shrouds, ignore the fact the illustration is on shoes in this video, the Boa system has been used on lots of applications from Snowboard boots to wind and kite harnesses, as a use for micro adjustment on the fly it would work on shrouds.

However on this point.
If you have had a mast fall down five or six times, statistically compared to other dinghy sailors that would point overwhelmingly to operator error on your part. 


Well it's been over two or three different boats, the EPS came down on the lake when a fastpin twisted out of one side of the chain plate, have still got the bent out of shape chain plate to prove it.

The Farr 1st time was a shackle that came suppled brand new, nothing I did. 2nd time might have been a bit my fault not saying why, third time was another fast pin on the lee side (I was out on the wire we all went in the water together)

The Hybrid/Fireblade was a fast pin (why do I never learn)1st time, then a bottle screw but I managed to get ashore before it completely fell down.

I've had boats that nothing (like the mast falling down) went wrong, the Musto, L3K, RS500, Alto, RS100, and the Solution, Solo, Minisprint have all been OK.

iGRF should move onto model yachting. Maybe the 36" box rule class. Loads of room for innovation there. 3D printed model yachts are a thing now.

Having said that some of the 3D wave sails they built, I still rate to this day as superior to anything that has arrived since, but they were assembled from 3 D panels over special formers, so there wasn't the single continual strand sandwiched between the mylar or whatever carrier film they applied at the time.

It's still a very black art what makes sails fast over what you actually think is going to do it.

Seriously, hardware has improved dramatically in my sailing lifetime, a lot of credit must go to Harken who have reliable kit that can out live a boat, and typically are sold in packs to the builders.  Buying blocks and cleats to improve systems was a regular Saturday activity in the 70's, but since then this is a rare occurrence.

Modern spliceable line is a gift to the boat bimbler who has nothing left to do on a Saturday, and offers the opportunity to junk large quantities of line, when you realise that the newly fitted continuous system is 20mm too short ... at least the dogs now get fancy leads.

Mylar and CAD technology has transformed sails.  Dacron sails only held their shape for a few races, and sailmakers struggled to replicate a fast sail back in the day, now I can by a mylar sail that is fast for two or three seasons, and is exactly the same cut as the National Champions.

But my award for contribution to hardware goes to improved rudder stock technology, particularly Mr Winders carbon rudder stocks ... gone are the days of sketchy downwind legs where controlling ones direction was a somewhat random event.

In by opinion soft shackles, thimbles and dog bones are a solution looking for a problem, though I was recently excited to find such a problem requiring a solution on my Solo inhaul system ... though there is more friction than the block it replaces I now have a system that incorporates a thimble, dog bone and soft shackle ... at least it used up some of that expensive Dyneema lying in the garage
Happily living in the past

Coming back to the original question...
Ball bearing blocks made a big impact when they became affordable.
Here is a bizarre one, combination trolley/trailers!
Not really hardware, but modern ropes and also clothing. 
The transition from wooden to FRP was painful. Timber, the original exotic material,  was and is still competitive when combined with the right design and build method. FRP was initially largely very poor in most cases, no durability (in terms of stiffness) but now much improved with newer sandwich construction and understanding of the lay of directional fibres. 
I reckon that takes us to the 2000's. Since then it has been tinkering at the edges and the introduction of carbon in rigs/structures for the few that can justify the cost. 
If you look at other industries then that is were the development starts, particularly with materials, but the biggest changes there have been in process control and quality. 
I guess the next development is a production 3d printed complete boat!
