Rupert, skis have changed shape a lot in the last 40 years, which luckily for learners has made them much easier to use. They work in a completely different manner and just rely on a bit of speed and getting the edges engage to make smooth fast turns.

Do you think ski jumpers complain that their kit, despite changing from wood to composite, shape being tweaked, fittings being much more hi tech, complain that "they look like they did in the 50s". Where are the rocket boots, why can't we use squirrel suits, etc etc.

Or is it just certain ex windsurfing dinghy sailors?

Like a lot of technology the improvements depend on using them correctly. 

Soft attach is only so useful when the hull isn't fitted out with sharp deck eyes. The picture in the advert possible doesn't show them in their best utilisation.  

But, pretty much anything within a system (like cascade) will all be soft attach on my boats. And if I can get a kind attachment point then soft attachment in my experience allows the block to align better with loads. It also gives you a bit more freedom to position the block the correct distance from a fitting where that is important (no need to stack shackles up).

Low friction rings I love. But again, have to choose when to use them. I have replaced all the little blocks in the control line take up with them. They have slightly more friction (under low loads) than bb block, but who cares in a take up, it's not me pulling it, it's elastic. Plus on the sea the maintenance of those tiny blocks was a hassle. Friction rings are less maintenance, cheap and lighter. 

Within a control system low friction blocks only really become helpful once you exceed the working limit of ball bearing blocks. Below that I think most people would still prefer a smooth ball bearing sheave.  So I don't actually use many LF rings on the 800 within systems because the loads aren't that high.  I also have allen's extreme high load block which is a hybrid ball bearing (for loader loads) and plain bearing ( which kicks in at higher loads) which protects the bearing from damage. 

I have replaced pretty much all bowline knots with soft shackles. It used to do my head in getting the spinnaker tack and halyard the exact distance from the mast / pole. But now I make a soft shackle the correct length and it's always spot on (and stronger, but strength of line isn't usually an issue on dinghies). 

The other place I like soft shackles is on the 2:1 halyard. It reduces friction slightly over a regular shackle, but also holds captive around the halyard so you can't lose the shackle, and as it has no pin, you can't lose that either... I think everyone has been there once or twice before, scrabbling around hands and knees looking for a shackle or pin that was just flicked out of your hand by a flog of a sail.

Here we go, I learned to sail in a shoebox int gutter.. Now I've got a single handed version of a 1950's style boat with a few bits of modern string to pull H2 ffs.

That was state of the ark art in 1955, and what we were doing on a budget in 1975. By the end of the 70s, you could buy ball bearing blocks and cleats. By 1990, Merlins had fully raking rigs. It all works better these days because of dyneema etc, in the mid 80s you could get un-spliceable kevlar at at high cost.Of course many boats were fitted out very cheaply even when better fittings became available. How old is the classic Harken Cam-matic cleat design? The first ones I owned were on a clapped out boat in the late 80s.  One thing which I find mildy amusing is that my Dad's Ent had turnbuckles on the shrouds in the 70s now they're either banned or an expensive upgrade on some classes?

What a gloomy bunch of old blokes - when I think back to my experience of sailing in the 80's and 90's and compare that with when I returned in the 20teens its surprising how much better / easier boats are to sail and in part that is due to better "hardware" throughout the boats we now sail.

Found a commercial Tufnol block in my spares box a few days ago, It might get used on my refit of the boat.. I've built a few Tufnol blocks as well, when I was in Saudi, marine suppliers are thin on the ground, Tufnol was cheap as were the other materials, and I had access to a very good lathe..

The sheets and halyards fitted last Saturday are of course Dyneema... Still considering whether to go for Dyneema Shrouds..

Yes I remember we had a Tufnell one on our GP14 back in 1970.IIRC it was called a Novex block-great block.
