Reliable cheap engines a long time ago. Electric lights. Self draining cockpits. Fibreglass hull. Aluminium masts. Winches Dacron sails GPS. that is only 8. I love my modern sailboat (all except the engine which I prefer to leave home) olewill
Marinas and their fees!
Insurance companies that dictate what you can do and where you can moor.
Rich pr*cks in motor boats that contravene their ASBOs (plumbers?).
Modern AWB yachts with so much windage they can't stay in a channel if there's a cross-wind.
Recorded music at 100W with cockpit speakers.
Starter boats always over 30 ft.
Training schools that go out in a F11.
The end of cheap diesel (taking "sailing" in it's broadest sense as a moboer)
The H&S wonks who insist on taking the hoses away in marinas (sorry - that's trivial)
It surprises me that GRP only came 50th since its invention made boats cheaper to manufacture and allowed the big advances in design. The material has also made it far quicker to repair any damage and easier to maintain. Most of us would not be able to afford to sail if it hadn't been for the invention of the material.
I cannot understand how GPS is not number 1. IMO all other things mentioned sort of refine something that can already be done another way, all be it maybe not as cheaply or efficiently.
GPS provides an accurate fix of your position in all weathers. Its unbelievable...
I haven't seen the originla list, but from the reations of some of the people on here I wonder where 'electronic echo sounders' came in the list.
Some of us (golly I am showing my age) remember when the first whirly light echo sounders started to be produced at a reasonable price. The one we had on the boat I sailed at the times showed feet and fathoms and you had to twiddle the gain to get a reliable echo. It was a wonderful thing that soon showed you where the edge of the dredged channel was.
I therefore nominate affordable "Echo Sounders" as one of the fifty devices that have changed yachting.
Of course I forgot, now that people seem to drive their boats round the screen on their plotter, some people seem to manage to without an echo sounder and log...
