What's a 1957 Morris Oxford? What I was driving at (geddit) was that I think you'll find your average Freddie sailor isn't as beardie as you might have thought... |

These days the average Freddie sailor is a 19 year old slightly hungover student. Much as it was when I was a 19 year old slightly hungover student... These days, I'm a beardie. |

Looking at the available info Bethwaite and partners seem to have been building Kevlar Tasars in 1975, but abandoned it in favour of glass around 1977. The same records don't make a claim to be the first to have used kevlar. http://www.tasar.org/technical/kevlar_tasar.html and http://www.tasar.org/technical/Tasarstart.html Kevlar seems to have been invented in 1965, http://www2.dupont.com/Kevlar/en_US/index.html First commercial exploitation maybe very early 70s.

At the time Kevlar was being punted about as the next miracle fibre to
replace glassfibre, I seem to recall it had been used in the Military, bullet proof vests, I think it was also a constituent part of chobham armour but again, it was hearsay of the time. Back then, what was going on 'down under' we wouldn't have been aware of, the M25 had yet to be built and mobile phones didn't exist never mind internet, most of this sort of intel was word of mouth. How we got involved, we were trying to develop a small powerboat that would pull a water skier around a fifty mile course in under an hour using only a 50hp motor, and came across a boat design from a Guy calle Bo Oldenburg, this thread prompted me to look him up, he lodged his patent in the US office around the same time, but he'd already had succesful trials of his stepped hull and chined design. Patent pdf We bought a GRP version, then with the help of a guy called David Harper, we went up to Bolton or Burnley, somewhere oop North and not far from the Dupont facility and one of their reps suggested using this new cloth they'd just released.. Anyway the rest is as described, it didn't wet out well with either Polystyrene or Epoxy resin fell in half and sank we had to revert back to GRP, (Epoxy then wasn't like the stuff now, there was a place on IOW that I got involved with much later, 79-80 building hollow epoxy aluminium honeycomb sailboards, but that's another story.) The other thing, Kevlar wasn't at all stiff, it's strength was more, impact resistant, that G10 stuff is about the best application that uses it in fibre form. I remember as the boat moved off the sides flexed, but it was light and ultimately it did go fast and we achieved 48 mph with a skier prior to that best speeds were sub 45 mph. Edited by G.R.F. |

Don't worry you're not to old, as Peter and Dawn Langdon have proved and also incidentally so has Mike Arnold, legendary Firefly sailor and the man who designed the Alto! |

If it doesn't break it's too heavy; if it does it wasn't built right
