I never said "all boats....".actually the opposite, I have continued to point out how people generalize too much. There are those who have "museum piece" boats, which they keep "historically correct" (or at least their interpretation), kept shiny and pretty (and run for cover when anything over 10kts kicks up)....they take them to boat shows sailing on sunny days. My boat was designed 75 years ago, but is not a "museum piece"...the building process included techniques that didn't exist when it was designed (which were improved on later on). The boat was designed as carvel plank, but was built as strip plank, glued and covered with fiberglass (later replaced with fiberglass using epoxy resin), there was alot of lamination and fiberglass work in the construction....not "historically correct". AS well as rig tweaks that differ from the designer's original plan.
I guess most people don't realise technology goes both ways:
Most visitors do not notice, but of the large list, a few inventions "historically correct museum piece" boats have benefited from include:
* Plastic ropes (looks like hemp but isn't - but lasts 100 times longer in the sun)
* "Canvas look" terylene sails (lasts longer than Egyptian Cotton): A tiny aside here is that I know of only two Tall Ships world-wide using traditional sailcloth and neither of those travel the world.. Go ahead, prove me wrong
* Dyneema rigging (looks like gal wire but is heaps stronger, lighter and easier to maintain)
* Modern paints, glues and varnishes..
..and there are 'old' things once forgotten being rediscovered by the new breed of yacht designers - including square-cut mainsails, bowsprits, plumb bows and the importance of hull balance..
