Oh dear which bit of your thread did I misread then? Parkers are not all bad, they dominated 505 building for a period and are now trying for a come back, obviously out of your pocket range, if you're scrabbling around for old second hand junk, but others might find the new parker interesting, I know I did.

Interesting question re what exotics to avoid. The new Parker has a carbon Kevlar option. I personally would avoid any Kevlar in the hull laminate. It does little useful in a race boat hull. Its stiffness is not that good and it is completely useless in compression. If it ever gets exposed it will fluff up and cause problems. It absorbs moisture. The only thing it could improve is the ultimate penetraion resistance in an impact ( not really an issue in a racing dinghy). Carbon skins maybe with a bit of glass on the outside skin are the best. On core materials -a Nomex honeycomb would give the best stiffness/weight properties, but this is not without its own issues and if it is not done right will be a horror. Cross-linked PVC is a good option generally for weight and properties.

What about the new parker? For an 'old' boat I thought it looked the nuts. Have there been any results with it yet?

So what number Waterat or Krywood should I be looking for? I am happy to update the boat as I understand the hull shape has stayed the same. when was the exotic material added to the boats and is there any mix of exotics you would stay away from?

Upper mast support in not required to hold the mast up, it is to keep the mainsail looking and working correctly. As in you will go faster with than without.

Don't forget that if you are off the wire righting moment has decreased and thus the loads coming from the sail must have decreased too.

Thanks, Null. So do they have to stay on the wire initially during drops to stop the mast top snapping? Gybing must be a bit iffy too?
