Impresively light. Paul should be sent on a road tour to pass on his magic touch with the spray gun to non-weight obsessed types who find themselves faced with a Cherub - it is very easy to add several kg's in paint

Am looking forward to seeing a used (but obviously new) boat at Ali Pali.
To aid the Pro-Grip debate.
-Any water quasi permanantly trapped under the pro-grip will be included in your all up weight as it is there when the boat is effectively "dry". It leaves the shore with you, stays with you round the course and is still there with you when you return to the shore - see the very boring debate about Saftey Kit. As it looks like your Ellway has room for a few kg's of grip/water trapped under it there is not much to worry about.
-If it helps we had significant joy with Plexus for the pro-grip. It look a serious effort to remove some when looking for the bung holes we had accidentally covered over and sets in minutes.
Phil, the boat is looking excellent and at a good weight, I know you will enjoy the unique feeling of sailing something you have built yourself.
The Pro-Grip does absorb a bit of water while sailing so there will be a slight weight penalty in sailing weight against the measured weight which should be done in a dry condition. However it is well worth it as crew rebellion is very bad for speed

I think that the water gets trapped where there are air bubbles when the Pro-Grip is applied, having a needle or sharp knife to pop the bubbles when sticking down can help.
