Must be something with my Dell laptop. Running Internet Explorer also. When I try it on my Mac, there is no trouble. On the Dell I get redirected to a Robotics search page (?!?!?) Thanks and sorry.

Sorry for crossposting from the F16 forum. Thought it might be interesting here:

For those interested, we just pulled the first strip plank hull half off the mould and did a quick weight calculation.
I stepped on to our bathroom scales and got my base weight. I then picked up the hull half and we found the difference. Came out at 7.7Kgs. There are obviously several problems with this method to find the weight, but that is what we have got for now. Hull half is glassed on just one side with regular weave 200gsm glass but will now be sanded and glassed on the inside with 163gsm twill weave. We have learnt a lot from the process, so we fully expect the next half to be finished a lot faster with a better result.

So, if we say the finished hull half will weight in at 8.5Kgs that puts on a target weight of 26.5Kgs for the complete hull according to Marcus. Target should be 24Kgs to be close to min. weight, and I think we can achieve that. Phill and others have come up with some tips to further reduce weight which I dont think have been tried in other boats yet.
Even with just one side glassed, the part was very stiff. It will be extremely interesting to see how this project turnes out or if we will have a huge pile of firewood once we sheet in.

The peel test. No we have not done that yet. We wanted to get the inside glassed before we trimmed the stern to fit. We have stripped the next hull half while testing different ways to sand the inside smooth enough for glassing. Looks like a foam pad with velcro glued to a rubber disc is the best option (as Phill said all the time). Will know more about it tomorrow night as that is a building night.
