Australian VYC yardsticks have this baot at 79.5 with the Taipan uni (no spi) at 76.5 ; the two seem quite close. However Altered (with spinnaker) is racing of 71 (= also A-cat rating) and F18's of 70; to put things in perspective.

Quick Texel (2006) rating calculation suggests that the boat can be around 104/105 when fitted with a spinnaker and a F16 mainsail. If the asking price is right then it good be a good poor mans F16. It will be one of the best boats to convert to a full F16. It will never be really competitive with the newest fully optimized F16 designs but it will be rather close to them just the same. The added spinnaker will make the boat handle downwind legs in big wind better.

How much are they asking for it. As far as I know there are hardly any nacra 16's in the Netherlands, I even though none ever made it to NL. If so then you could have a good position to bring the price down alot. It is an unknown boat in NL and will have a bad resale value because of it. That will be in the advantage of the buyer.

I would check it out further.
