Wouter, <br>I would prefer to see as few restrictions as possible.. <br>Max length, max width then either max mast height, or max luff length.. or possibly max sail area.. allow single or multiple crews but if one nominates as a single (or double) the regatta must be sailed as that.. <br>as for genacker. just rate the max luff length.. <br> <br>I believe the 100 kg min is too high.. Firstly you wish a High Tech class then you suggest it should heavy enough to encourage be lowish tech construction.. Seems a tad od.. Perhaps the class should be F16 MT where M is moderate .. <br> <br>If someone wishes to build a nomex carbon hull with M18 style rig then I would suggest its what we should allow.. <br>What about a solid wing mast with a genacker? It would be HT surely.. Would this be legal?<br><br>
