I know that this has been posted in the past, however, I am not finding it with the search engine. I am looking for the link to the site to calculate the Texel/provisional portsmouth number for catamarans.



Specifiaclly I am looking to find the provisional number for the new 3D-20 that Vectorworks Marine is building. The first boat is due to be launched this summer, depending on the delivery of the rig that randy Smyth is designing.



Any help finding this link would be appreciated,



Thanks

Matt
