I tried uspn2006.csv (the US Portsmouth ratings file) on that page and while it worked, it just had a code for each boat rather than the descriptive name. Some of the codes are easy to understand (e.g. F31), some less so (HF18
= Hobie Tiger I assume by the DPN of 62.4). That file also mixes the mono hull and multihull classes all together - nothing I'm opposed to on principle, but practically speaking I think most multihull sail wave users in the US will not use the monohull ratings and vice versa.

That's why I created my file.
