does anybody have the portsmouth rating for a Nacra 5.5 sloop with hooter?
Thanks,
Jeff.
Hi Jeff,
They are all right here at your fingertips. Simply go back to our main welcome page and in the left hand index you will find a link to Ratings.
Good luck,

Ok, I see the ratings for a stock 5.5 sloop, but none with the expanded sail area. Does anybody know how a hooter would affect the rating of the stock boat?
Jeff- If you go to the portsmouth link on the front page and click
multihull mods
it gives a list of corrections. Your correction is coded
SP
and you multiply your standard DPN number by .972 for the shute. If it is a long distance race the correction is slighty different and listed under a different code. There are corrections for all kinds of stuff- jib/no jib, solo on a two man boat etc. The corrections are typically not as significant as one might think and probably are affected by how the course is set like the time spent reaching/running vs upwind. This stuff can get pretty controversial, but its fine for a starting point or judging relative speeds.
