it depends!
Scott:The only way to find out your actual PHRF rating is to apply to your region for a PHRF certificate for your specific boat. Your precise rating will depend on the configuration of your boat, sails, keel, etc. The New England PHRF lists one Beneteau 311 at 183 this rating does not delineate if any credits were given for such things as fixed or folding props, roller furling, head sail size, etc. That same PHRF list includes a Beneteau 331 at 171. This is the same rating (171) I received for my Beneteau 331 "PATRIOT" under Chesapeake Bay PHRF rating. I have seen west coast ratings for the Beneteau 331 as low as 144. My base PHRF here on the Chesapeake Bay is 156 plus credits, in my case for fixed three blade prop and above deck roller furling headsail. Hope this helps.regards,Dave HumphreysBeneteau 331 "PATRIOT"Annapolis
