when does CSF make a difference?
There really are no easy sources. PHRF of Long Island Sound has a lot of information on their ratings page but you still have to go to Carl''s Calculator to get the numbers crunched. The IMS has a very detailed source of information about boats measured for the IMS but it is not all that easy to get that data. I understand that the CE has a summary of information on boats certified under the Small Craft Directive but I have not found a source of that summary either.
