Current Certificates

To view all CRF MkII certificates, visit our CRF database and search by Owner’s Name, Boat Name, Boat Class, or Record Date.

In 2019, all yachts competing in a classic regatta will need a new certificate. We also invite all owners and crew to join the Classic Yacht Owners Association (CYOA). We need your support so that CYOA can continue to support owners with rating rule administration, event management and owner advocacy. See directions below to register for a certificate.

To apply or renew is $50, you will need to login to create an account with the CRF database (which is separate from the Membership database.)

Members with multiple boats only need one account.

Step 1: Join or Renew your CYOA Membership (optional)

Membership is $100 per calendar year for an Individual Membership. Login to our portal to update your payment methods.

Members with multiple boats only need one membership.

Frequently Asked Questions:

General (11)

A. For most yachts, the data declarations for 2019 will be the same as those required in 2017 and 2018, and that data will auto-load for your 2019 application. For catboats and some additional inputs will be required.

A. Although the application is processed automatically for a rating, to ensure accuracy each certificate will be manually reviewed before it is issued. Plan on at least 5-7 business days, and if applying during July and August, it may take longer due to a larger number of certificates being issued.

A. Once processed, your will receive a link to your certificate. You may send that link to regatta organizers so they have a copy of your ratings certificate.

A. No. A boat will be allowed one configuration change only during any one season. A new CRF MkII certificate reflecting that one change must be issued at least 10 days before the next race in which the boat competes, and the boat may not revert back to her original configuration later in the same season. (This ‘one change’ limitation does not preclude correcting errors or making minor updates to declarations, which may be accepted and a new certificate issued, at the discretion of CRF administration).

A. File an inquiry and see our process here. Your request will be reviewed by CRF handicappers, and if there is an error, they will notify you, make the change in the data, and reissue your rating with the corrected measurements.

A. First, while it is possible that an input error has been made, be aware that for 2019, ratings for all yachts will be different than both their previous CRF rating and in many instances from their 2017 and 2018 CRF MkII rating.  In some instances relative to past comparable yachts, ratings may vary a great deal.   Additional variables have been used in calculating the CRF MkII, plus all subjective measurements have been eliminated so ratings may not be comparable to past years.   As for differences from the 2018 CRF MkII rating, the 2019 formulae have been adjusted to correct for observed biases in the 2018 formula.  Specifically, a more powerful Length/Beam Correction together with some minor adjustments to the Disp/Length and Sa/Disp factors, along with underbody and mast material have been made.  There is also a reduction in the rating ‘charge’ for deep draft in the Draft Correction, along with an increase in the rating credit for a shoal draft, and a deduction in the rated portion of the centerboard extension.

Of course, it is also possible that an error in data input has been made.  If you feel that this is the case, file an inquiry CRF handicappers will review if there is an error.  If so they will notify you, correct the rating, and reissue you a new certificate.

A. Certificates of all currently registered classic yachts may be viewed by going to the CERTIFICATES CRF Database.

A. The fee for a rating certificate is $50, and you must renew your certificate every year so that your rating reflects any changes to the formulae.

A. The 2019 formula has been modified to reflect biases that were identified by an objective, in-depth analysis of 2017 and 2018 race results. Specifically, yachts with a relatively narrow beam and heavy displacement (e.g. Universal and International rule racers) were observed to be advantaged, while yachts with an unusually deep draft, via either a fixed keel or centerboard, were observed to be disadvantaged. The 2019 CRF MkII ratings for nearly all yachts will change relative to their 2018 ratings, but most only slightly. Those that see a significant change will find that other yachts of the same type will have changed by a similar amount, so the competitive balance within groups should be maintained.

A. Ratings need to be renewed annually as the formula is continuously being tweaked based on new race data.

Hull and Underbody Questions (5)

A. Designers and builders typically provide displacement data referenced to the ‘design waterline’ that most often resembles a ‘light ship’ condition, with empty tanks and minimal food and gear. The weight added in equipping and provisioning for coastal cruising can increase that displacement by 10%. The boat hauling equipment in some yards can provide a boat weight, but these weights are typically not especially accurate, and should be used as a rough reality check only.

A. If you are declaring a displacement that is heavier than the designer/builder specification, it follows that your declaration for the LWL that corresponds to that heavier displacement should be longer, and that your declaration for Draft should be deeper, than the designer/builder specified values. One way to quantify the differences in LWL and Draft (DM) would be to estimate the sinkage resulting from the difference between the designer/builder spec and the declared displacement (DSPS). The ‘Pounds per Inch Immersion’ (sink) for most boats can be approximated by: Lbs/in Immer = 1.1*LWL^2. It follows that actual sinkage (in inches) = delta DSPS/Lbs per In Immer. This estimated sinkage would equal to the amount added to the designer/builder specified Draft (DM) in inches , and for most boats multiplying this sinkage by 6 approximates the amount added to the designer/builder specified LWL, also in inches.

A. Stability and wetted area are critically important performance parameters, but it is not reasonable or practical to ask owners to declare appropriate values for them. The 6 underbody types displayed on the CRF rating application work as surrogates for stability (via related keel volume, VCB and VCG), and for wetted area more directly. In addition, the various underbody type options help account for the advantages of a high aspect ratio fin with separated spade rudder over a lower aspect ratio configurations, including a full keel with an attached rudder.

A. Check the box corresponding to the underbody profile that most closely resembles the fixed portion of your keel. CRF MkII accounts for the effect of the centerboard via the declared value for ‘Draft Centerboard Down’.

A. The critical detail that would imply a ‘Type 3’ underbody would be the fact that the rudder is a free standing spade, with little or no fixed skeg area forward of the rudder.  In contrast, a ‘Type 4’ underbody features a skeg hung rudder, typically with a pintle and gudgeon type bearing near the rudder tip, and with a substantial area of fixed skeg forward of the rudder.  The presence of a shallow ventral fin (sometimes termed a ‘fence’, or  ‘bustle’, or ‘skeg’) such as those typical of IOR or International Rule yachts without a fixed skeg area over most of the depth of the rudder does not qualify for a ‘Type 4’ underbody designation.

Rig and Sail Questions (8)

A. The height of a jib headed mainsail is declared as ‘P’, which is essentially the luff length of the sail. The height of a gaff headed mainsail is declared as ‘PG’, which is the height from the mainsail tack to either the peak halyard block, or to head of a topsail (if carried), whichever is higher.

A. Under CRF MkII, gaff headed mainsails in the SOT class will be rated as ‘square headed’. Exceptions to this approach are possible in cases where the sail configuration is very intentionally designed to have an entirely traditional appearance, with the gaff length on the order of 2/3 that of the boom length. However, any such exceptions shall only be made after special consideration by, and at the discretion of, the rating authority.

A. A spinnaker is any sail set forward of the foremost mast whose width, measured between the midpoints of its luff and leech, is equal to or greater than 75% of its foot length. (See RRS 50.4)

A. This sail is by definition a headsail and not a spinnaker (See RRS 50.4), and CRF MkII will rate it as a headsail. For such a sail, ‘IG’ would be declared as the vertical distance from the sheerline to the top of the sheave supporting its halyard, and not to the upper end of the nominal foretriangle headstay. Similarly, for such a sail, ‘J’ would be declared as the horizontal distance from the forward face of the mast to the attachment point for its tack on the deck or bowsprit, and not to the nominal forestay headstay tang at the deck. And finally, the LP of this sail would be the distance from its clew to its luff, measured perpendicular to the luff, and not the LP of a smaller sail set in the nominal foretriangle. Note that CRF MkII will rate the speed potential of the boat with this sail in its best condition, and that the rating with such a sail will be ‘faster’ than it would be with a smaller headsail set in the nominal foretriangle, even when only that smaller sail is flown. Note further that some race organizers will require that such a headsail must have its luff attached to a stay, and that it cannot be set free flying.

A. ‘TPS’ is the distance from the forward face of the mast to the attachment point for an a-sail tack to the deck, to an anchor roller, to a bowsprit, or to a similar fixture. If an a-sail is tacked to the stem near the headstay tang, ‘TPS’ is nearly equal to ‘J’, the length of the foretriangle base. If an a-sail is tacked further forward to the end of an overhanging stem or to a bowsprit, ‘TPS’ will be significantly larger than ‘J’, the rated area of that a-sail will be bigger, and the rating will be faster. Under CRF MkII the change in rating for increasing ‘TPS’ is generally in line with that of other handicapping systems.

A. Any pole used in trimming a spinnaker is a spinnaker pole, and it is rated as such with its overall length declared as ‘SPL’. A whisker pole is a pole used to wing out headsails only, and its length is limited to not more than 1.1*’J’. A spinnaker pole with a declared length not longer than 1.1*’J’ can be used as a whisker pole to trim headsails. A boat can use a spinnaker pole with either symmetrical or asymmetrical spinnakers, but if a spinnaker pole is declared, the boat will be rated for an s-sail spinnaker area, whether or not she actually carries any s-sails.

A. Yes, as long as you declare a spinnaker pole length ‘SPL’. If you declare both a pole length ‘SPL’ and a spinnaker tack point ‘TPS’, CRF MkII will calculate a spinnaker area for both an s-sail via SPL, and an a-sail via TPS, and it will calculate rating on whichever area is larger.

A. Yes, as long as you declare a spinnaker pole length ‘SPL’. Note that a whisker pole can only be used to wing out a headsail, and not to trim a spinnaker. Also, be aware that if you do declare an ‘SPL’, your calculated spinnaker area will be larger, and your rating will be faster, than it would be if you declare just a centerline a-sail tack point ‘TPS’ with a length equal to that ‘SPL’. This higher rating is due to the fact that being able to square back a spinnaker pole increases projected spinnaker area and in some conditions it allows a boat to sail at deeper true wind angles off the wind, resulting in potentially higher downwind VMG.
