1. All boats seeking recognition as a Catalina 250 Class Racing Sloop must be made from molds approved by the Catalina 25/250 National Association, herein to be known as the Association.

2. Any modification to the hull and/or deck of the Catalina 250 must be approved in writing by the Rules Committee of the Association unless specifically permitted herein.

3. Modifications to the interior of the boat may not decrease the structural integrity of the boat. Specifically, changes made for the purpose of weight distribution will not be allowed.

4. Due to design differences and production options, all C250 boats will race with handicap ratings according to Section F. Ratings.


1. Rudders shall be made from a mold commercially available to all competitors. (Rudders manufactured for C-250s by Catalina Yachts or elsewhere prior to the publication and association approval of these rules are considered to be approved. In the case where the rudders are obviously different from those now being manufactured, proof of origin may be required.)

2. Changes to the rudder to affect weight distribution will not be allowed.

3. Beaching rudders will be allowed provided they comply with B-1.

4. Modification to gudgeons will be allowed for the purposes of balancing pressure on the helm.

5.  For the period beginning October 1, 2005 through October 1, 2008 when racing in a race governed by these class rules (as indicated in the Sailing Instructions or Notice of Race) all rudders that are not original equipment must be declared on the racing application. 



1. Keels may be either retractable (centerboard) or fixed. In either case, they shall be as supplied by the manufacturer. They shall remain unmodified in composition, size, and shape. Refinishing the surface of the keel shall not be considered a modification.

Non-Spinnaker (JAM) boats: (4 sail limit)
1 Mainsail
3 Headsails *

* Boats that were originally built and supplied with jib sails larger than 110% will be allowed with appropriate handicap ratings. In any one regatta the same sails must be used to fill the requirements of this section, unless there are extenuating circumstances, in which case the measuring official may waive this requirement.

In any one regatta the same sails must be used to fill the requirements of this section, unless there are extenuating circumstances, in which case the measuring official may waive this requirement.

a. Spinnaker sails are authorized and may be used in the National Championship Regatta and all sanctioned Regattas as a separate or combined spinnaker class with appropriate handicap. Only two measured spinnakers may be used in the same regatta.

b.  Change to Asymmetrical spinnakers are allowed but must not have a sail area greater than an allowed  symmetrical spinnaker.


2. Measurement of sails

a. General

(1) Sails shall be measured in a dry state laid on a flat surface with just enough tension to remove wrinkles across the line of measurement being taken.

(2) The term "sail" shall be taken to include the headboard, tabling, bolt and foot ropes (or tapes). It shall not include cringles which are totally outside of the sail.

(3) Windows may not have an area greater than 3 square feet (including telltale windows), in any one sail, nor may be closer than 6 inches to any edge.

(4) For the National Championship Regatta, that suit of sails which a competitor intends to use shall be submitted upon request prior to the start of the first official race, and marked by the Chief Measurer or his designated representative. The mark shall not exceed 6 inch tall and 2 inches wide and should keep with the latest sail-makers and measurers mark standard whenever possible.

5a. It is at the discretion of the Chief Measurer or his designate which sails from any vessels suit of sails shall be measured, if any.  The absence of an official measuring at or prior to any regatta does not indicate approval of sails not meeting the guidelines set forth herein.


b. Definitions

(1) Head - The head shall be taken as the highest point of the sail projected perpendicular to the luff or its extension.

(2) Clew - The clew shall be taken as the aftermost point of the sail projected to the foot or its extension.

c. Mainsails

(1) Luff - The length of the luff shall be taken as the distance between the uppermost point and the lowermost point of the leading edge of the sail. The dimension shall not exceed:
Tall Rig - 27.5'; Standard Rig - 24.5.

(2) Foot - The length of the foot shall be taken as the distance between the forwardmost and aftermost points of the lower edge of the sail. The dimension shall not exceed 11'.

(3) Battens - The mainsail shall have four battens with no maximum length restriction.

d. Headsails

(1) Luff - The luff shall normally be the distance between the lowest part of the sail on the luff rope or wire and the head. At the discretion of the measurer, if it appears that there has been liberty taken so as to take advantage of this rule in order to build a sail longer than would ordinarily be permitted under this rule, the point of measurement at the tack shall be taken as the point of intersection of the luff of the sail or the luff extended, and the foot of the sail or the foot extended, ignoring any round or hollow of the foot. Likewise the point of measurement of the head of the sail shall be taken as the point of intersection of the luff of the sail, or luff extended, and the leech of the sail extended ignoring any round or hollow of the leech. The dimension shall not exceed: Tall Rig - 32.5'; Standard Rig - 29.5'. The luff shall be attached to the forestay by either a head foil OR a minimum of four (4) hanks (or similar mechanisms) equally spaced along the luff between the tack and the head of the sail.

(2) Longest Perpendicular - The "LP" shall be measured on the perpendicular from the luff (outside edge) to the clew. The dimension shall not exceed 12.15'.

e. Spinnakers

(1) Luff - The length of the luffs shall be taken as the distance between the highest point of the sail and the foot measured around the edge of the luff. The dimension shall not exceed: Tall Rig - 32.025'; Standard Rig - 29.286'.

(2) Girth - The maximum shall be measured across the widest point of the sail between points equidistant from the head. The dimension shall not exceed 16.2'.

3. Fleet Measurer

Each fleet will, through normal procedures as set forth in fleet by-laws, select a fleet measurer. The name of the measurer will be sent to the Association. Upon measuring a set of sails and finding that they comply with rules set forth herein, the measurer will affix to the area near the tack of each sail measured: C-250, his initials, and three numbers indicating the month measured and the last two digits of the year measured. For example the numbers"4 - 00" indicate that the sails were measured in April of 2000.


1. All boats shall be rated according to the current area PHRF rating of the host fleet as available to them. Fixed keel and centerboard boats with tall and standard rigs will be rated accordingly.

2. Rating adjustments will be allowed as follows: Inboard engines, fixed prop +.1; and inboard engines, folding prop +.05. Adjustments for appropriate headsail size will be made.

3.   Any Overall competition between C25/C250 or Capri 25 sail boats, is not discouraged and shall be rated between the three boat types, at the discretion of the Host Club and their local PHRF Organization these rating shall be posted in the notice of race.
