Proposed Rule Change for the Ensign Class Association
Roller Furling: Part II, 9 L
Name of Proposer: ECA Governing Board
Proposal Date: January 2019
Discussion Cut Off Date: June 1, 2019
Anticipated Membership Vote: June 2019
Rationale:
Regarding Roller Furling Systems and Headsails…
Proposed changes seek to address the following:
- Current rules were unintentionally written in such a way as to mandate that head foils and luff tapes MUST be used on all installed roller furling systems. At the time of the rules’ writing, no commercially available roller furling systems came WITHOUT a head foil, which is a situation that has changed. The rule has been re-written to also include boats with roller furling systems that do NOT incorporate a head foil, whose headsails are NOT fitted with luff tape, but instead are attached to the forestay using hanks made of metal and/or plastic (just like the headsails on boats lacking roller furling).
- The current rules fail to specify materials and weights for roller furling headsails other than the No. 1 genoa. Materials and weights for the No. 2, Working Jib and Blade should also be specified.
- The current rules unnecessarily reiterated specifications on maximum size, and inappropriately removed “minus tolerances” for roller furler headsails. Not having a minus tolerance makes it possible to build roller furling headsails of any LP, and therefore a minus tolerance should be specified.

CURRENT RULE: (Too much change to indicate change areas. The rule has been re-written.)
Part II, 9 L. ROLLER-FURLED HEADSAIL: An optional roller-furled headsail may be fitted instead of the headsails with metal and/or plastic hanks described in sections H., I., J., K. of this rule. A roller-furled headsail, if fitted, will conform to the following rules.
1. A roller-furled headsail shall be fitted with a luff tape and will be attached to the forestay by a operational head foil and roller-furling hardware. The design of the head foil and roller-furling hardware shall be optional.
2. Except for the UV protecting fabric at the leech, all roller-furled headsails shall be made of Dacron, 4.5 ounces per running yard, 28 ½” wide. (Width for weight specifiation only). An exception is provided for the UV protecting fabric at the leech. The selection of UV protecting fabric is optional.
3. The maximum size of each roller-furled headsail shall be governed by the maximum measurements provided in Rule 9. I of this part.
4. The minus tolerance on all dimensions is unspecified. Luff, Foot, Leech and head to mid-foot dimensions are as necessary such that the sail will properly furl but in no case will any maximum dimensions provided in Rule 9. I be exceeded.
5. No additional halyards may be fitted. The jib halyard and its fittings must conform to the specifications found in Rule 7 of this part. The attachment point of the jib halyard tang shall not be altered.
6. The length of the forestay is as specified in Rule 6 of this part and includes all roller-furling hardware.

PROPOSED RULE CHANGE: (Too much change to indicate change areas. The rule has been re-written.)
Part II, 9 L. ROLLER-FURLERS AND HEADSAILS: A roller-furler of optional, above-deck design may be fitted to the forestay. The use of a roller-furler system, if fitted, shall conform to the following rules:
1. Headsails for roller-furler systems that incorporate an operational head foil shall be fitted with the appropriate luff tape, and set through use of the head foil.
2. Material, weight and size specifications for roller-furled headsails are defined by Part II Rule 9 H., I., J., and K. An exception is provided for any UV protection fabric applied to the leech. The selection of UV protection fabric is optional.
3. No additional halyards may be fitted. The jib halyard, its attachment point, hardware and fittings must conform to the specifications in Part II Rule 7.
4. The length of the forestay is as specified in Part II Rule 6 and shall include all roller-furling hardware.
