Six Metre Yachts Classic Rules

So that the widest possible number of Classic owners can consider them and give their views, here is the first draft of the Classic Rules for review.

  1. A Classic Six-Metre is a boat designed and built prior to 31st December 1965.
  2. All boats must conform to current International Six-Metre Class Rules, including deck equipment, mast and rigging.
  3. The hull shape shall be consistent with the original design intent. Classic boats are permitted only one moving underwater appendage, which shall be a rudder mounted on the aft end of the keel, unless otherwise designed originally. Boats built to Rule 1 and Rule 2 may be updated to a configuration consistent with a pre-1965 interpretation of Rule 3 but, unless incorporated in the original design, are not permitted a bustle, a spade rudder or a separate skeg and rudder configuration. (see Note 1 below).
  4. A boat whose underwater shape has been modified to a post-1965 design, may regain its’ classic status, if the boat is returned to its’ pre-1965 underwater configuration and re-measured.
  5. Laminated frames using modern glues are permitted to replace broken or decayed frames. Reinforcement of the hull by the addition of a maximum of four laminated or plywood ring frames, using modern glues, is permitted: two in way of the mast partners and two in way of the running backstay turning blocks or attachments only.
  6. With the exception of decking, ring frames, splash boards and minor outfitting items of a non-structural nature such as storage lockers and floorboards, the use of plywood is not permitted in restoration. However, this rule shall not invalidate the use of plywood to effect short-term temporary repairs.
  7. Replacement planking shall conform to the original construction method and scantlings. An additional single external wooden veneer skin is permitted, provided any such addition is still permitted within the current International Six-Metre Class Rules. (see Note 2).
  8. All Classic Six-Metres shall hold a valid measurement certificate.

Note 1. A number of boats built pre-1940, actually include bustles, spade rudders and/or a separate skeg and rudder. The ones that I know of are, or were, Josephine, Eyra, Maida II and Noroda, all British. However these have all been destroyed, but there may be others, which will have to be dealt with individually.

Note 2. Since these Rules were drafted, it has come to my notice that at least one boat has had her double skin construction removed and replaced with normal, old-fashioned, mahogany planking. As this was done, it is believed, prior to 1965, it is considered that she, and any others which may have been dealt with similarly, should be accepted as “Classics” and thus “grandfathered”.

Note 3. There are a number of wooden boats, mostly designed by Willi Lehmann and built in East Germany between 1965 and 1971 which, although they are post 1965 should, more correctly, be designated as classics as, in some cases, they were actually designed pre-1965. Both by their design and their build, they really fit into the “classic” ethos and, especially in their speed, would appear to more resemble the classics. Local rules may have to be adjusted to take account of them. Perhaps, if anyone has views or comments, they might let Leif Bockelman, Chairman of the ISMA Classics Committee, Hans Oen or myself, know their views. During the year Matt Cockburn of Seattle produced the First Draft of the Classic Rules. These were augmented by Tim Street and Tim Russell of England and then refined by Hans Oen, who, after a fairly wide circulation, submitted them for ratification, to the AGM at St. Tropez. However, as it was thought that there had not been enough consultation, they were referred back to the Classics Committee. So that the widest possible number of Classic owners can consider them and give their views, here they are.
