(a) The Stewart 34 was designed to be a fast racing/cruising yacht to fulfil the recreational needs of a sailing family for weekend and holiday cruising and harbour and gulf racing. These class rules have been designed to preserve the following characteristics in every possible way.

      1. Comfortable family cruising
      2. Low cost ownership
      3. Tight one-design racing

When racing as one design the intent is that all yachts will be basically equal and that racing will be a test of sailing ability. Any attempt to alter a yacht, its sails or its rigging except as is authorised by these rules, will be considered a breach of these rules, both in
spirit and substance.

(b) These class rules however cannot anticipate every possible situation which may arise.
Economical improvements which assist the class to continue to progress and to be competitive are encouraged but members should discuss such improvements with the Committee if in any doubt about the legality of such improvements under these rules.
In making alteration to the rules the Association will follow the Stewart 34 basic philosophy, viz. a one-design class which prohibits innovations which would give a speed advantage to any one yacht.

In the event of any owner introducing any alternative or new idea to his yacht, sails or rig, other than minor, that a majority of the Committee or a majority of the owners present at an official Owners’ Meeting, considers an innovation, such alteration or new idea shall be an innovation. The owner then has the responsibility of endeavouring to alter the rules to include such innovations in accordance with Rule 14 of the Constitution.

(c) It is the sole responsibility of the owner to check and see that the yacht, its spars, sails and equipment, comply with the current class rules. (Statements written or verbal from individuals and companies other than the Class Measurers or Committee Members should
be ignored).

(d) On receipt of a complaint from a member of the Association the Committee reserves the right to ask the Measurer or those also appointed as measurers to check any yacht on any rules at any time. Should discrepancies occur the Committee has the right to

(1) Debar such yacht from competing in further Stewart 34 races
until the discrepancies have been made good, and

(2) to allow the Chairman, Secretary and one other Committee
Member, without calling a full Committee meeting, to
instruct the Secretary to enter a protest against such a yacht
if the time limit for such a protest has not expired.

(3) The owner of the boat will be responsible for all reasonable costs

(e) Should the alleged discrepancies in Rule 1 (d) not be proven to the Measurers satisfaction the costs incurred shall be borne by the members who asked for the measurement to be made.


All future yachts must be built to the plans and these class rules, with no tolerance in excess of those the Measurer considers acceptable. New owners are urged to contact the Committee
before commencing construction.

(a) The notes on the plans are to be carefully observed, viz. that no intentional deviations from the plans are permitted.

(b) The silhouette for yachts be preserved as drawn on the plan by Bob Stewart for a wooden boat or, if of fibreglass construction, on the plan for the G.R.P. mould.

(c) The minimum motor weight to be 275 lbs (124.74 kilos) including batteries and compressor if any, and if lighter motors are used, weights equivalent to the difference must be carried in the motor position. Batteries may be permanently placed in any part of
the boat except where they are used to bring the motor up to weight, when they shall be placed in the motor position, but in any event the batteries may not weigh more than 110 lbs (49.90 kilos).

(d) The most forward part of the motor must not be placed more than 11’6” (3.51 metres) from the tuck on all future boats. In the event of any existing boat replacing a motor the new motor shall be no more than 11’6” (3.51 metres) from the tuck and not further
forward than the original position whichever is the greater distance.

(e) A fold-down or open transom exit from the cockpit in accordance with the drawing attached to the official plans will be approved provided that such a transom exit be securely closed at all times whilst racing.

(f) Sail drive auxiliary motors are permitted provided no part of the motor or sail drive unit is further forward than 11’6” (3.51 metres) from the tuck.
