The Soling One Meter is a low-cost, kit-based one-design class targeted toward getting new skippers and hobbyists involved in model yachting. The Soling One Meter Class philosophy is to provide a low-cost one-design model suitable for introducing newcomers to the hobby, while offering enough performance to keep long-time model sailors interested. All aspects related to performance are intended to be restricted to what can be achieved by building the kit straight from the manufacturer's plans. Other aspects not affecting performance are not as strictly controlled. The Soling One Meter Class was introduced to the AMYA in 1993. Since that time it has become the largest class in the organization, with just over 800 boats registered in late 2006. The Soling One Meter also qualifies in the open design US One Meter Class. | |||||||||||||||
Solings must be built from a kit available from a single manufacturer, Victor Model Products of Downey, CA (http://www.victor-model.com). This manufacturer and others offer partially or fully assembled yachts. The hull and deck are vacuum formed styrene plastic, the spars are wood, sails are flat and unpaneled. Despite these limitations, the boat sails well, satisfying even veteran skippers with its balance and handling.

The Soling One Meter class is managed by the AMYA Soling One Meter Class Secretary and an appointed Class Advisory Committee. The Soling One Meter Class Rules are posted on this page.

1.0 Concept
The definitions, dimensions, limits, and restrictions listed are intended to maintain the one-design concept of this class. The concept behind the Soling One-Meter class is that a first-time skipper should be able to build and sail a model yacht that has essentially no performance differences from a boat built by an expert. All aspects related to performance are intended to be restricted to what can be achieved by building the kit straight from the manufacturer’s plans. Aspects not affecting performance are not as strictly controlled. These rules are intended to insure that all boats are as close as possible with regard to hull, deck, keel, rudder, sails, displacement and ballast. Any obvious attempt to negate or violate this concept shall require the boat be barred from competition until such time as the violation is corrected. {*Changed 2006 M1}
1.1 General
The class specification is defined by these rules, the manufacturer's plans, and any applicable rules of the AMYA, in that order. If a feature which may enhance performance is not shown on the manufacturer's plans and not specifically allowed by these rules, then it is prohibited. All dimensions shown on the manufacturer's plans are to be adhered to unless specifically overridden by these rules. {*Changed 2006 M1}
2.0 Standard
The class shall be called the "Soling One Meter". Boats conforming to these rules must be built from a kit, herein referred to as "The Kit", obtained from an approved manufacturer. The Class Secretary shall maintain a list of approved manufacturers of The Kit.
2.1 Hull and Keel
The Hull and Keel shall be as supplied in the Kit. The Keel can be removable or permanently attached to the Hull in the location shown on the control drawing.
2.2 Deck, Hatch, and Lazarette
The deck shall be that supplied in The Kit. Any method of deck attachment is permitted, provided that the deck inboard of the hull is unchanged. The deck flange, if any, may be removed. An alternate hatch cover may be fabricated, but must conform with that supplied by The Kit. One opening (hole) may be in the deck area over the rudder shaft horn assembly. This opening, to be known as the Lazarette, is optional. If it is utilized, the opening in the deck is restricted in size to a maximum of nine (9) square inches. The actual shape of the Lazarette and its covering material is uncontrolled. {*Changed 2003 M7}
2.3 Rudder
The rudder shall conform to that supplied in The Kit. The mounting location shall be as shown on the control drawing. In the event of damage to the original rudder, a replacement rudder may be fabricated as long as the replacement rudder shall be of the same size or smaller than that supplied in The Kit and conform to the original shape.
2.4 Interior Construction
The construction, layout, materials, and equipment used inside the hull is unrestricted as long as it does not conflict with any other rule.
3.0 Displacement and Ballast
The MINIMUM ready-to-sail weight of the yacht shall be 10 pounds. The ready-to-sail weight shall include the radio receiver, batteries, steering servo, sail control unit, sails and rigging.
3.1 Materials
Ballast shall consist of lead shot permanently bonded in the keel. Molded, solid lead ballast shall be prohibited.
4.0 Spars
The mast and booms shall be made of solid wood or plywood. Hollow spars are prohibited, although a slotted mast is permitted. If used, plywood must have all layers of uniform density. All replacement spars shall not exceed the dimensions of the originals contained in The Kit, except that the jib boom may be up to 15-1/2 inches long. No weight shall be added to the jib club forward of the swivel. {*Changed 2006 M1}
5.0 Rigging
The use of commercially available or home made fittings, fairleads, turnbuckles, screw eyes, eye bolts, tangs, bowsies, goosenecks, boom vangs, mast jacks, mast cranes, outhauls, etc. and woven or braided wire for shrouds, shall be permitted. Fairleads (sheet exit guides) shall not extend higher than one-half inch from the deck. Larger or through-bolted screw eyes may replace kit supplied screw eyes. {*Changed 2000 & 2006 M1}
5.1 Standing Rigging
The use of multiple diamond rigging shall be permitted. A permanent back stay is required. The ends of the spreaders shall not extend beyond the width of the hull at the mast. Spreaders shall be made of wood, aluminum or brass. Spreaders shall not be angled fore or aft of the mast. The shrouds descending from the outer ends of the spreaders shall attach either to the mast as shown in the kit plans (the diamond stays) or to the deck in the range of the General Configuration Control Drawing Note 4. If diamond stays are used and located as shown in the kit plans, a second set of stays may be attached between the spreaders and the deck in the range of the General Configuration Control Drawing Note 4. {*Changed 2001 M1 & 2006 M1 & M2}
5.2 Mast Crane - Backstay Bracket
The crane at the top of the mast may be longer than the one supplied in The Kit and/or mounted at an angle as shown on the control drawing to prevent the mainsail from interfering with the backstay. The mast crane may be constructed of wood, aluminum, or brass. The lower end of the backstay may be attached at, but not beyond the transom.
5.3 Mainsail Height
The maximum height of the mainsail from the deck shall not exceed 51-1/4 inches.
5.4 Jib Stay Attachment
The height from the deck to the jib stay attachment on the mast shall not exceed 45-3/4 inches, including the jack screw, if used.
5.5 Wind Indicators
The use of a wind indicator or vane on the top of the mast shall be permitted, and shall not be included in the restriction of 5.3.
5.6 Deck Layout
All positions of deck hardware must conform to the Soling One Meter General Configuration Control Drawing revision dated February 14, 2005. The method of attachment to the deck of any hardware is not controlled. Racks may be used on the deck in place of screw eyes. If fittings exist for alternate positions not permitted by the control drawing, the legal positions shall be clearly marked. {*Changed 2006 M1}
5.7 Mast Step
The mast must be stepped on-deck, but any mast step arrangement is permitted.
5.8 Running Rigging
Any outhauls, cunninghams and halyards shall each be attached to a single spar. The use of a separate jib halyard is permitted. Topping lifts are not permitted. {*Added 2006 M1}

Mainsail: No more than 3 battens positioned in such a way that the leach is divided into 4 equal parts. Maximum batten lengths: top 5 inches, "middle" 6 inches, bottom 4 inches.
Jib sail: No more than 2 battens positioned in such a way that the leach is divided into 3 equal parts. Maximum batten lengths: top 4 inches, bottom 2-1/2 inches.
6.3 Sail Reinforcement
The sails may be reinforced by addition of woven cloth or tape material within 3 inches of the head, tack, and clew corners, and within 1/4 inch of the leech edge.
