General Description:

Length Overall (LOA): any

Displacement:  Minimum: any

Mast Height: not to exceed 73feet above the deck.

1.0 CONCEPT

The definitions, dimensions, and restrictions listed are intended to maintain the all-design concept for this class. The rules are intended to make it clear that anything goes with regard to hull, deck, keel, rudder, displacement, rig, sails and ballast. In these rules the word "shall" means mandatory while the word "may" is permissive. The objective is that an “Out of the Box” Sailboat won't have a chance without the need to replace major components . However minor low cost improvements within the spirit of the rules may be necessary to make the production boat at least semi competitiive. Costly modifications to enhance performance are right in line with the spirit of these rules. It is hoped that the Sailboats will provide very close racing no matter what the cost.

1.1 General

The class specification is defined by these KMYC class rules, the manufacturer's kit at the time the kit was assembled, and any applicable rules that we come up with at the pond, in that order of precedence.

2.0 STANDARDS

The class shall be called "As long as it Sails". Boats conforming to these rules must be assembled from a kit, herein referred to as "the Kit". "The Kit" is anything you can come up with to make a sailboat.

2.1 Hull and Keel

The hull and keel shall be as supplied by the Kit but may be reinforced internally or externally for collision protection and may be modified in any other way..

2.2 Deck and Hatch

The deck shall remain as supplied by the kit, but new or different sheet access holes may be added. The Hatch cover shall be that as supplied in "The Kit" and referred to as "the cabin" in the manufacturers assembly guide book.

2.3 Rudder

The rudder shall be as supplied by the Kit. If damaged or broken a new one may be obtained from the manufacturer or rebuilt by the skipper so that it is of any size and shape.

3.0 DISPLACEMENT AND BALLAST

There is no minimum ready-to-race weight.. The ready-to-race weight includes radio receiver, batteries, steering servo, sail control unit, sails and rigging.

3.1 Materials

Ballast shall consist of lead added to the keel as included in the kit. Additional ballast of lead may be added to the interior of the hull to attain the minimum weight.

4.0 SPARS

The mast and booms may be made of aluminium or anything else you like. Hollow spars are allowed.

Fittings attached to spars are not considered part of spars.

5.0 RIGGING

Running and standing rigging may use commercially available or home built fittings, fairleads, turnbuckles, screw eyes, bowsies, goosenecks, spreaders, etc. The type of line or wire used for sheets or shrouds, etc. is not controlled. Reinforcements may be added under the deck at the chainplates, backstay attachment points, sheet exit guides, and jibstay attachment point.

The original standing rigging layout shall be retained, comprising of an adjustable, permanent backstay, upper and lower side shrouds and a jibstay, to which a jib boom topping lift may be added. The use of separate halyard control lines for the jib and main is permissible.

Boom vang is free of any restrictions and may be of any material.

5.2 Mast Crane and Backstay Bracket

Go for it

5.2.1 Mast Fittings

The use of different or replacement mast fittings is not controlled and spreaders are free.

5.3 Wind Indicators

The use of a wind indicator or vane on the top of the mast is allowed, and shall not be included in the restriction on mast height (see 4.0).

5.4 Deck Layout: The layout (not dimensions) of the deck may be modified as needed to accommodate alternate control systems (see 5.5). The steering column and wheels, deck railings, winches and cleats need not be attached and the cabin area may be sealed. Alternate deck fittings may be used.

5.5 Alternate Sail Controls

The manner in which the main and jib sheets are rigged and controlled is left to the skipper's discretion.

6.0 SAILS (See Also APPENDIX #1 Sail Diagram and Measurements)

6.1 Sail material shall be spinnaker cloth, e.g ripstop nylon such as that as supplied in the kit, as available at commercial sail makers with the weight and colour of cloth left to the skipper’s discretion. Moulded sails are specifically allowed . Mylar and Kevlar sail materials are specifically included. The use of stickyback for reinforcement is permitted.

6.2 Corner reinforcements, batten pockets and battens are unrestricted as to material.

6.3 Corner reinforcements may extend as you see fit

6.4 Halyard, downhaul, and clew outhaul attachment points shall be placed wherever.

6.41 A cunningham eye is allowed on either sail.

6.5 Battens may be fitted to the mainsail and jib. They shall be placed so as to divide the leach into approximately equal segments. Their maximum length shall be as per the original sail battens supplied with "The Kit".i.e. a maximum of 95mm for the main and 65mm for the jib but may at the skippers discretion be shorter or longer or removed.

6.6 Sails, when measured, shall be measured OFF the spar. See also Appendix 1 which relates to maximum dimensions.

6.7 Foot and leach curves shall be defined by the measurement points and faired with a constant section batten connecting corners of the sail through the intervening measurement points, with no bending in the batten induced beyond the corners of the sail.

6.8 Sail Numbers and Class Logo

The Sail number (when assigned by The Registrar) must be displayed on all sails (the use of the class logo is optional an shall be displayed only on mainsails when used). Sail Numbers are assigned by The Registrar. The class logo is a stylized "A" as detailed in Appendix #2. Sail numbers are to be no less than 60mm tall, and are not restricted in terms of colour. If desired owners may display their assigned sail number on the hull or deck of their boat. These numbers shall be no more than 20mm high.

6.8.1 National Identifier

If desired, a three letter national identifier may be precede sail number. For Alaska this is AK. This shall be displayed in the lower 1/3 of the mainsail only.

6.8.2 Placement

Sail numbers shall be placed on the main sail, in the upper half of the sail. They are to be placed on the jib in the lower half of the sail. The starboard side sail numbers shall be placed higher than the port side sail numbers.
