The Victoria Class is one of the largest, and most popular R/C classes.  The Appeal of the Victoria is the fact that it is a low cost boat with good performance.  While the class is officially designated as a one-design class by the AMYA, the class rules allow owners the flexibility to experiment and upgrade the rig, sails and rigging within clearly defined parameters.


1.         GENERAL

1.1        The class shall be called the "Victoria One-Design". Victoria One-Design Class Sailboats shall be built from a kit manufactured by Thunder Tiger (hereinafter “KIT”) and distributed by:

                        ACE HOBBY DISTRIBUTORS, INC.
            2055 Main Street
            Irvine, CA 92614

1.2        The class specification is defined by these AMYA class rules, the manufacturer's instruction booklet at the time the KIT was assembled, and any applicable rules of the AMYA, in that order of precedence.

1.3        The definitions, dimensions, and restrictions listed are intended to maintain the one-design concept for this class. The rules are intended to ensure that all boats are kept as close as possible with regard to hull, deck, keel, rudder, displacement, and ballast, while allowing variations in rigging and sails.

1.4        Unless a modification is specifically allowed by these class rules, it shall be prohibited.


2.         DEFINITIONS

            When a rule uses one of the following definitions, that word will be in italics.

2.1        MODIFICATION: is any alteration to a KIT-supplied component including, but not limited to, sanding, grinding, drilling, cutting, reshaping, piercing or deforming.

2.2        HULL: that portion of the hull/deck molding extending below the gunwale.

2.3        DECK: all portions of the hull/deck molding extending above and inside the gunwale including the hatch, cockpit, cockpit sidewalls, cockpit bulkhead, and transom.

2.4        KEEL: consists of the KIT-supplied plastic keel fin with attached steel shaft and KIT-supplied lead bulb.

2.5        RUDDER: consists of the KIT-supplied plastic rudder fin with attached steel shaft.



3.1        The hull, deck, keel and rudder shall be as supplied by the KIT.  No modification to shape, contour or maximum thickness shall be allowed except as expressly provided by these rules.

3.2        Hull, keel or rudder mold marks and surface imperfections may be filled or removed by sanding, polishing or painting provided the original surface contour is not altered.

3.3        The deck may not be made thinner by sanding, but may be sanded in preparation for painting and any new or existing holes or recesses in the deck may be filled with any material and faired flush with the immediately adjacent deck surface.

3.4        The trailing edge of the keel fin or rudder may be sanded to a sharp edge provided the outline shape and maximum thickness of the fin is not changed.

3.5        Keel mounting screw holes and damaged areas of the keel bulb may be filled or removed by sanding provided the original bulb profile, shape and thickness is not altered.    

3.6        Rudder profile corners shall not be rounded in excess of a 1/8 inch (3.2mm) radius.



4.1        Reinforcements for the purpose of strengthening or repairing the hull or deck may be added anywhere inside the hull.

4.2        The layout of the deck may be modified to accommodate rigging controls.

4.3        Alternate deck fittings for the jib pivot, mast step, shrouds, backstay, sheet exit guides and fairleads are permitted and their location is left to the skipper’s discretion.

4.4        New or different sheet access holes, rudder linkage holes, or holes for each of a charging jack, receiver antenna, and battery switch may be added in any location on the deck provided the hole is no larger than necessary to accommodate the fitting, but never larger than 1/2 (12.7mm) inch in diameter.

4.5        The KIT rudder linkage hole in the cockpit bulkhead, the plastic pushrod exit bushing and plastic upper rudder shaft tube bushing may be used, modified, or omitted to allow for alternate rudder control systems and any such system, including modification to the deck for such systems, is left to the skipper’s discretion.

4.6        The aft cockpit cover may be used, modified, or omitted.  A substitute material may be used to cover all or part of the cockpit.

4.7        The KIT-supplied steering columns and wheels, winches and cleats may be omitted.

4.8        A single drain hole, not exceeding 1/2 inch (12.7mm) in diameter and for the sole purpose of removing water from the hull, may be located anywhere on the deck.



5.1        Hatch cover, including the hatch slides, may be replaced with an alternate hatch cover.  Material and shape of an alternate hatch cover is left to the skipper’s discretion.

5.2        The hatch opening shape is left to the skipper’s discretion, but may not exceed 5 15/16 inches (150mm) in length and 3 9/16 inches (90mm) in width.


6.         KEEL AND BULB

6.1        KIT-supplied parts related to the keel, but not included in the definition, may be omitted or replaced.

6.2        A keel shaft tube shall be installed inside the hull and the KIT-supplied brass keel shaft tube may be replaced with any material of similar function.

6.3        The keel shaft shall not be shortened and shall be installed inside the keel shaft tube.  The top of the shaft may be re-threaded, drilled or be milled flat on any side to accommodate alternative securing methods.

6.4        The keel may be either permanently attached or removable, but must be secured in its recessed mounting slot in the hull. 

6.5        The keel depth with keel attached and secured in its recessed mounting slot in the hull, shall not exceed 7 inches (177.8mm) in depth measured, perpendicular to the waterline, from the point where the trailing edge of the keel fin intersects the hull to the bottom of keel bulb.


7.         RUDDER

7.1        A rudder shaft tube shall be installed inside the hull and the KIT-supplied brass tube may be replaced with any material of similar function.

7.2        The rudder shaft shall not be shortened.  The top of the shaft may be drilled or milled flat, on any side, to better accommodate alternate securing methods.

7.3        The number and type of connections between the rudder servo and the rudder control arm is left to the skipper’s discretion.



8.1        The minimum ready-to-sail weight shall be 4.5 pounds (2.04Kg). 

8.2        The ready-to-sail weight includes radio receiver, batteries, steering servo, sail control unit, hatch cover, the cockpit cover (if used), sails, rigging and additional ballast.
