Bylaws/Rules for Waves:

February 18, 2001,

2001 International Wave Class Rules -Final Draft

The Wave will be sailed stock, as designed and as sold by the factory, per the following explanations and exceptions

1. One-Design Class Racing
The design and development of the Hobie Wave is directed toward a strict one-design class where the true test is between sailors and sailing skill, and not boats. Any alterations to the hull form, construction, equipment, spars, sails or running rigging as supplied by the builder except as is specifically authorized by these rules, are a breach of these rules, both in spirit and in substance, and are prohibited.

2. Intent and Objective
The Hobie Wave is designed to be easy to sail with the least amount of trouble to owners. Only changes which have no direct bearing upon boat speed are allowed. The intents and objective of the Hobie Wave Class Association are:
2.1 To keep each boat as equal, simple and cost free as possible by rigidly maintaining, without deviation, the one-design features of the Hobie Wave for class racing.
2.2 To encourage the use of racing tactics and sailing skills only to increase boat speed.
2.3 To have the boat appeal to as many people as possible.

3. Definitions
3.1 The International Wave Class Association shall hereafter be referred to as IWCA.
3.2 Hobie Cat USA, Hobie Cat Europe and any of their licensees that are in good standing with respected licensors shall hereafter be referred to as Hobie Cat Co.
3.3 International Sailing Federation shall be referred to as the ISAF.
3.4 The International Sailing Federation Racing Rules shall be referred to as the RRS.

4. Eligibility
The IWCA has the right to declare ineligible any Hobie Wave which does not conform to the spirit, objective and intent, as well as the letter of these rules and official drawing and specifications held by the IWCA. In the event the drawings are not held by the IWCA, they shall be held by the respective Hobie Cat Co.

5. Loopholes
If you think you have found a loophole, read the preceding statements again. These are the basis of the rules and cover all areas not covered in the rules. Generally, if you cannot find it listed in the Rules, it is not class legal. If you are in doubt, check with the IWCA first. Approval must be in writing by the Rules Chairman or his designee.

6. Design Features and Changes
Only Waves manufactured by the Hobie Cat Co. are legal for class racing. Nothing may be changed or removed from any Hobie Wave that will in any way alter the structural integrity, design function, or built-in safety features of the boat. Changes that fall under the category of safety and strength shall have prior written approval. Approved changes are as follows: Stronger gudgeons, larger diameter wires , slight shimming of crossbars, and reinforced flanges not affecting water flow. Except as allowed in these rules, any changes or additions that in any way can be construed as speed devices are not class legal.

7. Safety Equipment
7.1 Each person on board shall carry a lifesaving device or PFD (Personal Flotation Device) approved by the recognized authority having jurisdiction. IWCA recommends that life jackets or PFDs be worn at all times.
7.2 A minimum 5/16" diameter righting line or webbing consisting of at least one 13 foot length of line or webbing, or two 7 foot lengths of line or webbing shall be securely attached to the boat and readily available on either side of the boat.
(Righting water bags, shroud lengthening devices, righting- pole type devices, and righting systems other than the minimum system specified may be carried and shall be used for righting purposes only)
