Potential Class Rules are being discussed by the Hobie Class Association. Follows is a work in progress:


For some sailors, Hobie racing is about competition and the exhilaration of winning (or losing) fairly. For others, it’s the challenge, excitement, concentration and physical exertion. But for the vast majority of Ho-bie sailors, it’s about fun, camaraderie, familiar places, new places, old friends and new, and memories of fun times with people who share a love of the sport.

Like any worthwhile activity in life, there is a right way and a wrong way to participate in Hobie sailing. The Hobie Class Rules set forth in this booklet, and the ISAF Racing Rules of Sailing (RRS) as distributed by your national authority, are your guidelines to the right way to race … the Hobie way.

The rules of sailing are designed to allow all of us to compete fiercely and fairly with each other on a level sea. The rules are important for all sailors, but particularly so for one-design Hobie sailors. Each of us has a basic responsibility to be familiar with the rules. Read them, accept them and abide by them—and we’ll all have more FUN.

Be proud of your Class! Participate and become friendly with your Hobie competitors! Share your experi-ences and good times on and off the water with every new Hobie sailor you meet!

Welcome to the Hobie Way of Life! We wish you fair winds and many happy days of great sailing.

These Rules apply to all Hobie Classes

ISAF International Classes are the HOBIE Dragoon, 14,16,17,18 & Tiger

The design and development of Hobie Catama-rans and Hobie Sailing Kayaks are directed to-wards strict one-design classes where the true test is between sailors and sailing skill, and not boats. Any alterations to the hull form, construc-tion, equipment, spars, sails or running rigging, as supplied by the builder except as is specifi-cally authorized by these rules, are a breach of these rules, both in spirit and in substance, and are prohibited.

Hobie Catamarans are designed to be easy to sail with the least amount of trouble to owners. Boat and component changes, which have no direct bearing upon boat speed, are the only changes allowed. The intent and objective of the HOBIE CLASS ASSOCIATION (HCA) RULES are:

a) To keep each boat as equal, simple and cost free as possible by rigidly maintaining, without deviation, the one-design features of the Hobie Cat for class racing.

b) To increase boat speed only through the use of racing tactics and sailing skills

a) The International Hobie Class Association shall hereafter be referred to as IHCA.

b) Hobie Cat USA, Hobie Cat Europe and any of their licensees that are in good standing with their respected licensors shall hereafter be referred to as HOBIE CAT CO.

c) International Sailing Federation shall be re-ferred to as ISAF.

d) The International Sailing Federation Racing Rules of Sailing shall be referred to as the RRS.

a) The IHCA and its designated measurers are the measurement authority for the Hobie Class under the meaning of RRS 64.3.b). The IHCA has the right to declare ineligible any Hobie Cat or Hobie Sailing Kayak which does not conform to the spirit, objective and intent, as well as the letter of these rules and the official drawings and specifications held by the ISAF. In the event the drawings are not held by the ISAF they shall be held by the respective HOBIE CAT CO.

b) In the case of a dispute alleging noncompli-ance with the letter of these rules, the official drawings and specifications, the matter, to-gether with any relevant information, shall be referred to the IHCA Rules Committee who shall give a ruling under the provisions of General Class Rule 23.

c) In the case of a measurement dispute on matters not explicitly covered by these rules, the official drawings and specifications the following procedure shall be adopted:

A sample of 5 other boats shall be taken by the designated measurer and measured us-ing identical techniques. The dimensions of the disputed boat shall be equal to, or be-tween the maximum and minimum dimen-sions obtained from these 5 boats. If the boat in question is outside these dimensions the matter, together with any relevant infor-mation, shall be referred to the IHCA Chief Measurer who shall give a final ruling. If any of the dimensions of the sample are consid-ered to be unusual, all relevant information shall be referred to the IHCA Chief Measurer as well.



5.1 Boats and component parts as originally manufactured by the HOBIE CAT COMPANY are the only ones legal for class racing unless specifically permitted in these Class Rules. The manufacturing origin and trademarks of all boats shall be readily identifiable through serial num-bers, hull numbers, sails and cast parts. Copies of original invoices or warranty cards may be requested. Proof of origin shall be submitted to the IHCA or its authorized representatives for verification upon request of the jury or protest committee. Skippers or owners of boats who have had the manufacturing origin of their boat or component parts protested shall have a max-imum of two weeks to produce acceptable proof of origin.”

5.2 The ISAF plaques shall be permanently af-fixed to the transoms for all ISAF recognized classes built after January 1, 1990.

Manufacturers and distributors of non Original
Equipment Manufacturer (OEM) parts and equipment for Hobie catamarans shall obtain written approval from the IHCA prior to their parts and equipment being designated as “Hobie Class Legal.”

Nothing may be changed or removed from any
Hobie Cat that will in any way alter the structural integrity, design function, or built in safety fea-tures of the boat. All changes shall have prior written approval. Provided they do not change the basic design and configuration, approved changes are: stronger gudgeons; stronger pig-tails; larger diameter wires and running rigging; reinforced flanges not affecting water flow. Ex-cept as allowed in these rules, any changes or additions that in any way can be construed as speed devices are not class legal.


8.1 Each person on board shall carry a lifesav-ing device or Personal Flotation Device (PFD) approved by their country’s national authority or by the national authority having jurisdiction. The IHCA strongly recommends that life jackets or PFDs be worn at all times.

A paddle may be carried but shall not be used while racing other than as specified in Rule 6.7.

No minimum.

The minimum weight of a Hobie Adventure Is-land completely assembled all running gear shall be 115 lbs. (52.12 kg.) See Rule #19 of the General Rules.

The Adventure Island may be raced with or without the Mirage Drive pedaling system. The competition format shall be identified in the No-tice of Race and Sailing Instructions for the event. The competition formats are:

a) Category 1 – No Pedaling Allowed. The Mi-rage Drive may be replaced with the dag-gerboard insert or may be locked in the “fins vertical position”. A violation (pedaling) is protestable under RRS 42.1

b) Category 2 – Limited Pedaling Allowed. A limited number of pedal strokes are allowed when tacking. Once pedaling has com-menced, the tack must be completed. The number of pedal strokes allowed shall be specified in the Sailing Instructions for the event. A pedal stroke is defined as one for-ward or aft movement of one side of the Mi-rage Drive pedals. This changes RRS 42 and IHCA General Class Rule 2 b).

c) Category 3 – Unlimited Pedaling Allowed. This changes RRS 42 and IHCA General Class Rule 2 b).

d) Category 4 – Mixed Format. The race com-mittee shall display the number pennant which designates the format to be used for that race (for example, Numeral Pennant 1 – Category 1). The format may be changed at a mark rounding by the display of the appro-priate numeral pennant. The format change does not apply to a boat until they have rounded the mark at which the format change is displayed. This changes RRS 42 and IHCA General Class Rule 2 b).

It would be fun to have an modified category as well, might get some useful developments out of it? Maybe allow sail, rudder and rigging mods but the hulls and amas have to be standard. That way the boat could be setup for either without compromising the regs.

Either lead, follow, or get the hell out of the way!

How about Sprayskirts? Would they be allowed?

Sailing without them would be like, sailing naked! :)

For the past several months the Chesapeake Hobie Island Group (CHIG) has been working with Hobie to form the first official Hobie AI fleet. We received our fleet number back in June (Fleet 940, Division 11), and have been working with the fine folks at Hobie to come up with the race rules. As part of this discussion I asked the same question. The answer is that since the Turbo Fins will be standard equipment beginning with the 2010 model year, any Hobie produced fin would be considered stock and legal. With any luck, we'll soon be racing Adventure Islands in Annapolis!

In addition to Adventure Islands, we are opening things up to include the Hobie Bravo & Hobie Wave rotomolded catamarans. We already have one Bravo who comes out to play at our CHIG meetups. We'd love to see more participation from our plastic boat friends.

Happy Sailing

What does this mean?

a) Category 1 – No Pedaling Allowed. The Mi-rage Drive may be replaced with the dag-gerboard insert or may be locked in the “fins vertical position”.

I have a plastic insert that makes the bottom flush when I take out the Mirage Drive, but it has no protruding fin. The daggerboard is separate.

Now that you mention it, I think that my plastic insert does need a nice NACA foil of some kind sticking down from it. Or maybe it needs to be stronger first. Anyway, is there some accessory daggerboard plug offered by Hobie, or does that rule refer to the flush plastic plug for the MD well?

Bob, I think rule 16.4 (b) covers your spray shields
b) Storage pockets and flaps to prevent water spray may be added.

I guess it is pretty obvious that Island owners are a different crowd from sailors of other types.. we are too busy having fun to be restricted by time and course to sail! :D

The Island Club of South East Queensland has voted to commence racing. We will use the class rules as laid out and refine to suit as we go along. We have an island venue to sail from plus will manage some offshore events as well.

a) Category 1 – No Pedaling Allowed. The Mi-rage Drive may be replaced with the dag-gerboard insert or may be locked in the “fins vertical position”. A violation (pedaling) is protestable under RRS 42.1

This is the most practical way to compete with the Mirage Drive boats as counting pedal strokes is hardly practical and unlimited pedaling removes it from being a sailing race.

As some like to keep the fins in place for additional centerboard effect, Hobie has an opportunity to develop some type of simple lock to be used by those racing their Islands. A slip-over design, such as what I made and showed in one of my Youtube videos would be practical.
