Default HORBA class rules for 2011 Marathons


Class A 42 to 50 feet 3 or more engines
Class B 30 to 41 feet 2 engines
Class C 25 to 33 feet Outboards and Single Inboard
Class D 18 to 24 feet Small Boat Class
Class H Historic Open & Production class categories

Any hull design is allowed, Deep V, Cats, Trihulls etc. As long as the design is considered safe for ocean passage, it is allowed.

Boat measurement does not include any overhangs off the transoms, bustles, swim platforms etc. Measurement for length is taken from the bottom of the boat, where it joins the transom, to a line dropped from the bow.

Class C Outboards will be limited to a maximum of three motors with maximum horsepower of each outboard of 300. Outboard boats longer than 33 feet or with more than three engines of 300 HP each will move up to Class A.

Class H Historic outboards will be limited to a maximum of two modern era outboards, any horsepower, or three vintage era outboards. Vintage era outboards are 25 years old or older.

Starting time for the marathon classes:
8:00 AM Historic & Class D
8:30 AM Classes A – B - C

All classes run against the same elapsed time calculation. Historic and Class D boats will not have a 30 minute time advantage.

No turbines powered boats allowed.


We want the entrants to be as safe as possible, so we are still working with the concept of allowing canopy boats. Below are some ideas re allowing the canopy boats to compete. At this point .....they are suggestions, they are not finalized.

A.) No canopy boats unless each canopy boat provides it’s own helicopter and safety crew that will maintain it’s position over that boat for the entire length of the course. There will be no sharing of helicopters over more than a single canopy boat.

B.) Canopy boats may be altered for safety purposes by cutting the top off the canopy to allow safe exit from the boat by the crew in case of an accident. A specific sized opening will be required, as the European teams have.

We are still working with various rulebooks to come up with a complete rulebook of our own. Details will be coming in the next few weeks.

2011 Race dates

September 24, 2011 ...Don Aronow Memorial Around Long Island Marathon. Produced by National Powwerboat Association NPBA.

November 5, 2011.....Bill Wishnick Memorial Fort Lauderdale to Key West Marathon

Date TBA....Grand Haven, Mich to Chicago and back.

All classes will run the entire distance of the course for that specific marathon. Minimun marathon distance 200 miles. Fuel stops allowed if needed.

The Europeans will ship their boats over after the Cowes event in August 2011 and keep them here, for both the NY marathon and Florida marathon and then ship them back via Jacksonville.
