You know, you should realy sign your posts with 'Frenchiely yours' :-)

As I pointed out, I am not ready to bet my life that anyone has hit >30knts on a <=20' cat. Just having fun with this :-O

From what I understand speed trials have mostly been a measure of average speed of 2 runs, one in each direction over a 500m dist (total 1km). This is not nesc an indication of top speed in any way close.
In the same respects, if a boat can travel ~695 nautical miles in 24 hours what would you say it's top speed could be.

The Course of Half a Kilometre(I know the 2 run thing isnt talked about here just something from the past)






1. General

The purpose of these rules is to enable attempts to be made on the World Sailing Speed Records in any part of the world under comparable conditions. They do not form the conditions of any prize or trophy, nor are they sailing instructions.

World Sailing Speed Records can only be established under the jurisdiction of the ISAF / WSSR Council, who shall appoint ISAF / WSSRC Commissioners to monitor all record attempts. Only Commissioners directly appointed by the Council shall have this authority. (See Rules 12 and 13.)

The official language of the ISAF / WSSR Council and its Rules is English.

The record in each class shall stand until it has been exceeded by the appropriate margin. Every request to ratify a record shall be considered in time and date order. The time used for this purpose will be Greenwich Mean Time. The time the competing craft enters the course will be considered to be the time of the run.

2. World Records

The World Sailing Speed Record will be held anywhere in the world by the skipper who establishes the fastest speed which is ratified in accordance with these Rules.

In addition, records can be established in the following sail area divisions:


10 sq. m. Class - up to and including 10 sq. m
A Class - from 10 sq. m up to and including 150 sq. ft (13.93 sq. m)
B Class - from 150 sq.ft up to and including 235 sq. ft (21.84 sq. m)
C Class - from 235 sq.ft up to and including 300 sq. ft (27.88 sq. m)
D Class - over 300 sq. ft


3. The Course

The record shall be established over a minimum of half a kilometre on water (not ice).

The course may be defined by posts and transits ashore, or by buoys afloat. Transits shall not converge.


10. Crew

At least one person shall be on board from the moment the yacht acceleerates from rest until she has finished her attempt.

All competitors shall be positively buoyant during an attempt. Weight vests and weight harnesses with a specific density greater than the water sailed on are prohibited.
