Notice of Race / Sailing Instructions – One Star Challenge 2021

rev. 2021-05-10

Information regarding Coronavirus

Due to the Corona virus the social activities will be limited like it was at last year’s race. We will make the race as Corona-safe as possible. This means following the guidelines and rules dictated by the Danish government at any time. Information regarding this will be updated regularly on the event-website.

One Star Challenge 2021 is open to foreign sailors. However – if covid-19 travel restrictions prevent foreigners from participating in a legal manor, the signup will be annulled and the signup fee refunded.

A skippers briefing might not be held. All information will be sent by mail and published on the event-website.


The idea behind One Star Challenge is to host a straightforward friendly race for Singlehanded sailors in the most beautiful waters of Denmark. We try to keep the number of rules to a minimum, but we still need a common set of ground rules. Our primary focus for these rules is to increase safety.

The race is carried out under flag and governed by the International Seaway Regulations (COLREGS) with the special regulations for navigation in certain Danish waters.

A race license is not required, and no corrected results are calculated based on ratings. This also means that we do not require sails to be measured, and you can bring as many as you like.

Participating boats are divided into races based on size (LOA, 1 foot = 0.3048m) and type:

  • Small, 18-26 feet
  • Medium, 26.01-32 feet
  • Large, 32.01 feet and up
  • Multihull
  • BIG boat, all boats sailing the Bigboat-route

The first boat for each race to cross the finish line is the winner.
The winner of each race will receive the race trophy from last year’s winner.
(The winner from last year is obligated to bring the trophy to Køge Sejlklub before the race starts – even if you are not racing this year.)

Race office

On arrival to the marina the participants must check-in and receive a t-shirt, boat number, last minutes information’s and maybe some other things.

Safety equipment

We do not compromise on safety. But it is the participants own responsibility to accommodate the safety recommendations.

All participating boats must be in seaworthy condition and we reserve the right to reject boats/participants which we do not consider fit to participate in the race.

We also require all participants to bring/use the following safety equipment:

Navigation lights

All participants will experience sailing in the dark. Therefore, all boats must carry lanterns/navigation lights as described in the maritime regulations. Participating boats under 7 meters must comply with the rules for boats over 7 meters.

The use of engine

It is allowed to use the engine during the race for charging batteries without driving the propeller. It is also allowed to use the engine in the event of an emergency, to avoid collision or running aground, and to assist another vessel in distress.

Furthermore, the engine may be used while entering an emergency port from within a radius of 200 m from the port entrance.

Any use of engine for propulsion should be noted and reported to the race office immediately after finishing the race.

Start numbers, race markings and advertising

All participating boats are obliged to mount start numbers and any advertising for the race sponsors, which is supplied at registration.


All participants must have a shorecrew of one or more persons, which can contribute to the contact between the race committee and the participant. The shorecrew should also assist the participant by supplying weather reports, moral support, and guidance along the way. It is recommended that the shorecrew is knowledgeable about sailing and knows the participant well.

Contact information

When checking in at the Race Office the participants must state the following:

  • Own mobile number
  • Name(s) and phone number for shorecrew

The race committee may at any time choose to postpone or cancel the race, if for example weather conditions are considered to be a risk to the participants. If the race is canceled the participants are not entitled to a refund.
