The K1 single-handed performance keelboat heralds a new era of single-handed sailing; combining speed, style and ease of sailing. This unique mini yacht has a lifting keel with bulb weighing 62 kg yet its all-up weight is little more than a conventional single-handed dinghy. The hull is constructed using the latest resin infusion techniques to minimise weight. The carbon spars are ultra-light and responsive.

The slender hull has little resistance when heeled so is quick and tacks through a very narrow-angle. The self-tacking jib is set on a pole for maximum ease of control. The cockpit is deep and comfortable when sitting on the deck edge. The result is a boat that is an absolute joy to sail and guaranteed to provide effortless, fast sailing and close tactical racing.

From 2020 the K1 is being built by Ovington. Details and pictures of any changes will be published as soon as we get sight of one.

Although the details can tell you all about the boat they cannot convey the fun that you get sailing the boat. It is a very responsive boat that forgives so many errors on the helm’s part. When you get the feel of the boat it responds so quickly to any small adjustments that it ends up “fitting like a glove”.

It is a joy that really does get better as the wind builds and the helm has the confidence that the boat will in, nearly all, circumstances just roll back up with you onboard and ready to sail away.

It has proven itself to be a fine sea boat as well as finding good homes in lakes and rivers of all sizes.

In more detail…

The K1 was designed by Reigate-based Paul Handley, who’s previous portfolio includes the RS Feva, Tera, Q’BA and K6 as well as (in the dark distant past) the Mustang 30.

Changes to the hull

The K1 is a single-handed one-design performance keelboat. It has been designed according to the principle that the racing results should depend solely on the attributes and skills of the crew. The fundamental objective of these class rules is to ensure that this concept is maintained.


As such it is the intention to avoid alterations to the Class as far as is practicable. Therefore, even though the builder changed from Synthesize (for the first 72 boats) to Rondar (until number 151) and now to Ovington, t was important to ensure that all hulls were all the same shape (from the same mould). Therefore no matter what age boat you purchase, then hull shape will be the same. This is despite minor changes to rigging and sail supplier.

Changes to the rigging

The carbon fibre masts and boom specification has remained the same from the beginning. The only variations on rigging have been choice of centre sheeting for the jib vs side sheeting (used originally) and the option of a dangly pole for the jib setting.

Owners can, and do, experiment with different controls and fittings such as refreshed kicker arrangement or cunningham controls.. This is allowed as long as no holes are drilled into the boats. It is very important to read the Class Rules before undertaking such modifications.

Changes to the Sails

The sails changed from Hyde to North at the request of the class association. The North sails have a squarer head and softer mylar cloth. Hyde and now North are the only class legal sails except for reduced size sails as specified in the class rules.
