The new TEMENOS

An Open 60 foot Imoca Class boat (International Monohull Open Class Association), Temenos has make its trial sails in Pacific waters in June 2006.

the new TEMENOS

Built in New Zealand at the Southern Ocean Marine yard according to the original designs from the English firm of architects, Owen Clarke Design, the new TEMENOS will adhere to the rules imposed by the Imoca class.  Its design will benefit from its architects’ vast experience (Kingfisher, Pindar, Ecover among others) and that of its skipper (six circumnavigations, two of which were the Vendée Globe).

The skipper and architects are working on the evolution of the latest generation Open 60 footer.  Hull tank testing will validate the ideas and calculations.  The focus of the specifications will centre on weight, performance, power and reliability.  The ergonomics will be particularly sophisticated, as much on deck as in the boat’s interior.  The motivation behind this is that its skipper can be as effective as possible in organising manoeuvres when solo, both when racing and at rest.

Like all boats from the Imoca class, TEMENOS has to undergo a certain number of tests and measurements in order to obtain its measurement certificate.

TEMENOS :

• Sails aera upwind :  330m²

180°

Among these tests:

-The 180°:

Goal: Prove the quality of the monohull’s stability (a boat overturned by a wave will not remain upside down).

Procedure : The boat is turned upside down (without a mast) and the skipper, who is alone in the inside, must be able to right the boat using his own means (by canting the keel, and or filling the ballast tanks).

90°

-The 90°:

Goal: Determine the boat’s stability curve, (minimum set at 127.5° of positive stability)

Procedure: We heel the boat to 90° and the righting force at the masthead is measured.

-The 10°:

Goal: Limit the boat’s power (test without sails) and ensure that in its worst configuration case the boat shall not heel more than 10°.  The keel is canted with empty water ballast tanks until the 10° angle is achieved.  This defines the full righting moment capability relative to the 10° rule with the keel alone, though further power can be gained by adding water ballast located in such a way that it doesn’t interfere with the rule

Procedure: We cant the keel and fill the ballast tanks prior to measuring the heel angle.
