About the rating :: The Mediterranean racing circuit for classic yachts is governed by the CIM regulations. Each yacht wanting to compete needs to be measured and a certificate of handicap issued. This handicap is then used to correct the real-time achieved during racing in order to compare different boats on a quasi-equivalent basis. The CIM rating is a function of a yacht’s ‘speed ‘ related to hull shape, rigging & sails arrangement, and other physical parameters as well as ‘historical’ aspects such as originality of design. From the point of view of naval architecture, there is large scope in how the CIM rating can work to the boat’s advantage.

Technical upgrades :: With objective to improve speed performance and optimise the CIM, St CHRISTOPHER  underwent a number of modifications to spars and rigging arrangement (2016-Bartel’s racing forestay, 2017- John mast) , alteration of some deck fittings and installation of a new propeller (Darglow). In 2019, aft superstructure has been rebuilt with weight-saving consideration. This year, we are installing a forestay loadcell and enhanced navigation panel.  Navalmartin will continue to undertake a range of theoretical and empirical speed performance studies related to the weight distribution and flotation waterline that will be recorded during the CIM measurements.
