1) In 2010 Catalina started supplying their boats with Seldén masts and standing rigging. Current production Capri 14.2 (hulls 5449 and up) and Capri 16.5 (hulls 1050 and up) are now equipped with Seldén rigs. These boats require different mast fittings. If your boat has a Seldén rig, see "May we also suggest" below.
