Hurricane 5.9 designed and built by Req White in Uk is remarkably similar to the Miracle 20 ,theres a story behind it too , but apparently thats a secret !, anyway point being as the miracle 20 is virtually the US version of the Hurriucane 5.9 you should find that that it too should be able to carry a spinnaker with no trouble , most of the UK fleet have updated and converted to the SX version with integral chute etc and has been officially adopted by the class , with the Dollar giving the UK pound a kicking at the moment might even be worth getting the whole kit sent over .Andy Webbs your man .



Check out http://www.hurricane59.com/,for further info , they have also developed a new square top main .

sounds like good ole reg white did a better job of building the 5.9 too , with old boats updated still being competitive and no horror stories of breakages like the M20
