They had lack of knowledge, skills, PFDs, harnesses, etc. Also lack of simple sealing the mast so it won't leak and therefore turtle. This is why we use to have Hobie Fleet Sailing clubs, to share good times, information, teach sailing skills, and to safety check each other's boats. Its too damn bad the Hobie and Prindle fleets have mostly gone away. BUT--- NO PROBLEM---- MODERN PEOPLE GET IT ALL FROM THE INTERNET! HAhahahaahaha!
