I was doing some web sailing on this cold January day (about 8 degrees here) and read the write up in the sailing hall of fame for the daysailer, which was inducted in 2003. The article showed the DS first released in 1958 meaning our DS is 60 years old this year and looking at pictures over the years greatly unchanged.
